Introduction

On behalf of our development team, we want to thank you for choosing the TX-500 Discovery.
The TX-500 is an ultra compact all-mode transceiver ideal for travelling. Its compact size and weight mean that you can take the instrument to remarkable places, where radio work will give you an unforgettable experience.
The strong casing, protection against splashes and dust ensure the use of TX-500 in extreme conditions and guarantee its reliability. A sharp monochrome display will allow you to clearly see the information in either bright sunshine or low light, thanks to a multi-mode backlight.
The transceiver parameters and functions will also make it possible to successfully use the unit at a home station or as a mobile version. Record-low current consumption in reception mode (up to 110 mA) will extend the battery life, providing for longer stay on the air without recharging.
Because the TX-500 is a software-defined radio (SDR), you can expand its capabilities using computer applications and adding new features with free firmware updates. The TX-500 Discovery has an integrated high-performance spectrum analyzer, allowing you to see signals before you hear them.
It’s high time to go off into the deep blue yonder, taking the TX-500 with you.

Protections

OVERVOLTAGE PROTECTION
When exceeding 15.0 volts, the transceiver won’t allow switching to TX mode, (the voltage indicator on the display will become inverse) a significant excess (more than 16 volts) it can cause the protective fuse to burn out, as well as the failure of the transceiver! Use a power source or battery with a voltage of 9 to 15 volts and a current of at least 3 Amps.
ATTENTION! Exceeding the supply voltage above 15 volts can damage the transceiver!

REVERSE POLARITY PROTECTION
If you connected a minus voltage source or battery instead of a plus, the transceiver will not turn on. You must connect the external power supply correctly, please, see the pinout of the power connector in the section “Controls end user interface”.

OVERHEAT PROTECTION
The transceiver has an internal protection against the overheating of the output stage of the transmitter. If the TX continuous mode is too long, the output stage as well as the transceiver body can be heated up. If the limit value is exceeded (about 60 degrees Celsius), the transceiver won’t allow switching to TX mode.
After the temperature drops, the TX prohibition mode will turn off automatically.

ATTENTION! During long-term TX mode (digital modes) do not block the air access to the rear cover of the transceiver, or reduce the power.
TIP: Unfold both rear legs to increase the air flow convection.

HIGH SWR PROTECTION
If the impedance of the antenna is different than 50 ohms and there is no antenna tuner connected, the SWR indicator on the display will show a value greater than 1.0. If the SWR value is 3.0 or more (the SWR indicator on the display will be inverse), the transceiver will automatically reduce the power output. If the value of SWR is greater than 3.0, then the output power will decrease more.
ATTENTION! Use a tuned antenna with a wave impedance of 50 ohms, this is ideal (max output power), or use a matching device (automatic or manual tuner).

Basic Operations

GETTING STARTED
Before using the TX-500, you’ll need to connect a power supply, speaker- microphone and an antenna, at minimum.

AF GAIN — Controls receiver AF gain (volume).

USING THE MENU
The menu is used to tailor the transceiver to your operating preferences.
To access the menu, push until the any menu entry appears in the pan-adapter area. To change the value of a menu parameter, rotate TUNE/MULTI (large knob).To exit the menu, push again.

BAND SELECTION
The TX-500 covers the 160-6 m amateur bands. Characteristics of each band are summarized below.

MODE SELECTION
Each mode is described briefly below. Later sections cover each mode in detail. Tap MODE one or more times to select USB (LSB), CW (CWR), DIG, AM or FM mode. Long push selects alternate modes, such as CW reverse (CWR). Also, long push returns normal mode.

• SSB: Single-Sideband modes are narrow-banded voice modes that conserves space in crowded band segments. They’re the most popular modes overall, they are: LSB (lower-sideband) usually used in 160, 80 and 40 meters, while other bands use USB (upper-sideband).

• CW: Continuous Wave mode requires narrow bandwidth, providing a high signal-to-noise ratio which is ideal for low-power (QRP) use. It’s also a popular mode for Ding and contests. CWR Continuous Wave Reverse is the alternate mode, and may reduce
  the level of interference (QRM).

• AM: Amplitude Modulation mode is characterized by good fidelity. It’s much less power efficient than SSB modes. You can easily find AM amateur stations in 160, 80, 40 and 10 meters.

• FM: Frequency Modulation mode is most often used for local communications, and can be found on 10 m and up.

• DIG: Digital Mode is usually used with a computer connected to the transceiver to send/ receive data. Although SSB modes can also be used for this purpose, the TX-500’s audio based data modes DIG optimize settings for data rather that voice.

VFOS A AND B
The TX-500 provides two VFOs. Use of VFO B is optional. Each VFO has independent frequency, mode, and filter settings:

• VFO A normally controls both the receive and transmit frequency. Most contacts occur between stations tuned to about the same frequency.
• VFO B can serve as a holding register for a second frequency of interest, then swapped with VFO A as needed (see A<>B).
•  + – Tuning rates: Tapping selects VFO tuning rate LSB, USB, DIG (10Hz, 100Hz, 1kHz, 2.5kHz, 5kHz), CW, CWR (1Hz, 10Hz, 100Hz, 1kHz, 2.5kHz), AM, FM (100Hz, 500Hz, 1kHz, 2.5kHz, 5kHz). SSB stations often align on 0.5 or 1.0kHz boundaries.
• A->B To copy VFO A’s frequency to VFO B: Tap  . Tapping also copies VFO A’s mode and filter settings to VFO B as well.
• B->A To copy VFO B’s frequency to VFO A: Tap . Tapping also copies VFO B’s mode and filter settings to VFO A as well.
• A<>B VFO A and B swap: Tap to exchange VFO frequencies, modes, and all other settings.

Due to the special feature of the internal signal conversion, there may be a certain number of frequencies that can be heard in the headphones as clicks. This is not a hardware problem, it is the features of the device architecture. In this case, we recommend using the DIF function.
RIT
Incremental Tuning, or receive incremental tuning, provides a means of adjusting the receive frequency without affecting your transmit frequency. This control is sometimes called a clarifier since it can be used to tune in SSB voice signals. But RIT can also be  used in all modes, in the event that a station calls you slightly off-frequency. RIT and XIT use the tuning rate (1/10/100/200/300 Hz), taping .
XIT
XIT or transmit incremental tuning, adjusts the transmit frequency without affecting the receive frequency. RIT and XIT use the tuning rate (1/10/100/200/300 Hz), taping .

• To use RIT or XIT: First, tap RIT (RX mode) or tap XIT (TX mode).
  This turns on the “+0” on the display. Then adjust the offset using RIT/XIT knob.

• To zero the RIT/XIT offset tap .

VFO LOCK/UNLOCK
When the mode is activated, the inscription appears in the upper line of the display J (lock), frequency tuning is not possible. To deactivate the mode, press the button **again.
TRANSMIT SETTINGS**

• Voice Modes (SSB, AM, FM): Choose a mode: Tap MODE to select mode.
• MON, Monitor: Push in the bottom line for MON on. Hold PTT to set the voice monitor level, rotate AF GAIN knob. High MON settings may result in audio clipping or distortion. Start with 3 to 5.

Do not use the hand speaker-mic at the same time as monitor MON function in voice modes — this creates the risk of audio coupling with high noise levels, distorting the real sound.

• Adjust mic gain level: Push and select MIC, rotating TUNE/MULTI.
  While speaking into the mic, adjust  >09 > Gain > MIC (mic gain).While speaking, adjust mic gain for maximum 5-7 bars on a scale. Mic gain for the TX-500 mic is typically 3-7.

• CMR Speech compression: To use speech compression, tap in the top line.
  Adjust the level using the >16 > CMR Level or long push . High CMR settings may result in distortion. Start with 1 to 3.

• POWER: Set the power level (10-100%): tap in the top line and rotate the knob
  TUNE/MULTI. Do not use MIC gain to set power level. Set mic gain to a fixed level as described above.

• VOX: Selects push-to-talk (PTT) or voice-operated (VOX) transmit (G icon on). VOX hold time is set with >14 VOX > MIC (time, ms). >13 VOX L (VOX level) should be set to trigger at normal speech level, but not in response to incidental noise. Start with low settings (80-90).

• VOX Transmitter keying method: The VOX switch selects either VOX or PTT keying for CW mode. Most operators use VOX, allowing the transmitter to be keyed immediately whenever a hand key or keyer paddle is used. Tap in top line and  rotate TUNE/MULTI or tap >14 > VOX > CW (time ms).

• METR: You can switch the transmit bar graph from MIC, ALC, PWR, SWR, PWR Num, SWR Num, by tapping N>METR in the top line. Rotate MTUNE/MULTI knob.

• CW modes (CW, CWR): To swath modes tap D to select C (CW normal). In some cases an interfering received signal can be eliminated by switching to D (CW reverse) using long push D.

• CWPITH: Set sidetone pitch using CWPITCH. The ideal pitch for most operators falls in the range of 600-700 Hz. The receiver’s passband will be centered at the pitch you select. Tap and rotate TUNE/MULTI or  >02 > CW Pitch (Hz). Set sidetone volume using AF GAIN in TX mode, MON.

RECEIVE SETTINGS

• RF gain is normally left at (-0). Reducing RF gain may be useful in some strong-signal conditions.

• SQL: Squelch is used to mute the receiver until a signal appears. The control adjusts the signal threshold required for squelch to “open,” unmuting the receiver.

• IF DSP: Virtual Intermediate Frequency: Specifies the Mode of the Receiver.
  ENABLE: This is the operating mode, utilizing all DSP features of the radio. This mode uses a virtual Intermediate Frequency, which is offset from the operating frequency by a few kHz. This is similar to ‘homodyne’ technology.
  DISABLE: When IF is disabled, the radio operates in simple Direct Digital Conversion mode, and has soft reduced performances.

• FILTER: DSP filter tuning functions (LF/HF) The (LF/HF) control is used to shape the TX-500’s receive filter passband. In general, a narrow passband reduces interference (QRM) and noise (QRN), while a wider passband improves fidelity. In voice modes, CW and DIG modes long push selects low-cut (LF) and high-cut (HF) frequency. Pushing select number of filter (1-4)RX, (1-2)TX. These functions remove low- or high-pitched interfering signals.
  Reducing the width or shifting the passband may attenuate an interfering signal above or below the desired one.

• PRE/ATT: Preamp PRE and Attenuator ATT turns on the RF preamp. It should be used only when signals are very weak. Preamp gain can be set on a per-band basis. ATT turns on the 20-dB RF attenuator, which can protect the receiver from strong interfering signals.

• NR: Noise reduction removes random background noise (hiss or static). It has a characteristic “hollow” sound. Higher settings may attenuate weak signals. Tap turns on noise reduction, holding and displays its setting, which can be adjusted using the knob MTUNE/MULTI.
  Tap return to exit the setting display. Tap again to turn noise reduction off.

• NB: Noise blanking NB can eliminate repetitive noise such as that from power lines, appliances, and vehicle ignitions systems. The NB setting is adjusted in the same way as NR (see above).

• NF in SSB and AM modes, NF turns on auto-notch, which locates and suppresses one or more carriers automatically, Push NF to enable or disable the Notch Filter.

• TONE (Transmission tone): The transceiver will transmit a single tone. Pressing “Tone” again puts the transceiver in RX mode. A long press of TONE displays the selection mode NORMAL (1000 Hz) or DUAL (two tones of 1000 Hz and 2000  hz). The transmission power is approximately 50%.

EXAMPLE (RX) SSB FILTER ADJUSTMENT: (CHANGE FIL-3)
Set FIL-3: Bandwidth: 2.4 kHz; Passband: 600Hz to 3kHz

1. Long-Push FILTER to enter filter adjustment menu. The parameter to be adjusted is shown in the bottom line of the display.
2. Push Fil until FIL-3 is selected (in the bottom line).3. Push once to select “HF”. The display might now look like this: “ RX SSB FIL-3, HF2700”. (‘2700’ might be any other value).
3.  Rotate MTUNE/MULTI to change 2700 to 3000 (notice the frequencies are in Hz, not in kHz).
4. Push   to save changes and exit the filter adjustment menu.
5. CHECK YOUR WORK: Push a few times until FIL-3 is selected. It should now display 2.40 k.

Advanced Operating

FREQUENCY MEMORIES
V/M (VFO/Memories) — The TX-500 has 100 general-purpose frequency memories (00-99), Each memory stores VFO frequency, modes, and other settings.
To store a general-purpose memory (00-99): Push V/M , then locate the desired memory by  rotating the MTUNE/MULTI knob. The VFO frequencies presently stored in each memory will be shown as you scroll through them. When you reach the desired memory number, push >Mem to finish, or tap V/M to cancel.
To recall a general-purpose memory: Push V/M , then select memory 00-99 using V/M MTUNE/ MULTI. Tap V/M to exit.
To erase a general-purpose memory: While scrolling through memories to save or recall, push CLR.
DIG MODES (AUDIO DATA MODES)
Many audio-generated data transmissions can be heard on the bands, using PSK31, RTTY, JT65 and other modes. A computer, sound card, and appropriate software are normally used.
DIG mode is provided for this purpose.
Unlike SSB modes, DIG disables MIC and enables use AUDIO cable (connector REM/DATA).

Also DIG mode has individual audio level settings. Upper sideband is the default.

RX / TX switching can be via CAT cable (see Remote Control). You can also use the VOX function (see Basic Operations).
DIG mode settings:

SPLIT AND XIT
Sometimes you’ll hear a DX station being called by many other stations. To ensure that he has a clear transmit channel, the DX station may say “UP” or “DOWN” to indicate that he’s listening above or below his transmit frequency.

To use split, first tap to set VFO B to the same mode, frequency, and filter settings as VFO A. Then tune VFO B  up about 2 kHz. Finally, tap (the  icon will turn on). VFO B is now controlling your transmit frequency.

This is where the switch comes in: it reverses the A and B VFOs so that you’re temporarily receiving on your transmit frequency. During this time, tune VFO A around a bit to see if you can identify who is presently working the DX station, then position yourself just above this frequency. With any luck your next transmission will occur right where he’s listening.
XIT as an alternative to split: If you’re trying to preserve VFO B as a holding register tuned someplace else in the band, you may want to use XIT rather than split in the above situation. In this example, you’d turn on XIT and rotate the offset control to about +2.00 kHz. You’ll then be transmitting 2 kHz above VFO A. To do the equivalent of A<>B, you can briefly turn RIT on as well. Turn off RIT to listen to the DX station.

RECEIVE AUDIO EQUALIZATION (RX EQ)
The TX-500 provides 3 bands of receive audio equalization via the 18 EQL > RX menu entry. EQ RX can compensate for physical acoustics (of the room, headphones, internal speaker, external speaker), tailoring the audio to your personal preference.

TRANSMIT AUDIO EQUALIZATION (TX EQ)
If required, transmit audio equalization can compensate for microphone and voice variations.
18 EQL > TX works exactly the same as EQ RX, and can be used during transmit. EQ TX is not applicable to CW. While adjusting EQ TX, monitor your voice using headphones (use N>MON to set the level), or listen to your transmitted signal on another receiver. If you hear distortion, reduce all EQ TX bands. You may also have excessive mic gain or compression.

 Most microphones, including the TX-500, will provide good audio quality with little or no EQ TX. High settings can cause distortion.
Do not use the hand speaker-mic at the same time as monitor function in voice modes ( ). This creates the risk of audio coupling with high noise levels, distorting the real sound.

CROSS-MODE OPERATION
(CW-in-SSB) Cross-mode operation is possible in some cases. For example, you could set up VFO A for SSB receive, and VFO B for CW transmit, then enter N>SPL.

EXTERNAL POWER AMPLIFIER CONTROL
To control the PTT function of the power amplifier, you must connect pin 2 (PTT OUT), open collector, of the REM / DATA connector to the PTT control relay of the external power amplifier (usually this is the “PTT” connector). Also, pin 7 (GND) of the REM / DATA connector must be connected to the GND of the external power amplifier.
It is also necessary to connect the BNC type “ANT” connector of the transceiver to the amplifier input (usually named as the “TRX” connector) with a 50 Ohm coaxial cable.

If the amplifier does not have an automatic band detection function, then it must be selected manually.
Note: Connecting cables are not supplied.

ATTENTION! The maximum switching voltage must not exceed 25 V and the maximum switched current must not exceed 0.5 A

CW KEYER MEMORY
For recording and later playback of the short CW messages, the TX-500 provides 4 memory slots with a duration of 25 seconds.
To record, you need to press and hold one of the “CWM” keys 1, 2, 3, 4 for more than 1 one second. The icon appears on the screen. Then, you can perform your own CW manipulations, and at the end, press shortly the same “CWM” 1, 2, 3, 4 key.

To play a recorded message, press shortly one of the “CWM” 1, 2, 3, 4 keys. The icon will appear on the screen. Pressing shortly will stop playback.

VOICE MESSAGE MEMORY
For recording and later playback of the short voice messages, the TX-500 provides 2 memory slots with a duration of 20 seconds each.
To record, you need to press and hold one of the “VXM” keys 1, 2 for more than 1 one second. After one second the   icon appears on the screen. Then you can dictate your  own message, and at the end, press shortly the same “VXM” 1, 2 key.

To play a recorded message, press shortly one of the “VXM” 1, 2 keys. The icon will appear on the screen. Pressing shortly will stop playback.

Do not use the hand speaker-mic at the same time as monitor function. This creates the risk of audio coupling with high noise levels, distorting the real sound.

Menu Functions

00. Valcoder VFO Encoder Mode Selector
The valcoder specifies the mode of the VFO encoder. Select with TUNE/MULTI.

• Plain: The speed of change in frequency when turning the TUNE/MULTI knob is linear.
  The step is determined by the setting of on the front panel, and is also mode- dependant.

• Intel: (Intelligent) The speed of change in frequency varies with the speed at which you rotate the TUNE/MULTI knob.

Default: Intel
01. IF DSP (Specifies the Mode of the Receiver) Select with TUNE/MULTI

• ENABLE: This is the operating mode, utilizing all DSP features of the radio. This mode uses a virtual Intermediate Frequency, which is offset from the operating frequency by a few kHz. This is similar to ‘homodyne’ technology.
• DISABLE: When IF is disabled, the radio operates in simple Direct Digital Conversion mode, and has reduced performance.

Default: Disable

02. CW Pitch Defines TX “Offset Frequency” for CW Mode

• Adjustable with **** TUNE/MULTI from 400Hz to 1200Hz.
  When working CW, the transmitter’s frequency must be offset from the received frequency such that it is equal to the frequency of the tone at which the operator wishes to copy CW. This automatically zero-beats the TX signal with the QSO partner’s received signal.
  Different operators prefer to listen to different tone frequencies.
  CW Pitch enables the operators to set the offset to their preferred tone.

Default: 700Hz
03. CW Speed Defines the speed of the built-in Auto-Keyer

• Adjust the speed of the Auto-Keyer with **** TUNE/MULTI. The minimum speed is 10cpm (2wpm), maximum speed is 300cpm (60wpm). Default: 100cpm

• Adjustable with MTUNE/MULTI from 2:1 to 4.5:1.

Default: 3:1
05. CW Key Type / Auto / Rev Select sub-menu
The default is mode Iambic A, which is a little more forgiving for first-time operators. Mode B may be preferred by operators who learned to do “squeeze- keying” with another keyer having this or a similar mode. Both modes provide dot- and dash-memories enabling fast code speeds, but with slightly different timing. Change values with **** TUNE/MULTI.

• Type: Single (Straight Key) or Paddle.
• Mode: Iambic A or Iambic B.
• Rev: Disable or Enable.
  When Enabled, the dit and dah side of the paddle are reserved. Side of the paddle are reversed. Preferred by left-handed Ops.

  Default: MIC = 5; DIG = 20.

10. NR Level Noise Reduction Level.

• Select adjust with TUNE/MULTI .
  Digital Signal Processing (DSP) feature for reducing noise on a noisy band. NR is most effective on CW. It is also effective on SSB, but degrades the fidelity of the received signal somewhat.
  Default: 50
  Adjust for most effective noise reduction.

11. NB Level Noise Blanker

• Adjustable from 40 to 100 with TUNE/MULTI.
  The Noise Blanker is a DSP feature used for reducing certain types of pulsed noise (i.e., lightning or automotive ignition noise).
  Default: 50
  Adjust for best noise reduction.

12. SQL Two types of Squelch: SSB/AM/FM

• SSB/AM
• FM
  These are independently adjustable. Select adjust with TUNE/MULTI.
  SSB/AM also works DIG mode.
  Adjust threshold from 0 to 100 with MTUNE/MULTI. On a clear (unoccupied) frequency, adjust threshold level until the audio just barely shuts off and on the right of the screen lights up.
  Defaults: SSB/AM = 0; FM = 0.

13. VOX L VOX Sensitivity Adjustment
