Introduction
The staff at FlexRadio often get asked about building out a remote HF Station.
So, I was asked to put some ideas together to get people thinking in the right
direction. This is for today’s ham radio operator to help automate his
station.
Also, by the time you read this, vendors may have changed and the design of
the product may have also changed. You will have to do your own research.
Caveat: FlexRadio, in no way, supports or provides any warranties for any of
the information shared in this document. It is just a collection of possible
ideas and solutions. It is informational only.
Goals
The following items can be used to build a basic, reliable remote HF station
with minimal investment. These are the basics that will be deployed to help
ensure the radio is online and accessible via SmartLink.
Most of the items/ideas listed here are available off the shelf so that you
don’t have to build them or solder them. 🙂
It is assumed that the operator has a 1 or 2-feedline antenna system, an
amplifier is not part of the solution, and there is no rotator.
- AC Power Supply on and off
- Flex 6000 soft power on and off
- Internet modem auto reboot
This guide is to be used as a starting point for building a station that
allows managing some of the basic concerns, the ability to remotely reboot the
radio and to have the internet modem reboot automatically.
Highly recommended is to have a Windows PC also near the radio on the same LAN
network to allow remote diagnosing of problems and also reliable digital
operations by accessing the PC via many of today’s remote connection software
solutions. This becomes much more important should you be away from the
station for an extended period of time.
Requirements
- Internet – 2 Mb/sec upload network throughput via Cable, DSL, or Fiber. The performance characteristics of cellular or satellite networks are not suitable for reliable remote operations.
- WiFi is required to control the Kasa Web Switch.
- Flex 6000 series radios
- All devices on the same LAN Subnet
- Highly recommended – Windows PC on the local LAN network
AC Power Control
TPLink Kasa Smart WiFi Outlet
The AC power will be controlled via a web switch.
Currently, FlexRadio sells the TPLink Kasa Smart WiFi Outlet. You will require
one of these items that will be used to connect to your 12V DC power supply.
FlexRadio Soft Power Control
- TPLink Kasa Smart WiFi Outlet Min
- Digital Logger AC-powered relay
- RCA cable
These items are used to control the soft power up and down of the Flex 6xxx
radio by making use of the Remote RCA connector on the back of the radio. The
Kasa Smart Control is an iOS application that allows you to control multiple
power outlets from your iOS device. (insert Android if appropriate).
This allows the operator to remotely control power to the radio and 12VDC
power supply.

If your internet connection fails, a smart home becomes a
problem. The best solution proved to be the simplest. As the
FBI says, the most effective way of auto-correcting home network issues,
mitigating malicious cyber-attacks and is by routinely cycling power to your
modem and router.
Note: These items have not been tested.

Recommendations
Remote PC (highly recommended):
FRS does recommend that the Operator install a remote PC (desktop or laptop)
at the remote station to allow for remote access maintenance. This can be used
to update the software on the FlexRadio 6xxx. Other options are it allows
remote access to your Router should any changes be required.
At the same time, digital mode operation can be executed on the remote PC and
this provides a much more reliable Digital mode of operation by not sending
SmartSDR DAX data over the internet. Streaming DAX data can consume a
significant amount of upstream bandwidth and impact the user experience.
Remote access to the PC can be achieved by using any of the following software
tools (but not limited to).
- Chrome Remote Desktop
- TeamViewer (risky as TeamViewer may lock you out if they think you are a commercial operator)
- Any desk
Watch: HF Remote – Why a PC at the remote end? – Flex Radio
UPS – Uninterruptible Power Supply
A UPS is highly recommended to be installed for any computer, router, or
modem. A UPS is not required on the Radio power supply but it doesn’t hurt if
you have one that is big enough for 2000-watt power surges from SSB voice
peaks.
Drawing Overview
Other Hardware to Consider
iBoot G2
iBoot-G2+ Expandable Network Power Switch
Model
iBoot-G2+ has the extra features you need to make even fewer site visits.
Control up to three independent outlets to protect even more devices.
iBoot will save you time and money by reducing costly downtime. Just point
your browser to the iBoot, login and you are one click away from bringing that
failed system back to life. iBoot will even detect failed systems and take
immediate action.
It has an auto-ping feature that will verify the modem/router’s accessibility
as required for an outage.
Note: I would like to recommend this, but we need to test it to see if it will
control all 3 devices (12V power supply, Radio software reboot, and the
modem/router).

Accessories
Amplifiers
You will want to invest in an amplifier that a solid-state no tune amplifier,
such as the FlexRadio PGXL.
The PGXL integrates with a FlexRadio 6000 seamlessly and allows legal limit
power. As well, all the health of the amplifier is shown within the SmartSDR
application.
Other amplifiers may also function, however, you will have to discuss that
with your dealer/vendor.
240VAC Power Control
One of our hams recommended this switch.

Antenna Switching
The 403A 2×8 antenna switch works very well with a FlexRadio solution as it is
a LAN based device. When coupled with a Flex 6600 or a 6700 it allows both ANT
1 and 2 access to up to 8 unique antennas.
Other solutions are available (again, ask in the FlexRadio Community) and they
will even integrate well into the CAT/BCD data available directly from the
rear of any Flex 6000 series radio.
Lightning Mitigation
Hardware Solutions
Unfortunately, there really isn’t a very good or comprehensive solution. Like
any ham shack, you do need to do all the standard precautions. What we really
need is an application that will throw the antenna feedlines out the window
when needed. Sadly, that isn’t very practical today.
The Dual Antenna Disconnector by Paradan Radio is a good start but it will not
survive a direct lightning strike.
This device requires a switch 12V DC to turn on and off. If you use a Web
relay to turn on and off your DC power supply then this can be wired directly
to the power supply and ground your antennas when you turn off your station
power supply.

Ward Silver N0AX has a book that every amateur should read and own. You can
find it in the ARRL Book Store. “Grounding and Bonding for the Radio Amateur”
