HF (0-30MHz) Transceivers

Kenwood TS-850 S/AT

The radio I’m now using is a Kenwood TS-850S with the optional automatic antenna tuner (ATU) fitted.
I purchased this radio for a bargain price with a minor, but common, fault; this being very low received audio volume.
Once I had got the radio home and on the workbench I set about the repair and very soon the radio was back in good health once again.

While it was apart I replaced the lithium memory back-up battery as these have a well known problem with leaking causing damage to the PCB, I also noticed it has been fitted with the optional filters, happy days!

The Kenwood is a very capable radio and can transmit from 160m to 10m producing up to 100 watts
of RF power, and has general coverage reception from 30KHz to 30.000MHz.

Yaesu FT-747 GX

Also to be found in the shack is a Yaesu FT-747 GX. These were originally built around 1989/90
the FT-747 is a very basic but capable transceiver. During it’s initial marketing period, it gained the nickname of “plastic fantastic”. The nickname suited it quite well as it was an incredible radio at the time.

It doesn’t have all the bells & whistles with lots of knobs and buttons, it simply has the controls that are needed making this ideal for easy mobile operation. Although this radio is old, it’s still spot on frequency and capable of exceeding the specified 100 watts of RF output. My reason for purchasing this particular radio is primarily to have it available as a back-up radio should the Kenwood fail.
