Hi,

Apologies for writing this in English, but my Swedish language is still under construction:)

I have a Yaesu FT-7B. (which is one of my most favourite rigs). I believe that it has received RF up the power supply cable and now has a "sick" front end on the receiver.

I am looking for someone to find and fix the problem.

Is there a dealer or service somewhere (prefereably near Östervåla 740 46) that maybe able to help me?

I appreciate any advise or help that you may have. It is old, but itäs like an good friend!

yaesu service

Have you tried Svebry in Skövde, Svebry Electronics AB ?
They do repair Yaesus, and other. Even older models, like yours, I think. I had my 1983 modell Icom there a copule of years ago. They did a good job on it.
Good luck.

This radio is a huge improvement on the straight FT-7. The filtering on CW is sharper, the SSB tonal quality is clearer and having worked many obscure stations with this radio, 50W does make a difference. I have used the FT-7 without much success. The lack of the majority of 10M was a let-down, and the PA is puny. The FT-7B addresses these issues and refines an already good proven radio into an excellent proposition for mobile/portable and yes, even as the main shack radio. Mine has the YC-7B outboard digital display, which drifts and lies for about 30 minutes. A crystal oven or some form of temperature compensation on the reference oscillator would help here. On the whole, the FT-7B is a fine piece of kit, and you won't find a better 50W radio in amongst the modern stuff on offer. More to the point, being modular and simple, it's very easy to fix.
Beware, though. these rigs are 20 years old and are starting to show their age. When I got mine, two of the five (yes, five) relays had dirty contacts and one of them was beyond repair. Also the microphone cable picks up RF and the audio in should be decoupled at the socket. The power cable is far too long, and should be kept within 1M if possible. Any longer and the voltage drop starts to affect stability of the VFO on TX.

Hi Bernt,

Many thanks for the response.

I have sent Svebrys an email and will send the Yaesu to them as soon as possible.

It will be great to get the rig back and working again.

Best Regards / Phil

Hi,

Thanks for the information. I hadnt seen that before.

I think its a fun little radio and although the neighbours here are not too close to my antennas I still prefer to use low power as much as possible and avoid anything more than 10W.

I appreciate you replying to my cry for help!

Many thanks again.

Best Regards // Phil
