Sommerkamp Yaesu Trio

YAESU TRIO TEMPO-ONE

Similar with a FT200.
I have this unit since 1980… Sleeping in a corner of my shack.
Lot of work to restore it… Bad caps, bad tuning,…
Now it is alive and nice to use.

 


Sommerkamp FRDX500

Our receiver when we were young… Still at home.


Sommerkamp FTDX505

I buy it in a Hamfest in November ‘s 2018 for just 50 euros. This poor transceiver was in very bad conditions. He was sleeping in a wet place during several years and inside is lot of dusty part…

I first clean it, change lot of resistors and caps. Realign it. Now the receiver part is OK. For the transmit part i get around 110w with new 6KD6. But i have a large problem in the mode switch because lot of bad contacts. I have now to undolder all the wires on this switch and to change it with a new one….

Some easy tools to restore it: (thanks Alain F1LAG, my brother)
