Can someone in HS repair my 30 meter band QRP rig?
« on: July 11, 2015, 08:58:46 AM »
I have just bought a QRP, PSK rig from an overseas company.  It operates on a fixed frequency in the 30mb.


Although the rig is brand new, there seems to be a problem with the audio out circuit.  A strong test signal from my HF rig is passed through, but weak.  If I connect my QRP rig to antenna and my sound card, the waterfall background audio level is -20, with nothing present.


I use PSK rigs everyday with the same audio cable, sound-card, sound card settings etc.  Therefore, after testing/swapping cables, sound cards etc, I am sure there is a problem with my new QRP rig.


I have the circuit diagram of this simple rig.


I do not want to post the rig overseas for repair, (because I have lost rigs in the post on previous occasions).


I do not have the necessary test equipment to fault-find this rig.  I need a scope, maybe RF probe etc.


Is there someone in Thailand who can repair this little rig, trace the RF input signal through?


I think the RF transmit side works fine.


The fault is probably something simple, a dry joint or whatever.


Of course, I am happy to pay a repair price
