I have a Radio Shack HTX-10 10 meter xcvr that does not transmit on
USB or LSB but works fine (at least into a dummy load) on AM and FM
and its receiver also work fine.. Any ideas what I may be doing wrong?
I would assume (possibly a fatal error on my part) that the transistor
finals are not blown, otherwise I would not have power on AM - FM.
Right? Any suggestion would be appreciated.
