Most of us in the forum have the rigs from hfsignals.com
Do you have one of these from Sunil?
? ??
Most of us have no idea what transmit current into the exciter should be on Sunil's board set.
I suspect Ashhar does not either.
Anyway, my guess would be that current increase when going to transmit on that exciter would mostly be around Q14.
I suggest you measure DC voltages at Q14's emitter, base and collector for transmit and receive.
Should be around zero for receive, well above ground for transmit.
Also, if you want to keep an intelligent conversation going on this, don't change the subject heading.
Took me a few minutes to find your old thread where the problem was described.

In order to provide help we would need to know a bit more about your problem.
- Which model BITX do you have?
- What test equipment do you have available?
- What are the symptoms of the problem?
- How far have you already gone with testing?
The group is usually quite helpful but "something is broken" is just too little?
information to work with.

I have a BITX20 with some problems with the current measurements and cant seem to get any help with this group. I would have to say i am very discouraged. Ill just contact Ashar.
