Dear Drakies,
1) I had the bright idea to replace the tubes in my R4B.
Now I can not zero or calibrate the S-meter. I was unable to find two 6HS6
tubes. I suspect this has thrown the S-meter bridge out of balance. It worked
fine with the weak tubes. Where can I buy a set of 6HS6 tubes?
2) I have a TR4CW. I was tricked into buying it, when I thought the CW stood
for morse code. I do not operate SSB. Has someone already figured out how to
change the IF crystal filter for a narrow bandwidth for CW?
What center frequency do I need to use? I can always restore the TR4CW to
original, should the need arise. In the mean time I will be using an external
receiver with selectable bandwidths.
3) I see there is a RIT modification for the TR4CW. Does someone have a reprint
of that article?
