Dan -
Several possibilities.
First try exercising the BAND and FUNCTION switches. A little DeoxIT would be a big help. Next,
unplug and replug the crystals, again with a little DeoxIT.
You say it makes RF on 160 / 80 / 40. I assume you have the optional 160M crystal (12.6 MHz) in one
of the extra sockets? First question is, is the RF _in the right place_ .??
A failure of anything in the PreMixer signal (PTO or BAND oscillators) will allow the transmitter to
tune up on 5.645 MHz (Carrier Oscillator frequency) around 3 or 7 on the RF TUNE linear scale.
If you connect it in TRANSCEIVE under RCVR control does it work??

Howdee Fellow Drakeheads!
I have a B-line that I am trying to put back in service. It worked FB a couple of years ago and
then I didn't use it much for about a year and then moved and it spent another year on the shelf.
The R4B works great, but the T4XB has a prollem. I wonder if any of you gurus can help. It will
tune up and make RF on 160/80/40, but the peak of the RF tune control on 40 occurs in the 160/80
area of the control, not in the 40 meter area. The other thing is that there is no RF at all above
40 meters on any of the bands. Is this something that is common...er whut?
I will be looking at stuff but I thought I would ask and see if there is knowledge here on where
to start?
Thanks a bunch es
