Bill,
Your dial. There was an article in QST about using a good one to copy the
print to a CD blank (like the ones on top of a CD stack). I know the author
was not Garey Barrell, but he I think he may have had the original idea.
Caveats Garey?
Just and idea. If you're like me sometimes
Dear all,
I am looking for a AM filter for my Drake R4C; I would be happy with
both the 4 kHz or the 6 kHz filter, doesn't matter if original or not.
If someone wants to depart from his/her filter and is willing to ship to
Italy, I will be pleased to get in touch. I can pay via Paypal.

Is it normal for the T-4XC plate current to read 120 mA when:
1. in CW mode
2. Xmitter is keyed using mic line (no mic element connected, just foot
switch).
I have adjusted the bias per the manual at the mark on the meter.
If not normal, any ideas as to what the issue may be?
Thanks
When tuning the T-4XC on 160 meters, into a dummy load, the load control is at
zero or maximum capacitance.
I clearly do not get a peak in output power when changing the load control, the
Pout continue to increase until I hit zero on the dial (max. cap).
The plate control clearly has a peak at
Do you have a key plugged, and 'open'?
Will the current 'dip' with the PLATE control?
Is GAIN control at CCW?

Has anyone on here installed a Harbach SS-400 type Soft Start kit in their
L-7? (This is the kit with the single relay and single dropping resistor
and not the one used in a Heath SB-220). I know the SS-400 was made to
install in a L-4B amp. I have not really studied the room requirements,
