All: I have been through the T-4X / R-4B alignment procedure per the Drake
manuals a couple of times with my 4-line. Regardless, they aren't "quite
right". I get a significant amount of TX drive difference with the RX VFO
vs. the TX VFO, and the opposite for RX sensitivity. Best results are when
the VFOs are set to SEPARATE.
I'm using 93-ohm coax between the two injection ports.
Somewhere I read that the load resistor approach to tuneup was really a
mistake, but I'm very interested in how else I should approach this. Leave
the two units connected together during alignment??? Some other approach?
Thanks--this is always a great source for help on the Drakes...
