Hi all,

I have the above set-up. When set up for transceive operation using 
either the TX or RX VFO (i.e. anything but "separate" mode) I find 
that the position of the Preselect/RF Tune control on the "master" rig 
(be it R4C or T4XC) has to be set differently for either max power out 
or best receive "peaking". It seems particularly poor on 21MHz and 
28MHz band i.e. when set for best RX performance it is way off peak 
for TX with hardly any power out at all. When set for max power, the 
RX is way off peak and "deaf". Ideally obviously the preselector/RF 
Tune control should require no or very little adjustment for peak 
performance on both TX and RX. Is it just a case of going thru an 
alignment procedure on both the TX and RX or is there more to it than 
that? Operation in split (separate) mode is just fine, as you would 
expect from the above description.

Any ideas?

Thanks,

David G4GTP

P.S. Slightly off topic.....Worked quite a few stateside this morning 
at about 0900 UTC on our (UK) newly available extended 7MHz band, just 
available today (extra 100KHz to take us to 7.200). Would not normally 
expect to hear USA at all on 7MHz at this time of day. Is it 
exceptional condx or is it just that USA is usually masked under all 
the Euro QRM in the bottom 100KHz of the band! Do you US guys hear 
Europe/G stations reliably at about the same time normally on 40 
meters? Anyway, quite a treat and all on the Drakes of course!
