Thanks Chris - that explains it - I've hrd
you wrkg split with Mal & wondered why - all now
clear.

My apologies . .
I have both vfo and xtal control (502.3 and
503.3) and can zero beat with my RIT.
I sometimes forget to switch from XO to
VFO - :-(
In future I shall net on to the station I am calling to avoid
difficulties.

Alan,
Thanks for all info. Ray has
502.6 & 501.6 cc.
Suggest use two xtals if mixing - use
divider with cer-res [to divide drift].
Beacon on 501.5 now - will lsn 502
shortly on off-chance - static low here, at present.
Rog.

Ah, but nobody said it was supposed to be easy :-)
Chris
is always 300Hz HF of me. I think he has a DC transceiver,
possibly
without TX offset.
Dunno whether Ray is rock bound or not. I suspect he
is. I couldn't hear
him this morning at all but Chris/XIZ copied him OK.
I'm hoping moving
the loading coil towards the tower and reducing its size
will reduce
losses, stabilise the resonat frequency, and perhaps improve
receive a
tad.
I'll try to hear you tomorrow at 6am, but if it
keeps raining there is
little chance because my aerial shifts resonance
down to 495KHz in the
rain!
I'm thinking of building a transceiver
for 500K so I can net on other
stations and to free up my FT1000MP Mk5 for
HF again. Rapid has xtals
and ceramic resonators that appear suitable. For
example, xtals on 4.194
MHz and resonators on 3.69 (504KHz nominal
difference). Another possible
pairing is 4.096 and 3.58 (516 difference).
Both will need the ceramic
resonator pushed up a few KHz with a variable
cap in series with the
nominal 20pF load, but I'm assuming that is not a
big deal. The crystals
are only 20p each so filters should be inexpensive
even if I need a
bucket load to get a set within 10% of the target IF
bandwidth.
CUL,
Alan
