Hi Graham,
If you can pull the crystal a bit (which should be ok with a
series C, or a combination of L+C), it's ok.
If you can only operate on exactly 472.5 kHz, potential QSO
partners on the continent may have a problem to receive you
because there is a permanent carrier on 472.5 kHz, sometimes quite
strong in this part of DL.
Depending on the other side's filter bandwidth, a few dozen Hz
away from 472.5 kHz to either side will improve things.
If I had to use a fixed xtal frequency, I'd go for 472.3 to 472.4
kHz. Still close enough to be heared by lazy people (like myself)
who 'park' their receiver on 472.5 kHz with 500 Hz IF bandwidth
while doing other things in the shack :o)
Cheers,
Wolf .

472.5 KHz OK for Xtal CW qrg ? GB4FPR
I did ask this a while ago, but to re-confirm
suitable qrg for xtal cw 472.5 KHz ?
Tnx -G..
