Did you receive my email to your email address
regarding possible future copy for the RadCom Column
So. you're saying, for the olde-mann ident stage, it
would be preferable to introduce a carefully designed, non-linear chirp along
with a bit of PR noise. That can be done with a PIC / DDS
combination, so a direct upconversion based beacon should be able to
manage it. But a PLL or RDDS based one can't hack it
For all the use the CW ident is, might as well
do something special and use some artistry for its sound.
Now there's a thought for any GB3SC# update - a custom CW

It is a
GLORIOUS sound Adrian,
expecially after it has travelled 342km to reach here, which, as you know, it
does quite often. I like PI7RTD as well, and all of the others the whoop and
slide and chirp. Perfection is boring, at least for the CWID.

Whilst the idea of keying the 5Mhz sounds interesting ..I fear that the
df/dt of the keying by the time it had gone through the PLL would be
pretty poor..as you can hear the exisiting keying is no wonderful! https://www.beaconspot.uk/beaconsnd.php?beaconcall=GB3KBQ
