[ARC5] 60 meter operation with the "ARC-5"

[Bill Cromwell]

Hi Ken,

I am sure some people have used those transmitters with xtal control (or 
DDS) and with minimal, reversible modifications. Bobby's has already 
been modified. That's what I would do. I have little personal interest 
in the transmitters - I do have and use some of the receivers (so don't 
kick me out yet).

Frequency stability (long and short term) is probably a matter of 
individual radios and the stability of applied voltages. The receivers I 
use will stay on a received signal (can you spell WWV) all night after a 
few minutes of warmup. I have heard the transmitters are even better! 
Just a rumor, mind you.

If Bobby uses the VFO in that transmitter and it drifts "off" 40 or 40 
hurts I doubt anybody will notice or care. If the right people do care 
he will get a note asking him to fix it. Nobody will be at Bobby's house 
kicking down the door and there will be no decades in a federal 
penitentiary. When he is asked to fix it he can then plug in the 
appropriate xtal.

73,
