[Premium-Rx] Receiver Frequency Display Accuracy & Calibration

[Steve Stutman]

Hi,

Your post will undoubtedly stimulate discussion of passband and its 
relationship to baseband.

Classical seat of the pants method is to zerobeat WWV. I was doing this 
last night with my Frankenstein RX; seems to work as well as ever. 
Assumption of course is that it's 0200 and you know where your BFO is 
(in relation to your IF).

I have used and measured RXs that were cal'ed using the HP catalog; freq 
accuracy not necessarily much better than those set up with zerobeat 
procedures.

It's worth noting that a number of people who do well in ARRL freq 
measuring tests, do so with simple gear. I believe that Frank Carcia's 
cousin generates the test signal.

BR,
Steve
