Hi Folks,
Been kicking around putting the 0.5PPM TCXO in my K3. After doing some reading
a question or two arises. The instructions sheet(s) for the TCXO mentions
using method 1,2 or 3 in the K3 manual to set frequency. The K3 manual does
not have a method 3 as I can find. I've checked the reflector archive and
found there is a data input feature in the K3 utility for inputting data
received with the TCXO. I think this equals method 3. Someone make a note to
change instructions/manuals if needed.
My question is do I need to do a method 1 or 2 before doing the data input?
Method 1 is to use a freq counter. My freq counter is only about +/- 10 Htz
depending on variables. Method 2 is zero beat. By ear the best I can get is
about +/- 25 Htz. How close do I need to get with method 1 or 2 (if needed)
before inputting the data?
Second question, will the 0.5PPM TCXO eliminate the hysteresis I see during
RTTY? Depending on whether I tune to a signal from low to high or high to low
I can see 10+ Htz difference in the signals frequency. Or, are other factors
at work?
Constructive thoughts appreciated.
Happy New Year. 73
Jim, W0EM
