And if you radio don't read out the correct frequncy?..it don't matter
what pair of tones you use. :-)


I have never disputed that we are on the wrong frequency.  Having used
my radio on HF USB voice with xtal locked radios, being told to "come up
a bit", I found I was reading 200Hz above the nominated frequency.
Considering this, my readout would be 10.147.8 for HF packet with the
KAM+..or thereabouts.

My readout just "ticks" over to 10.147.9. This is what I was using to
resolve VK3MY-3.  I had 2 KAMplus' one on UI-View and one on a Terminal,
both were decoding ok. with the pair 1600/1800.

Ok so far..?

Now if I don't have a problem, then I'm 300Hz too high. If I do have a
problem maybe about 100Hz high, but nothing like the 500Hz that is being
suggested by Noel.  ?? 

Question to Noel.  You previously stated that your have a MFJ TNC, which
model?  And what radio too please?


If I new for sure that there was nothing wrong with my radio, then I'd
be happy to move down 300Hz. But unless I can prove that my radio is on
frequency, I'll just have to play follow the leader.:-)  And the leader
at the moment is VK3MY-3.  Lets hope to hear from Ross soon.

Alex, I've not heard you on 30m APRS.  In your opinion, what frequency
are my transmissions on 10MHz?

Regards,
Ron
