Hi Noel,
Thanks for the post.

a regular signal (or maybe two as there was some bursts of a noticably
different length) that I could not decode nor identify. I played around
and decided the signal was about 510 Hz above where I was tuned, which is
for tone frequencies of 10.149.200 and 10.149.400 - ie I am set at
10.147.600 USB and using a 1600/1800 tone TNC.

10.151.500) but actually using a 1600/1800 TNC - or a TinyTrak 3, or (2)
using USB with the dial set for a 1600/1800 TNC (10.147.600) but actually
using a PK232 or AGW.

rig (set for USB and to 10.147.600, the standard frequency for a 1600/1800
tone TNC, and unchanged from successfully decoding other beacons) into my
TNC, but at the same time feeding some audio to the sound card, and using
AGW to decode.

I think it was decided that we all tune to VK3MY-3.
Regarding off frequency, this maybe true, as I only tune to resolve
VK3MY-3.I think it was decided that we all tune to VK3MY-3. This I hoped
would put me on frequency. Perhaps the radio IC-735 needs RX and TX to
be recalibrated(?). I'll look into this.
Is there anyone that can check VK3MY-3 please?
I'm using a Kam+.with UI-View and running compressed beacons.
The antenna is a 1/4wave vertical, using the roof of the house as a
ground plane.

see my prevoius two postings) and has plotted via UI-View as being (on a
small scale map of Oz) in the Adelaide region. His pos is 34.10.81S and
142.09.21E, and a comment of "HF and VHF Igate".

Cool. I heard VK3MY-3 (it probably is the station that has the longer
beacon) almost all weekend, often 15 times an hours. It seems shorter
skip is getting better too.
