All ham radio ALE channels are specified by dial (VFO) frequency in
USB (Upper Sideband). The standard ALE 8FSK signal always transmits
FIXED audio tones. The common ham practice of saying the "offset" is
not needed with ALE. The lowest of the ALE 8 tones is 750Hz and the
highest tone is 2500Hz. Th

Hi Andy,
It is still a viable mode often used. Some other modes have other
upsides...mfsk is robust yet fast and narrow and also has pic xfer
capabilities. DominoEx does very well with or without FEC on
160/80/40 and is also a narrow bandwidth mode at that speed.

Leight,
Technically, you are right. All reliable modes (Olivia and DominoEX mainly)
could support SSTV images as in MFSK16. It is just work...

Is there any reason we couldn't have images with Olivia? As far as I
can tell, MFSK images are just plain old SSTV images with a header
specifying size sent in MFSK data. The offset needs to be set for the
different Olivia widths, but that is about it. Am I confused?

After several years, the main digital mode still appears to be PSK31,
especially on the higher bands. When a new mode comes out, some of us
will test it and if it doesn't have some superior feature, may not use

I would argue that following the IARU band plan is following "good

Hi Guys,
For optimal ALE reception you want your RX passband set to 1625hz
when using less than 2.8 or 3.0Khz IF filtering, anyone running a ham
rig with the typical 2.1 to 2.7 filtering will need to enable IF

The ICOM 756 Pro 2 centers on 1500 Hz. If anyone knows if you can change
the center, I would like to know how to do it. My preference would be
1000 Hz since it makes it easier to increment one kHz from the dial
frequency.
As mentioned to Jose, the correct frequency you were operating on was
14
You are of course right, Jose. That was a typo and should have read 14.111.
Thanks for the correction.
