Re: New Icom M803 SSB

I can confirm I have made contacts with the M803 on 10 meter, 20 meter, 40 meter, and 80 meter bands as a licensed HAM. Note that none of those bands are listed in the TX specifications and the radio has not been modified from factory config.

HAM bands:
80meter = 3.5-4 Mhz
40meter = 7-7.3 Mhz
20meter = 14-14.35 Mhz
10meter = 28-29.7 Mhz

Radio Spec list for TX:
1.6–2.9999, 4.0–4.9999, 6.0–6.9999,
8.0–8.9999, 12.0–13.9999, 16.0–17.9999,
18.0–19.9999, 22.0–22.9999, 25.0–27.5000 MHz

Re: New Icom M803 SSB

For ham radio use, it seems to me that the 803 is decidedly unfriendly even compared to the M-802. I don't have the M-803, but I have the M-802 and have read the M-803 manual.

For stepping frequencies, with the M-802 you can use both hands to make frequency selection and manual scanning quick. Operate the digit selection with the left knob and the stepping with the right hand knob, so you can use both hands. The M-803 requires pushing the quite small left or right keys to select digits. This is clumsy compared to turning a knob, and means you either use your right hand for both digit selection and stepping, or use your left hand for the digit selection and that hand is then blocking you from seeing the screen.

I'd like to get my hands on one long enough to try this, but doubt anyone in my area has one on display - I'll try West Marine. If anyone else has operated the M-803 in ham bands I'd like to hear their opinion of the user interface. To me it seems ergonomically unsound (to put it politely).

The M-802 has a 3 step selectable filter bandwidth for CW. I don't see any such filter in the M-803 manual. I would have to use an external audio filter for CW with the M-803. Actually that is a better solution since the external filter bandwidth can be quickly changed with a hardware switch.
