It may be working OK. Just trouble-shot an 802 on Friday and found a couple of things which may be of help.
1. Be sure your power level is set to high. The one I worked on was set to low power
2. Older 802s have a "clipping" problem, for which Icom
has issued a service
bulletin. This tends to cut down/off the transmit power whenever an SWR condition is sensed that the transmitter doesn't like. The factory can fix this, but you've gotta send the radio
to Bellevue, WA for service
3. The best way to tell if your radio
is transmitting is to connect a good power/SWR meter to it's output, i.e., between the radio and the tuner. Better, if you have one available, connect a dummy load to the wattmeter which bypasses the tuner/antenna altogether. This will tell you how well the radio is transmitting on any chosen band.
4. The tuner may not click if it's already tuned. Have someone listen carefully at the tuner, change bands, and push the tune button. See if any clicks are heard.
5. Be sure to check all connections -- antenna
and ground and power -- very carefully.
6. Ground plates IMHO are pretty worthless, especially after a few months in the Caribbean
. Better to build an RF ground system which isn't dependent on them. The simplest way is via a wide copper strip from the tuner ground lug to the nearest bronze thru hull
7. You don't need to connect the RF ground to the 802 itself. Often, doing so just creates problems (ground loops).
