This problem is recognized by the manufacturer. Icom will fix this, but the unit needs to be shipped to the company. There's a lengthy turn-around time.
In the meanwhile, cut back on power, using medium or low.

FYI: The 802 is sensitive about tuning. Icom has a hardware fix. Box up the radio and send it to the company and it will be fixed at no cost. (C_Language)
Contact the company before sending the radio.

Query: How to unlock the pre-programmed frequencies?
Turn off the power, then while simultaneously holding down the "2" "Mode" and "TX" keys, turn on the power again.

Create a batch file to eliminate the ini file. This takes a bit of work.
Removing the corrupted ini files works; the program will generate a new one.
Turn off Cruise E-mail before shutting down the radio because Cruise E-mail will hang otherwise.

Issue: There's audio distortion when the Pactor modem is attached.
It's a common problem. The modem needs to be turned off.
If the problem continues with modem off, add ferrites on the cable.

Query: What is the proper service cycle for injectors?
If the engine starts and runs right, leave them alone.

Issue: Injectors have a very short life.
Use fuel additive Stanadyne. (Trumpeter)
Longevity varies with use and fuel source.

Issue: I used SeaFoam, following directions on the can, and had no results at all. No smoke, etc.

Make one out of a penny. Do a little sanding and trimming. Anneal with a quick quench.
Check the rubber seal that's there to block debris.
Check to make sure the gaskets haven't been doubled up from the past.

Query: Can injector testing be done by checking the spray pattern?
Stand back! Spray causes blood poisoning and could permanently blind. Use a pro service.

Clean and service them regularly even if the engine seems fine.
Especially check for looseness. Pros recommend doing this every 900 hours. (Salty Paws)

Query: Does anyone have any info about KISS-SSB?
The KISS system is a set of pre-cut copper wire radials to be used as half of a dipole antenna (counterpoise).
Read the KISS thread on the Cruiser's Forum.
You can make your own. Forum Discussion.
A handy calculator for radial lengths, if you decide to make your own.
Make your own with inexpensive speaker wire. Instructions on Cruiser's Forum.

Query: Would adding KISS to the existing ground plane make it work better?
No. They work in two different ways.

Kiss SSB Grounding System is self-contained and recommended by Icom. (Barefootin)

Something I learned from a friend with a GB trawler. He was installing his SSB and had a dilemma about how to get a satisfactory ground plane when his tuner was located up in the fly bridge close to the antenna. He bought the KISS system and spoke with the supplier who said the KISS did not have to lie against the hull but could be laid out under the dash on the fly bridge, thus eliminating the need to put anything in the bilge. (Barefootin)
