Have to agree with Al. Find a HAM. We are used to making things work or finding out just why they don't. My nickel is on the final section of the old rig. What you have described is common in older radios; they work good when you first turn them on and gradually lose power as they warm up. The good/bad thing about transistorized final sections is that they either work or don't. Regardless of what name is on it; it will eventually die. Bottom line: Power, ground, antenna connections; after that, you're into the box.

Transponder cable needs to be RG400 if you're replacing any component. Your avionics guy probably had a boat payment overdue. Guys and gals, remember that electricity is logical. I can't believe the time and effort spent on this radio problem, but applaud the efforts of all involved. What it's going to boil down to is a few things. Corroded grounds for the antenna, bad antenna wire/connections or a bad radio. If the ground has high resistance, it could be pushing the finals on that old radio causing them to fail intermittently. Connecting the ICOM to the ship's antenna should have shown that, as would a simple OHM meter. My vote is the old radio, but I'm a heck of a long way away to do any troubleshooting. Don't forget that if you know anyone who has an amateur radio license, he can probably advise you better than most avionics shops, but he's not allowed to admit it or charge you for it. JRC's do well on EBay. I'm happy with my KX99 after going through a bout similar to what you did with the Nip radios.

The coaxial I had installed in the plane when I bought it was no longer "LEGAL" as determined by something federal, Maybe he said FCC, maybe FAA. I was thinking big bucks instead of listening. It sounded a little like the mechanic at the tire shop asking my daughter when was the last time she replaced the air in her tires, but it was not too expensive to replace the coaxial cable and connectors. It did make a difference and I have never heard anyone tell me my radio was breaking up since then. As for the handheld. I bought a JRC four years ago, had to send it back twice because the first one overheated and did not work, the second one did not overheat but it did not transmit either, the third one worked OK but the plugs for the headset had to be replaced twice due to poor quality, I finally bought some good ones and replaced them myself. The plug for the battery charger broke several times. poor quality again. three batteries replaced due to the charger plug. finally I bought the regular battery case and I am sure I can't depend on it. The 25 year old handhelds that are still around were made a lot sturdier and if I can find a replacement rechargeable battery for mine I will throw the JRC into the dark corner of the hangar.
