I thought I'd share this as it may save some folks some money if you have a flaky Davis Transmitter. I have a old Davis wireless VP2 (6152) with two transmitters, the ISS transmitter and a separate 6332 transmitter for my anemometer/wind direction. The transmissions on both of them had become spotty over the last few months. I replaced the batteries but no luck.
I removed the plastic cover in the transmitter housing and found that the supercapaciter on the 6332 had leaked and the one on my ISS looked iffy. I ordered two new capaciters from digikey (2085-TPL-10/10X30F-ND). I also found the solder to one leg of the battery holder on my ISS was loose. I replaced the caps and fixed the battery holder. So for less that $5 in parts I was able to get both operational again!
Interestly enough I think the bad cap on the 6332 was causing it to interfere with my 900mhz headset as it was having range issues while all this was happening. Once I replaced the capacitor the headset went back to it's full range.. Weird.
