I deployed the W1HFN fox today in the Mill Hill conservation land off Mill Road in Littleton. Frequency is 146.565 with a voice ID every 30 seconds.
When I recovered it last time, the TX was keying up for 2 seconds then shutting down. I assumed a dead battery. When I got it home and recharged the battery, same symptoms. Wrong assumption. Turns out water had leaked into the case and landed on the TX PC board. It reacted with something and left a conductive goo all over the traces. Scrubbed it off with alcohol and toothbrush, then dried with a hair dryer. Worked OK, but had lost its audio message.
Reprogrammed the audio and we’re off to the races.
