Found an enclosure box that I think might work. A bit on the big side, but then again so are the joystick and button. Box isn't quite deep enough to put the button on top, so I think maybe on the side as a finger button.
The joystick is very clicky
Well, I'm getting all 0s out, but honestly I don't know if that's because I'm not reading the EPROM properly, or if it really does have all 0s in it. Probably the former.
Wired up a 9V connector to the radio and powered it with 8 AA NiCad batteries in battery holder. Radio seems to transmit ok. Wasn't hearing anything on receive, and the squelch dial didn't seem to work all that well.
Clipped on a 12V battery pack to the power leads, turned it on and heard some static, so it sounds like the radio still works. Will see if I can manage to find another 9.6V battery pack to replace the missing one and figure out a charging solution.
A lone integrated circuit just has a sticker label saying NIS-103. Guessing maybe this takes care of producing the DTMF codes from the number pad on the front.
2 circuit boards inside. Guessing the one with the wire coils and variable inductors handles the RF side of things, and the other board handles the controls.
The battery pack was removed (probably because it went bad) and a car power adapter was wired in its place. Based on other pictures of the Tempo S1 I've seen online, the telescoping antenna was replaced with a BNC connector, and the earphone/antenna jacks have been replaced.
A Tempo S1 handheld 2m FM transceiver. This one's seen some use, and a few mods. #hamradio
Pretty good ARRL Field Day in the back yard yesterday. Fun casual time on the air.
