Title: Midland 75-785 Handheld Radio Drive Thru Modification Failure
Post by: merelyconfused on January 05, 2010, 05:32:30 PM
So here's the problem. I bought a 40 channel Midland 75-785 handheld transceiver and acquired a 6.5536 mhz crystal to swap into it. I opened the radio up, desoldered the old crystal, soldered the new one in, and I figured I was done. When I was putting the case back together, I accidentally pulled off a green wire that was coming from the speaker/diplay/mic pc board to, I think, a big solder mess that seems to connect to the external antenna. I soldered it back on, and closed the transceiver back up.
When I turned it on, everything seemed to be working fine, but absolutely no sound was coming through the speaker. The only way I could tell that it was on was by turning up the volume all the way and hearing that barely-perceptible whine. Moving the scquelch setting all the way to zero perhaps no static whatsoever. What could I have done? Was it a bad soldering job of the diode? That green mystery wire? Any help would be greatly appreciated.

Don't get me wrong, I'd really appreciate the help, but I have some reservations giving someone on this forum my phone number. Especially for a show where you guys prank call people.  ;D

If you are, however, being entirely honest, I genuinely apologize.

Well fuck me.

Haha.  Sorry!  You can solder the old crystal back in and resell it on Ebay.

You should send me your address and I'll give you a sticker and PLA media CD so I don't feel as bad.

hah ok. I do have to say, it's quite impressive that you guys are still getting people with that video after two years. It's the most convincing hoax I've ever seen on the internet. The encouraging comments posted everywhere by people from this forum really did the trick.

However, it is obvious that you guys actually did do this. Perhaps with the yaesu? If so, I'd love to set that up for real, if anyone if willing to help with that.  ;D

PLA, Good Job!

If you are still interested in the drive through hijack you can grab yourself something like a Baofeng uv-5r.  The Baofeng is a lot cheaper than the Yaesu radios that they used and come "wide open" so no frequency mods are needed.  It would also good idea to snag a dual band mag mount antenna and appropriate adapters.
