Hello,
Just another update on my Philco remote control. I did flatten the Tenite dial and it's no longer binding. I figured the best way to see if the remote was actually sending out a signal was to wrap a few turns of wire around the antenna and connect a scope. I set the remote to put out a constant signal by holding the button down. I had to tweak the variable capacitor just a bit to get the remote to generate a 383KHz signal (that's what the receiver is set to). I attached a picture of the signal. Nice clean sine wave! I also just turned the dial all the way to the stop and took a video of the output which shows the remote pulses. I'm not sure I'm allowed to post a video, it's about 100Mb. If a moderator could let me know if it's okay, I would appreciate it. I still need to replace the wax capacitor, but it is still working for the time being. Now I can start on the chassis.
Thanks!
Rich
