Transmitters in bread pans
« on: December 17, 2017, 03:30:14 pm »

I was reading through the thread (linked below) and didn't want to derail the experiment in progress, but can someone explain the practice of putting transmitters in bread pans? Links welcome!

Thanks for that.  I was so concerned about cluttering up the other thread with my lack of knowledge on the subject, I presumed that link was specifically and only addressing the battery anomaly that was the subject of the thread.

I did my own testing with 6 transmitters within about 10' of the receiver antennas and watched the receivers that were turned on but did not have a transmitter associated with them.
Watched as the RF showing meters on the open receivers dropped away to nothing as the transmitters were put in the trays.
As others have found out, it really works to reduce intermod problems with multiple transmitters in a relatively close space.
2 major mistakes I see all the time are...
1-transmitters on a table too close to receive antennas
2-transmitters that are lined up in a row on a table. (use the pans Luke...)

Hi Lee,

FWIW I don't think you would have cluttered up the thread due to your lack of knowledge, because I don't know anything either and am asking questions to try to learn.

I appreciate that.  I started this thread so that those of who know nothing about the technique could get sufficiently caught up and make intelligent posts in the other thread!

Then I just realized you're the guy doing the testing!

Thanks, Dan, those are nicely behaved. The ones I'm using in the experiment are quite nasty, and I'll post some pics in the other thread later this afternoon showing just how nasty they are. Still, they are going to serve a purpose in my world and I'm happy to have them.

Those are at 10mw.  These are 4 mics in close proximity at 50 mw
