If/when you do find out the operating range, Audio Technica made portable battery-powered receivers for mounting on a camera etc. You may be able to find a matching used one at a reasonable price - transmitters often get lost/damaged/stolen so the receivers are 'orphaned'. I'm not sure all of them have a headphone output but I believe most do.

A church in town uses a low power FM broadcast. Maybe your church has this?




Just a tip. This is the only part of the Amazon link you need.
Code:
https://www.amazon.com/4-Person-Enersound-Assistive-Listening-US-Based/dp/B0DRPT3F55

The rest of that is actually tracking crap.

Just thought I'd let you and others know as most don't. eBay does the same thing. They have a webpage about their tracking links...

In the 1990's in western Minnesota, every Sunday morning the troopers could listen to a church service over the local MSP repeater. It seemed the 72/75 MHZ link for the repeater matched the church's wireless mike system. Never could figure how it broke through the link's PL tone decode! "Everyone lay your hands on the dash for the final blessing and rotate your reds for an amen!"

...

It is easy to understand how this happened. When the MSP link (72/75 MHz were used by police etc. for links rather than as repeaters to the mobile units), was active, it was able to ride in on the PL tone provided by the wireless microphone. Note that thing having PL on their receive *do not generally require continuous reception* of the PL so another signal can ride in on some other transmissions PL. This is so they repeater does not drop put at every loss of PL. This is not an uncommon problem on repeaters having interference even thought they have PL on their receive side. Sometime repeater users think someone is jamming them because the interfering signal only appears when someone uses the repeater. The truth is the interference was constantly there, but was unable to key the repeater until someone else provided the PL.

Just an update. I wasn’t able to find out the frequency of the lapel mic. The receiver only displays a channel number. However, I did find out the church had a in ear monitor system that was already installed but wasn’t being used. We got it fired up and I gave my wife the receiver. It worked great. I suggested getting more receivers but the company, Xtuga, has backpack receivers with different frequency ranges. Where the problem lies is the frequency range of the church system, 572-603.5mhz, has been discontinued. I was able to locate two of the receivers on other sites and purchased two. They were about $40 each. I am going to donate one to the church and keep one for my wife. That will give the church two they can offer to let other people with impaired hearing to use

B.S.
