It does. I also have speaker amplifiers built into some of my Sinad Meters plus the trusty tribble size (9V battery powered) type portable speaker amp from Radio Shaft (Shack).My main concern about local speaker audio and squelch settings is keeping those magic fingers off the front panel controls, added distortion of some of the circuit (ie the LM-380). Plus the current requirements of the audio power amp section at solar and limited power sites. Once the repeater is done and installed at the site, local speaker audio should be off anyway. I see. It wasn't that you weren't using a speaker to test for desense, you simply don't include one or a way to connect one in every instance, and that's fine. I prefer to have a way of listening to my receiver with an available speaker. Like others, I have sites that have no room for a dedicated speaker to reside with the repeater. Many times I simply take my Micor speaker from my truck and use it on the repeater. I have it configured with an 1/8 inch plug on the end to connect to my Japanese mobile rig. All of my machines either have a dedicated speaker for monitoring or a 1/8 inch speaker jack for my speaker. Even my remote receiver sites that use Hamtronics receivers (R144's) have a speaker jack as I don't use the internal amp for anything other than the speaker. Kevin Custer Yahoo! Groups Links
