Re: [Repeater-Builder] Tait 2015?
Anyone know if these radios can be used even in simplex mode? (on 220) Thanks, Robert (of course within the ham band ;-) If you're talking about the LTR trunking variety on 220 MHz, they will TX and RX in the ham bands after much twiddling with the programming software. However... they're narrowbanded (low deviation) and the receiver I tested was very very deaf in the ham band. They would NOT receive and transmit on a standard split or set up talkaround (simplex) correctly. Would have worked to have one for TX and one for RX as a repeater, but you couldn't use them as mobiles, etc. And with the narrowband deviation they'd have sounded bad. They get horrendously hot on TX, didn't seem to matter if the power was set higher or lower. They're just a hot-running radio with a very small heat-sink. The UHF non-LTR trunking variety also does this. Perhaps the receive sensitivty could have been remedied, if I could find any tuning information about them, but I screwed up the receiver I was playing with on the workbench while I was digging for a COS circuit and dropped a tool. I never went back to messing with them. That receiver unit was dead as a doornail after that incident (zaaap... oops, let the smoke out!) and I only had two. Both the dead and the live one are sitting here in storage if anyone wants to mess with them. Oh yeah, the BNC connector for RF is also a pain, but they do usually have a punch-out for a DB-9 accessory port which would make a good place to bring out COS/PTT, etc. Nate WY0X Yahoo!
