I have a NXR810 on my 440 pair. And one on my 470 business pair. At first, the 470 would lock up in what seemed like the test mode. Stuck in TX with 800khz tone. Only resolution, shut down, power back up. then I placed my 440 repeater, also NXR810 at same site. Same issue. Would occasionally lock up in tx with 800khz tone. We did check of all frequencies for harmonics. nothing close.
Firmware on both is latest and greatest. Was doing voltage check and noticed when either would tx voltage would drop to 117 volts. So I spend $500 for a really good UPS. After one week, my 440 tonight locked up for 3 seconds, and cleared and was OK. I threw my call sign out after about 10 minutes, same thing. locked up for 3-4 seconds and cleared. Bout 10 minutes later after I got another beer, threw my call out and now stuck in tx for about an hour. The 470 NXR810 is OK and it is being used a little.
Any thoughts?? We thought maybe, it was voltage sensitive. Both got 20 amp power supplies, which are brand new. They are an same electric circuit, but maybe the circuit got other "dirty"electronics on it we don't know about??
Thanks.
