In this video I demonstrate how to do a preventative maintenance check on a Midland Basetech III vhf repeater using a Motorola R2600 communications service monitor. This involves transmitter checks for power out, frequency error, deviation and repeat audio. The receiver is tested for 12dB sinad, freq error, tight squelch, site desense and local desense. The duplexer is tested for pass and reject on both sides.

Nice presentation on repeater testing. Was it a wide band repeater or narrow band? 2.5khz or 5khz deviation? Thanks for taking the time for these videos.

Thanks. That was narrowband 2.5khz. Will do a P25 version soon.

Great video. Where can I purchase that 1:1 isolation transformer that you are using in your SINAD test? Thank you.

Thanks. The one I was using was from an old IFR service monitor. I can't find anything like it online. If I had to make my own I might use a Valcom VMT-2 with some coax pigtails. www.amazon.com/Valcom-600-Ohm-Isolation-Transformer/dp/B00OZDR1KA/ref=asc_df_B00OZDR1KA/?tag=hyprod-20&linkCode=df0&hvadid=642112814556&hvpos=&hvnetw=g&hvrand=1854126406178952501&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1015150&hvtargid=pla-2003424720607&psc=1&gclid=CjwKCAjwvfmoBhAwEiwAG2tqzKrxOPCo5eBGW5lbjIJbAoCwsw5YFXl-MnvZr1mLPbb2TzZ2Lv5_5xoCfAYQAvD_BwE
