Re: VHF MTR2000 Poor Receive Performance
From this post: /g/repeater-builder/message/195129 I'm not sure Jared has the capability to accurately measure RL. This is especially true if the directional coupler he is using as

Re: VHF MTR2000 Poor Receive Performance
* My calculations say injecting the signal into antenna port of the duplexer with the transmit side terminated, * the repeater should take 0.41uV or -114dBm to reach 12DB SINAD assuming the repeater

Re: VHF MTR2000 Poor Receive Performance
I figured I probably am chasing my tail on the repeater end. But a trip to the dealer would make me feel better. My calculations say injecting the signal into antenna port of the duplexer with the

Re: VHF MTR2000 Poor Receive Performance
You may be chasing your tail.? Signal generators/service monitors are not all that accurate.? ?I was playing around with a couple of HP 8924c and an IFR 1200s.? I noticed that even after about 10

Jim, I thought I had copied your message in my response, but I guess not.? This is what you sent.? I'm not sure how it will open the path for the wide band audio connections via pins 9 & 34 of the

Re: VHF MTR2000 Poor Receive Performance
If I get what you¡¯re saying, I already ran those results. I inputted a signal through the antenna port on the duplexer and into the receiver through the duplexer. I had the transmitter side of the

Re: Harris portable radio batteries
We used to run Honeywell lithium polymer batteries on our XTS 5000s. Great batteries! They lasted 20+ hours with moderate transmit and near constant receive activity in talkgroup scan on a busy P25

Re: Motorola MTR 2000 UHF repeater.
This can also occur if you have removed one of the option cards or have made a change in the codeplug that would need one of the option cards to function. Read the codeplug and as Millin has said find

Re: Motorola MTR 2000 UHF repeater.
Glenn.. unplug the repeater, read the repeater to see where the error is located in the software .. sometimes the blinking red light indicates a power bump or a shot PA. So read the repeater clear

Re: VHF MTR2000 Poor Receive Performance
Jared.. disconnect the tx side and terminate it into a 50 ohm dummy load. Terminate the high side of the duplexer..inject a signal from the antenna port of duplexer and see what you get. Any

Motorola MTR 2000 UHF repeater.
I have a MTR 2000, and the Power light is flashing. Searching the internet, I found that it is in service mode. What do I need to do to get it out of Service Mode? Thanks for your help. Butch KE7FEL

Re: VHF MTR2000 Poor Receive Performance
It would appear that I have 2 issues resulting in the over 3 db down which probably explains my issue. So I guess that¡¯s what I mean when it¡¯s ¡°deaf¡±. I must be horribly messing up my MTR

Re: VHF MTR2000 Poor Receive Performance
FWIW, it¡¯s probably easier if you state your measurements in dB instead of uV. 0.53 uV = -112.5 dBm 0.40 uV = -114.9 dBm So, you¡¯re losing 2.4 dB in your duplexer, not the 1.3 dB you stated

Re: VHF MTR2000 Poor Receive Performance
So I injected signal into the antenna port of the duplexer and hooked the receiver to the duplexer without the TX hooked up. It took 0.53 microvolts to maintain 12DB SINAD. But the thing is, when I
