I understand the issues surrounding the nmh vs li-ion charging schemes. Thank you both for your input.?


I was hoping for a response from someone with up to date knowledge of the Harris product line and could say something like ¡°Yeah you need one of these and here is a PN and a picture so you know what it looks like.¡±

If there are any Harris guys out there, I am still looking for someone who knows something about jaguar chargers. ?Anyone? ?Buhler? ?

Kevin.. head to radio resources and there is a section in the forum under Harris.. there are alot of users in there that plays with this equipment

I miss Ghost for a lot of things.

One option is Clonezilla.? Free.? Text interface over the Linux-based code.


Re: Somewhat OT... imaging a hard drive...

 

Clonezilla if you want something free but it's CLi driven, Acronis True Image (if it's still around) if you don't mind paying for it as it has a nice 'pointy-clickey' interface...

Thanks for the great information, even thought the MTR 2000 has battery backup, I am sure it was a power bump. I read the repeater and everything was good so I re-programmed it and it is working fine now. Thanks for all of the great information. 73's Butch, KE7FEL

I'm not sure Jared has the capability to accurately measure RL. This is
especially true if the directional coupler he is using as limited
directionality.

There is also reference to readjusting the tuning after the resonators
were coupled back together.? I realize that the geometry of the Tee
connectors on the factory harness isn't able to be duplicated by a
standard F-M-F Tee, but depending on how far the resonator was 'tweaked'
after its initial tuning, it might not be right.? I wish I was closer to
him - that's a great duplexer, but I still maintain it's impossible to
tune (correctly) without a VNA.? Heck - even a Nano VNA or other USB
based VNA would be better than a directional coupler with unknown
directivity.? One 'bad' thing though with these cheaper VNA's is the
inability to set the stimulus power level, and most of them use -10dBm
or so. While that's not a concern with filter tuning, it'll overload
most receivers and as Jeff mentions, overload of the first active stage
will result in erroneous RL measurements.

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 minutes of warming up one and or both of them took a db more of output to give the same measurement .??

In real use most of the time a db or so will seldom be noticed.

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 duplexer terminated into a dummy load. It took 0.53uV or -112.5dBm to maintain 12DB SINAD through the duplexer. But the oddity is that I took the cable from the signal generator and hooked it directly to the repeater and it took 0.4uV to make 12DB SINAD. The day before I tested the repeater at 0.35uV directly connected to the service monitor.

Re: QUANTAR VHF Audio Interface...

 

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 50-pin Telco connector, but I'll figure it out and give it a try.? As I said earlier, I do have the RSSI software and it does talk to my QUANTAR via his front panel spigot.

Thanks,
