Thank you, that got me headed down the right road, I believe.

I have a small fleet of XTS-2500's ( H46KDD9PW5BN ) running analog conventional right now. One of our nearby agencies has gone to P25 digital. I don't see any obvious way in Astro 25 Portable CPS r19.01 to enable one channel for P25 Digital.

Does all that take place under 'ASTRO Systems' instead of ...

I am trying to learn more about our City's VHF radio systems (HT-1000's, Spectra's, Quantars), and I need some good suggestions for books. I believe we are starting to outgrow some of our infrastructure geographically and I'd like to be able to ask vendors some smart questions.

When someone ...

One common solution I've seen is to put a rubber band around the volume and squelch knobs, wrapped a few times (tight is NOT the goal). The rubber band creates additional friction against accidental rotation.

I bought a portable scanner and did some testing. I don't find any Cable TV leakage in our problem areas of town, but I do get some occasional blasts from a paging service.

I ferrited everything I installed at each end of the each wire for some benefit.

I went over the installation with an HT-1000 ...

Having installed hundreds of Spectras and Syntors in Crown Vics and other vehicles ...



Thank you for your extensive list of problem areas. I'd say I now have several weeks of things to chase down. I never knew there were so many wrong ways to install a radio system.

As I make progress, I'll ...

Another area you might be caught up in is if they have mobile computers in the car.

One other issue that may effect you is the car digital clock.

You could also be unlucky and have the car computer module spraying trash on or near your operating frequency.

If you have cable TV in your area ...

You're probably wiring the remote trigger wire to actuate the recorder when they hit the light bar if you're using it. (most I've seen are set up this way).

Actually, what I'm trying to do with this installation is run the camera 24x7, no triggers, no user intervention. The interior of ...

That's rather fortunate, but a bit disarming -- you've both dated yourself and not dated yourself.


'Dated' covers it well! Most of my experience involved fixed base in the 70's at HF. Although I read up on RFI/EMI back then those books have long since gone away and I'd hope the technology has ...

What the brand name of the DVR's. Our agency is looking at new in car video systems.

Jim, K8COP

These are Aegison 6010M 's. The nice thing about them is they have a streaming server that can archive the data automatically. There are plenty of systems that let you collect data, but once you have ...

It is uncommon...the problem is likely not the radio.

Normally, the Spectra or X9000 squelch could be between 5-8 depending on local conditions. Mine breaks squelch at 2-3, and I leave it at 6.


WITHOUT the DVR , our squelch must be at 10-12 in normal use, and I was trying to figure out if ...

So, having the squelch level at 10-12 is not uncommon for a Spectra in a Crown Vic (ignoring the DVR issue) ?

I work in an IT capacity and am installing digital video recorders in 2005 Crown Vics. The CV's have 16ch 100w Spectra's (circa 1990) and 100w amps in the trunk, at 154Mz. I am running into noise problems and would like some opinions on what 'good' looks like.

The radios have been 'ok' for 10 ...
