I know this thread is older than moon rocks but I'm trying to use this tool to generate a UCL I can import into APX radios and keep running into this error: UCL line 1 references undefined system '' of type I can't find any combination of system name, number, dashes, underscores, etc., that will mak...

Thanks for the replies guys. We don't use PL259, at all. That's what I meant by 'shoot on sight' I ordered the Cambridge part from Mouser and received Emerson Power CPL2591 parts, made in Taiwan. I guess we know who bought the Cambridge tooling for that part. Anyway, I'll try these and keep looking....

cablemonkey

Thanks for the ideas. I got excited for a minute when I saw the Cambridge line, but it would appear, much like Kings, that the part has been discontinued. We've tried Pasternack, RF industries, Amphenol, no-name offshore, and Emerson power. They all 'get the job done' but I'm looking for the highest...

Hi, I have to deal with a lot of marine VHF equipment, and now that King's / Winchester is no longer making UHF connectors, I'm having a hard time finding a quality replacement for those connectors. PL259 is shoot-on-sight in this shop and we've had mixed results with available products from the usu...

Thank you so much, that's exactly what I needed.

Is there an issue-3 of the manual planned? Issue-2 is really not good.

Hi,

Does anyone know how to route analogue FM demod audio to the handset?

The manual has lots of nice pictures on battery change procedures but very little actual substance for using the tool.

Any help appreciated.

Thanks,

-C.

My dealer just emailed to say that Aeroflex found one somewhere and is sending it to me, gratis! Gotta love service like that.

cablemonkey

I haven't used the latest version of the R8000, so take that into consideration. I'm very happy with the 3920, and so are my colleagues that have them. I think in this case, you're getting what you pay for.

Hi,

One of our 2975's has lost its little buddy, the AC25007 audio interface box. The pinout for the audio port on the test set is in the manual and it looks pretty straight forward. Has anyone got a schematic or even a photo of the inside of one of these handy?

Thanks,

-C.

Very solid product, small, flexible, easy to use and setup.

cablemonkey

And how do you find the manufacturers' web sites? There aren't really that many players in the game. MRT and Mobile Radio Resource equpiment buying guide issues can be pretty handy as well. Overall, I'd have to say that a good relationship with the local test equipment vendors works well for me.

cablemonkey

All the time. I listen to the news, mostly.

cablemonkey

Thanks for the reply Wowbagger. More than half of my work is at solar powered mountain top sites. No AC to be seen unless we bring an inverter or a genny to stuff some coulombs into the batteries. One more thing to pack into the helicopter. A high current DC connector on the back like a power pole w...

Those things are nothing but service call generators.

I've been wondering why there's no Volume or Squelch knob on the 3920?

cablemonkey

I never go that route. I usually call the local sales guys and ask them what's new, or talk to them at local trade shows. That, or go directly to manufacturers' web sites for the same thing. Sometimes I will call the sales guy up and say I need a "whatever" and ask them what they've got th...

The 3500 is a nice tool. I think it's like a swiss army knife - good at many things, but not really excelling at any of them. It will never replace a bench set, but for a rugged field-portable unit, you're not going to find anything as useful this side of a 1200S with a Return Loss Bridge ;) I looke...

Had a meeting with our moto rep today - these are available and shipping.

2W out, with a 4 hour battery life. :/

Good for overt-covert, or something, I guess.

We use cat5 with Vega desksets all the time. Works great.

cablemonkey

FYI I tried to buy the service manual for a tired 120B that we have here and learned that they are many hundreds of dollars. I can't find all the notes I made from the call but IIRC, the printed version was around $600 and the CDs weren't much cheaper.

cablemonkey

The wire feeding the fuse block is too small, or has some high-impedance connections in it. When you key the radio, you start drawing lots of current, which develops a voltage drop across the wire or bad connection. This drops your available volts too low, and the radio resets. I see this all the ti...

We have a mix of varying units in our shop. A couple of 2975s, a GD 2670B, and three 1200S battleaxes that just won't go down. We're shopping to replace the 1200s and have looked at the Aeroflex 3500 as a potential replacement. Sadly, it's not. Don't get me wrong, it's a great piece of gear, with so...

The local dealer has been saying "A few more months" for more than a year now. Apparently no one's even seen a working demo, just a mock up.

Has anyone seen one in the wild? Played with one?

cablemonkey

I've always hated those moto chrome nut antennas. (rust ring)

cablemonkey

Motoroloa service did the same thing to me, and after I whined long enough they sent me a copy of the latest CPS for the product for free. Along with a strongly worded suggestion that I should invest in a current CPS subscription.

cablemonkey

Total North or Northern Avcom can help you with this radio, assuming of course that it wasn't stolen from either of their rental fleets.

I'm hearing encrypted traffic on 143.220 near my shop here in Vancouver. I think it's likely the US border services guys as there's nothing in the Industry Canada database for that frequency. The MFID is 90 which is Ma M, but the crypto ALGID is 9F, which I can't find in any of the p25 documents I h...

The ALGID identifi es the encryption algorithm used in the P25 system. The ALGID is entered through a Key Management Facility or Key Loader when entering encryption keys.

Is there anything connected to the accessory conn. ? We have a bunch of 1550's on VEGA desk set interfaces and this is what they display when there's a problem with the cable or controller.

Check the acc. port config in the codeplug.

cablemonkey

You might want to check the bridge rectifier and see if it's shorted. I've seen this in a lot of cheapo supplies where this part is undersized and fails with heavy usage.

Let me guess what you have for test equipment.... Although technically it's: They took the cross town bus Don't throw trash on the street The shoes were black and brown.[/quote] That's what I thought too, but the manual says what I wrote.

Sti-Co makes a coupler and diplexer(aluminum box) that connects to the diplexer, tthe radio and to the coupler, and finally, to the radios and your broadcast antenna. I've got a few of these in service and they work quite well on a single frequency. The filter response is so sharp, you have to choo...

I've run mine just fine on a 9V. Nice and small to tuck into the programming kit.

I've tried to get our reps in the TR8 committee to raise that issue, and see if they would at least CONSIDER Speex before swallowing the latest DVSI creation, but.... It's more than that though, there's big money at stake. I was told at the Daniels factory that they have to pay a $250 licensing fee...

I've often wondered who got paid and how much to ensure that a proprietary codec got included in an open spec.

Maybe that's why it was such a hassle getting them to ship me a copy (as specified in our procurement contract).

I would strongly recommend you consider Comprod antennas instead of Bluewave as we recently undertook an expensive re-and-re of 9 failed 'extreme' duty Bluewave 210C2 style units from coastal mountaintop sites. Failure analysis on each one showed extensive corrosion from water ingress. Their constru...

Are you waiting long enough? My radio takes a few minutes to tranfer the codeplug to the computer and that's what it displays while it's working.

cablemonkey

I think I see my problem here...

cablemonkey

Ok thanks for that but the reason I asked is that I'm interested in enabling FPP on my XTS3000 and I see this topic about Rev 11 and I'm curious because I just received the version I indicated as the 'latest and greatest' from Ma M.

cablemonkey

How can I determine which version of CPS I have? In my 'about CPS' dlog I see R05.02.01 Is this Rev 5?
