What I would like to do is fool the station into thinking the 350w PA is still there, so I can run just the 20w driver to push a new Creshend rf amp. Does anyone know how to jumper the PA sense line?

loband

Anybody have a working 350w PA deck they want to sell?

loband

What's the point of buying a 110w radio? It's knowing you are buying the best and if they still can't hear you, well you done all you could. No second guessing.

loband

The point of the can antennas is not the look but they are rugged. Here in New England when clearing snow off the roof or going thru a carwash the antennas won't be damaged and the radiation pattern is ideal for repeaters. The 6" 1/4 wave will bend and stay bent. And the Pctel UHF is wide band ...

loband

We ended up going with Stico splitters so we can use a 1/4 wave wide band Pctel for VHF and can style antennas for UHF & 7/800.

IMHO, the single RF connection is a bad design. Should have the option of at least 2 if not 3 antenna ports on the radio. Users in public safety want low profile antennas....not some big ugly soda can with a whip (PCTEL) or ugly bigger can with center load whip (Laird) . If you use a splitter the lo...

Thanks !!!!!

Does anyone know what type of antenna connector is on the APX 8500 mobile? Never seen it before, some type of quick connect. We were told by a moto shop tech that it is a QRX....never heard of it nor can google find it. I would like to find an adapter to attach test cables and other antennas.

loband

Yes it is a multiband band NMO from PCTEL.

loband

Kevin, That would be great, let me know what you find.

CoM, if you have the information how to bypass to trick the station to run with out the PA that would be great!

Thanks,
Rob

Any body have a good working 350w PA for sale?

We had the same issues with one. Started out intermittently going into low power alarm and would self clear. Finally after a year of this it quit altogether and now shows PA Fail.

loband

SlimBob you answered your own question.... "SlimBob wrote:So the final answer is ERP and antenna pattern. That's why you buy a 110W radio. Coverage, plain and simple." You won't ever see me driving a Prius....only big block V8 power.

loband

High power is needed for some situations. We run mountain top 350w vhf P25 repeaters, TXRX .6db loss duplexers, preselectors and ARR preamps, 6db omni 4 dipole antennas fed with 7/8 heliax, no run is over 150'. Mobiles are 110w APX7500, XTL5000 or Astro Spectras and 1/4wave roof top antennas. Yes th...

loband

Ok, ya'll made me check....All my pagers are UL, Minitor 2, Advisor Gold, BPR etc. The Nextels were FM but my current phone is UL. All the portables from the MT500 up to the APX are FM. As for the green dot question on other threads...it was for easy I.S. identification before going in a hazmat loca...

loband

On the UHF M6 machines we set the squelch to the loose setting....works great.

loband

You would also need the xtal tuning coil for the second freq if there is not one there already. Most likely it is not if it was a factory single channel. After the xtal and coil are installed, you would need to tune it on frequency with a communication service monitor.

loband

I have a 25w vhf Quantar I will trade for a high horse power Quantro. All one has to do is drive it here.

loband

Why bother to own a high horse power machine only to run it at low power.....it brings a tear to my eye to even think about it......I'll give it a nice air conditiond home and run it at a cool 300watts. Hehe.

loband

Well that would be nice if it does, then I'll have the best of both worlds. But because there are times when a portable is too bulky to carry around, the compact M6 with vibrate and voice storage are a nice features to have. And to receive Astro I programmed a channel in the M6 for the VRS when I'm ...

loband

Well I couldn't hold my breath any longer....I bought a M6. Works great.

loband

I would tend to agree with you but the APX is well within spec. This was a real world test, in a vehicle, on the extreme fringe of the system, the APX was in scan sitting in the console cup holder, pager up on the dash board. The pager alerted then recorded white noise with barely audible speech in ...

loband

I just took deleivery of a UHF M6 and it receives better than an APX. The pager breaks squelch and alerts and is very noisy where the APX is silent.

loband

Yep next Qtr '14 then in July it will be the next Qtr. Like the sign in a bar....Free Beer Tomorrow

loband

I have been promised QCII from Moto when we bought the radios in 4/11 been waiting ever since....same old story...next qtr, next qtr.....

loband

Because our town dispatches QCII analog then all comms are P25 and I need to answer the page verbally. I carry an APX7000 and a phone everywhere, why add a third devise?

loband

So let me get this straight...they are going to add Motrbo and QCII to the APX7000?

loband

I may have for sale a legit with all tags...APX7500 UHF R1 & 7/800 05 head mid power currently flashed for conventional analog. Any interest?

loband

Escomm, As a Moto dealer can you shed any light on the situation? Can a VRS be incorporated with the APX dual band radio? I don't see how it is possible.

loband

Yep and for the cost of a DVRS you can by two APX mobiles.....The SVR 200 is a great deal and works great too. I like it better than the VRS750 we have in the fleet. The only thing I miss is the remote channel select.

loband

Did you get the VRS750 to work?
We checked with Moto and were told at the time it was not compatable, only the new DVRS is, so we went with Pyramid 200 series and they work great, even does in-band UHF repeat. Our APX7500s are VHF/UHF.

loband

Update. New replacement head arrived and the problems are completely solved. We will be replacing our other 05 APX heads as well. Seems to be a problem will older heads. I am very impressed it turned the 7500 into a "new" radio. RX sensitivity is hot and speaker audio louder. Bravo to Moto...

loband

Yes it could be. I am working with Moto engineers to solve this. Seems to effect other APX7500 05 as well. Something in the Audio Amp circuit. Most users would probably not notice anything is wrong. But working with weaker signals it is very noticable. The test is very easy to do. 1: Set the APX 750...

loband

Update.....waiting for a new replacement control head from Moto to see if it takes care of the problem.

loband

Ok after much experimentation and reading the service manual I think the problem maybe solved or at least identified. The yellow ignition sense wire is radiating the vhf band spur from the 05 head micro processor. It's access of wire was originally coiled up, it is now shortened. While receiving a w...

loband

All your suggestions are appreciated. Ok more trial and error came up with more insight to the problem. The 05 control head appears to be radiating strong spurs. Here is what it is doing.... If you take a portable in this case an APX7000 and set it to receive a strong vhf broadcast and the APX7500 i...

loband

Escomm, How would you like for us to check the "infrastructure"? It is all signals received on VHF. Changed the radio box and control head with an XTL and the problem is gone. So...common sense the problem is with the APX. Roof top NMO antennas are PCTEL no tune wide band and are less than...

loband

Yes both antennas test fine. Not fixed infrastructure related. It is all vhf systems including federal, local and weather freqs. As I said put XTL5000 or A/S is the same vehicles in place of the APX and antennas and big difference in vhf receive. We have a large fleet and only these two APXs and we ...

We have 2 APX7500 mobiles installed in 2 different vehicles. These are 110watt VHF/UHF R1 with 05 heads and RX Preamp option. Both radios are deaf on VHF compaired to Astro Spectra or XTL5000. The latter will hear a readable signal were the APX is silent. Or a noisey signal where the latter hear cle...

To keep th battery charged I run a Honda 2kw suitcase generator to the on board installed battery charger in the truck. Our other trucks run...

Hi All, does anyone know what the rf power output of your SVRs are set to? I know the range is 250mw to 2w. Motorola highly recomends setting no more power out than 275-300mw and a 1/4 wave antenna. Any higher power and the VRS & SVR will out talk a 4w portable according to Moto due to the tight...

loband

The APX 7000 & the APX 7500 are single band - you pay more for the dual band option as with any other options.

loband

What is the part number?

loband

Ver. 3.0 is current however it will not program the ALE that requires another software program but you can perform all programing from the radio control head without software. Elbit is now the current manufature and suports all or most models. Dave at Royal Communications in CA can help you with par...

Oh another thing, use at least 1/2" wide ground braid never a round wire for the grounds!!!! Ground both the coupler and the ground stud on the Micom to the car chassis. Make sure the high voltage lead from the coupler to the ball stud is less than 12". Short as possible and a 12g wire is ...

First off the Wima antenna is well worth the money. That is what I run. The next "affordable" option would be the SGC-230 and a heavy duty ball & spring mount with a fiberglass hamstick tuned for 30 or 40 meters or lower. This would give the SGC a tuning range of 1.6-30. The 16' Mobat ...

I have GPS in our APX7000 radios. They need to be orderd with the packet data and GPS flash. Then the option will show in the CPS. You can have the GPS always on or user selectable from the radio menu. We do not send GPS data over the air as the equipment required to interface at the console was quo...

Yes, I know after taking a closer look at them.
