I have an P1755A suitcase AVA, will a AS VHF model II work in it? When I plug the radio in all I get is the charging indicator, when I push the PTT you can hear a soft click but nothing else. Any assistance would be appreciated.

Ok another question on the rocky learning curve. I have a Astro Saber and a Astro Spectra both IMBE P25 that I cannot get to talk to each other; I was wondering if there is a white paper on the correct settings to make them talk. The Spectra will talk to the Saber fine; however the Saber won't talk ...

All is now well in Spectra land.

I think I've done all the steps; I created the scan list, select a button in the head setup and wrote the new info to the radio with no errors; still no scan.

radioconsult

I'm getting my feet wet and having some difficulty in getting my radio to scan, I've setup a scan group and enable a key on the head but no joy. Is scan normally incorporated in the radio or is it a flash enabled feature? BTW using CPS.

I have the opportunity to get a VHF Astro Saber; but I'm not sure if it will do P25. I've looked at the CPS and the two options under conventional are analog and Astro Digital. The following are found when performing the self test: Flash 100004-000000-4, Ro 05.00.02 and DSP 106.04.09, 512k. Based up...

Some of the early paging systems back in the 50's & 60's, were AM modulated and operated in the low band (35Mhz). The receivers were mostly superegen types the newer ones were superhet. They were carrier squelch with an off-on volume. The transmitter would remain keyed up all the time. The"...

Try APRS Plus, you can download the eval version and play with it. It works really well with Street Atlas and can display fixed stations and mobiles on the map.

Today (Tuesday 12/9) on ABC Nightly New during one of the war stories out of Iraq a US soldier was shown taking his mil FRS off his webbing and talking on it. Sure looked like an FRS including the jazzy color scheme.

I suggest that you do a search on the G5RV and read up on the theory. The ladder line is actually part of the antenna system and should be laid out in a line and not folded. The true G5RV design does not use a balun at the junction of the coax and ladder line. On my G5RV I wound a RF choke consistin...

Check the FCC rules for the Taxicab Radio Service. My recollection is that repeaters are not allowed, except with a specific rule waiver, which may bet hard to get. Look at their license and see what the base station class is, FBsomething. The actual mechanics of a repeater may be the easiest part. RC

Haven't changed the programming in about 2 years, radio has operated fine until today. Get the fail in the 462., 451, and 444 bands. The fail rate is faster in 444 and slower in 451.

My UHF Spectra (mid power) today started flashing a fail 001, about every 5 seconds. I've done a power reset but still flashes. Any ideas? BTW its used as a control station, indoors on an Astron supply.

Search the FCC database at http://svartifoss2.fcc.gov/reports/index.cfm
You cab search by any number of criteria, you will find that frequency is licensed in the IG service. There are several pages of assignments throughtout Texas listed.

Downtilt antennas are used a lot in cellular and PCS applications.

I'll ad my opinion based upon many years of expierence. A well maintained low band system will out perform a VHF or UHF system, either simplex or repeater. This means good mobile antennas installed in the proper place on the vehicle, no "L" brackets, or antennas mounted to luggage racks, l...

Intermod is a often mis-used term. First you need to determine what the exact frequency of the paging transmitter is. It may be LB, VHF, UHF or 931 MHz. Then work backwards from your most interfered with receiver and determine if there is a numeric mix, i.e. 2A-B, etc. IM is a mixture of several dis...

Back in the good old days, i.e., radios that glowed in the dark and had mechanical rx-tx relays you could do multiple radios in the same band with one antenna and still keep the smoke in the radios. You would connect the antenna to the ant terminal on the first radio, then connect a jumper from the ...
