Good afternoon all, recently found a XG-75 for fifty dollars, kind of knowing that Harris radios are typically expensive and on the higher end (coming from a Kenwood standpoint) I bought the radio but would like help identifying its operating bands. The full model number is EVXG -PB78B, I would...

I work for a school district and am looking for some advice on a recurring coverage issue. Our system uses two Motorola SLR 5700 UHF MOTOTRBO repeaters (403-470 MHz, 50 watts) with duplexers. These repeaters provide both campus and wide-area coverage and are installed on a water tower located...

Install that was on my 2003 Impala. Uniden 980SSB Leixen VV-898 Uniden BCT7 a.

So this radio has been in service for quite some time and I only recently noticed issues with it. If I am on 2M and it is set as Main I do not see anything being received what-so-ever. If the Main Channel is set to a UHF/70cm channel it does not matter from what I can tell, the VHF side which...

Finally found a Saber Astro in an S split for my GMRS needs. It was in surprisingly good condition aside from the engraving on the front. Programming was done with a Windows XP virtual environment and a maxtron USB cable. Its a bit finicky but it can be safely done. Right now i just have...

I have six Motorola Sabers all allegedly in UHF that I got off eBay and all but one don’t even attempt to turn on and the one that does turn on makes a distinct hum sound and when turned up makes a choppy hum sound. It will transmit at times but then will make the long TX Inhibit tone. These are...

I have an old 1500 uhf r1 kicking around. I have heard about doing a hex edit or something with CPS so it can take those frequencies. Any advice would be appreciated. Just for info, I am trying to RX on the 480 area. Mods, I know stuff like this can be a touchy subject, so close it up if you...

Hello everyone, I'm trying to use the Splat! software, which seems to be old but very nice, but I can't get any correct results. The pictures generated by the software are slanted, and I can't get why. The lines in the picture look like "shifted". I'm using the SRTM 3 elevation tiles. I...

I am so confused on this so i'm gonna ask you guys and see if i can get pointed in the right direction. I want something to block out all other signals on the spectrum except what i listen to which is 150-160mhz and 450-460mhz which is VHF and UHF everything else on the spectrum i'd like to...

Hi all: I've recently acquired a few older Icom LMR radios; specifically, an F3 (VHF) and a set of F4 (UHF) radios, that I would like to reprogram into the MURS/FRS/GMRS bands. I have the necessary software (Icom CS-F3) to program them with, as well as the cable(s) and adapters. The problem...

I have a Motorola SLR5700 UHF 50watt and attempting to utilize the auxiliary port in the back in order to interface an outboard controller. I don't understand why when I set a GPIO pin in the CPS 2.0 software the pin I select does not correspond to the pins on the aux. If I were to program via...

Who else uses the KU4AB VHF / UHF loops? SQ-50 6m square loop. SQ-144 2m square loop. SQ-432 432 mHz square loop. In 2010 I bought the KU4AB SQ-50 single loop, SQ-144 stacked loops and SQ-432 stacked loops that I used for VHF / UHF rover operations. I liked how each of the loops worked well...

I need to know how a dipole for VHF and a loop antenna for UHF are connected together in the indoor TV rabbit antennas?

I'm trying to figure out if there's any kind of solution to linking a UHF Mototrbo system with a VHF analog system. Neither system are encrypted, so I'm wondering if theres some kind of repeater or bridge that can link each other to allow interoperability even if its a DVRS system. Unfortunately...

I have 2 mobile radios UHF/VHF. One DMR one analog. I need both on the antenna but only the VHF one is. Is the best way to 2 diamond X50 antennas? I currently use an old TV antenna that has UHF VHF. But I would love some recommendations THANKS! XPR4550 / CDM1550-LS+

I don't know if this question has already been asked or not but please notify me if it has and link me to the original. To simplify: Why does VHF use 5 watts while UHF uses 4? Full Explanation: I want to know; why are VHF radios set at 5 watts while UHF is set at 4? Since UHF has a shorter...

I was reading this excellent article from the NY Times, and couldn't help my curiousity about what handheld radio Mr. John Roca is holding in his hand in this photo...

Hi, I'm very new to programming motorolas. I've programmed Baofengs and Ailunce HD1s before, which I've been able to figure out. But I'm having trouble with this new Motorola XTS 5000R I bought. I'm trying to program a frequency in it in the UHF band (453.x), but it says its invalid on Astro...

I'm updating our EMS agency's codeplug for portable and mobile radios. I'm adding additions for national interoperability, according to the National Interoperability Field Operations Guide. Since we're currently on UHF, I believe I only need the below channels/zones. I'm looking for any advice...
