Is there any special charger version that works best for the UV-3D if it’s has the Lithium ion battery pack with it..? Does the UV-1P charger work fine for the higher version radios..?

I bought this primarily for scanning. The firmware is the older version that works well with scanning. The mic and mounting bracket are still in their packaging. Screen has a few minor scratches as seen in the pics, but aren't really noticeable when the radio is one. Also included is the...

I know I can't be alone in wondering if Hytera will ever produce a dual band radio. I would especially love to see a version of the PD782 or PD982 that has both UHF and VHF capability. And certainly I'd like to see a mobile rig from them that does the same. I understand why they haven't gotten...

Looking at installing a ground plane antenna on a mast for VHF UHF and have a couple questions. I see the 5/8 wave antennas have a tapped coil for matching (to 50 ohm?), are clamped to the mast, and have horizontal radials on the coax shield side. Are the radials supposed to supply the entire...

good day, I am currently working as a CPO in Alberta, the department im working with is brand new and we are essentially replacing a security company that operates on UHF to talk to their officers and other staff within the organization. This is the challenge I am facing, some staff cannot...

I'm about to pull the trigger on a ID5100a. I have an 880h now and looking for some more options when scanning/transmitting. I have a 3/4 ton truck with about 9" of clearance to the top of the header board going into the garage. A friend of mine recommended some Stico antennas citing they were...

I have a vertex vx-929 radio with a dual band chip installed, what part of the board might I find the chip installed if I take the radio apart? Is the chip easy to remove and swappable with another vertex radio such as the vertex vx-824 P25 radio?

I bought a Diamond RHC77CA antenna listed as 120-900mhz for my Whistler WS1080. I bought a cheap import on eBay that was shown to be the same size and multiband range. What was sent from eBay was a Similar looking 16" whip, Nagoya NA-771 dual band 144/430mhz antenna. As a newb, will this...

Hey all- I'm currently running a dual-band TK-790/890 radio in my vehicle. I upgraded to this after using a single-band, remote-head 790 for over a year. To upgrade to both bands, I got the entire (dual-band, single head) setup used, and had my local Kenwood shop upgrade the firmware in both...

After quite a bit of searching online I'm stumped and request some assistance from the forum. I'd like to set up a base station for lack of a better term at my home and listen to as many frequencies as possible with the most interesting ones for me being at approximately 155mhz, 455mhz and...

Okay, so I am new at this to a degree and I have a question that I think I might know the answer to, but wasn't sure. Basically, my company uses both VHF and UHF commercial for on location communications. One group uses the VHF band while the other uses UHF band. I, however, now have a dual...

Have been doing a lot of reading on the Antenna Forum and have concluded that getting a Larsen NMO150/450/800 fixed mount antenna makes sense for the type of monitoring I am doing. My only concern is VHF-Lo band for Maryland State Police. Any suggestions on a low band mobile antenna to mount...

I'm looking for some suggestions for a new dual band antenna. What I was using was a Comet CA2X4SR that recently began performing very poorly after a tree branch strike. Well, I pulled the antenna and tested it and it has an internal short somewhere. Lo and behold, also damn near pulled the...

I have two working Vertex VX-5500 units (one a VHF C deck, the other a UHF D deck) that I am trying to reconfigure into a single control head, dual band set-up. I can not seem to get the programing software to recognize them in order to program them as a dual RF deck configuration. I have...

I have a TK-5710H VHF radio with a KRK-14 basic control head. I just recently purchased a KRK-7DB dual band connection setup and a TK-5810H deck to make my system a dual band system. I have installed the KRK-7DB, the TK-5810 deck and connected all to the currently installed TK-5710 and KRK-14...
