    Midland Syn-Tech III P25 Radio Model: STP-404A

    Have been doing some research on the radio and coming up blank as far as user comments or feedback is concerned. Anybody use them and if so what are your thoughts, and how does it compare to some of the other P25 portables on the market. I really like the channels, user functions and other...

    Cos sanders used for mono and repeater???

    So I’m sitting around at work. It’s a slow day. I’m just bouncing around on YouTube, radio reference forums, google, etc... and a wild hair sparked a theory. Therefore I have to ask the experts! Would it be possible or feasible to use two cross band rigs in conjunction with each other to achieve...

    If this thread better belongs somewhere better, moderators feel free- I'm listening to a local business on one my of my Motorola P25 handhelds but I've cross tested this frequency on a few of my other radios that include Kenwood and the same thing happens where, ever so often, an interference...

So, I have had my SDR connected to my only outside UHF antenna (usually used for my only UHF base radio for SARNet etc...) but i hooked the sdr up to confirm and receive DMR...

    700/800/900 MHz......Why?

    Most large scale radio systems, especially trunked ones, seem use the UHF High Band frequencies to broadcast signals. That doesn't make sense to me. Wave propagation of 700/800/900 is very linear and tends to avoid wrapping around terrain like VHF Low (and to a lesser extent VHF High) can, which...

    CHP UHF Frequencies

    Hello RR! Looking at the CHP database here, I noticed that under the Division Wide sections there are some UHF frequencies, usually just named "UHF 1" and "UHF 2". Does anyone know what those are used for? As far as I'm aware, CHP is usually on lowband. Any insight into this would be greatly...

    HT-1250LS question

    Good day all, A few days ago I purchased an HT-1250LS UHF handheld, was excited to get it, hooked it up to CPS & much to my dismay discovered that it doesn't do MDC-1200 (which I rely on heavily for Radio ID's and repeater functions & such...), it will do MDC-1200 in LTR Trunking mode but not...

    US DoD (14C) Key West NAS Site

    Spending a few days down South, way down South! And brought my Whistler TRX-1 along for some entertainment while walking the dogs. The county P25 system is coming in great, even heard the NAS tower, but the trunked system has been quiet for two days. The last 12 hours or so I've been...

    Standard C790L Information

    I was given a Standard C790L radio. I don't know much about it and there hasn't been much turned up on my Google searches. Hopefully someone on here can help fill in some of the holes in my understanding. First off, I know it is a commercial UHF radio. I read one ham's website that a simple...

    Picking the right dummy load

    Hello there, My question is not amateur radio specific but I couldn't find an exact sub forum for my question. I hope it fits in here anyway. (Suggestions?) English is not my primary language, sorry about any English "drifting" of my part. I'm very new to the RF world so (one of) my first task...

    All This for $25!

    I'm new here, and new to SDR, and I'm having the time of my life. Way back in the late 1960s, the USAF had me sitting at a console, staring at VHF and UHF frequencies on a spectrum display, for reasons I can't really discuss still. My guess is that console cost half a million dollars or so...

    Lincoln County DMR??

    Is there anyone else here in Lincoln County, specifically Lincolnton? Lincolnton PD is on UHF 460.450 MHz and normally there isn't any issues, however for the past few days there has been some major interference on their channel. At first I thought it was just bleed-over from another agency...

    French Exhibition Team

    They flew here in Sacramento yesterday and left for Canada last night. They have 10 Alpha jets and 1 humungous A400M. Of the 10 frequencies I gleaned from the Internet I copied them on two, 340.300 and 141.825. It would have more fun if I understood French, of course. Yet the A400 was all...
