Tesla would've put electricity over the air and ruined all possibility of radio lol. Great guy,.. Not a friend of radio though...
-
Stick a penny in that fuse box and you can power a 100 watt radio with a cigarette lighter plug Just keep transmissions brief..
-
Yeah I don't really get why the cigarette lighter plug is a knock on the radio. I guess you're not a cool kid unless you splice up your dash wiring? lol The point is that the amp draw of the radio is such that the plug connection is sufficient.. My truck has a bonus auxiliary DC plug down on the middle console. So,.... yeah.. I just plug it in right there.. And now I can have the option of yanking the radio out and putting it somewhere else should I choose. And if you just really hate it, I'm pretty sure a pair of scissors and 10 seconds of time can solve that for you pretty decisively..

I like the cigarette lighter plug and I use it. It's actually part of what I like about it...

Man,.. If people are impressed by Midland IDK what the hells going on . Before GMRS got popular, Midland made $40 Walmart CB radios.. When did Midland become yaesu?
-
I mean.. It's a loaded question. I don't own "all of the radios" so I can't say for sure. Rubicon probably does lol. But what is "better" anyway? Specs? We're not supposed to be a nerd band theoretically. But I know that a lot of us are. So maybe you care about if the receiver is a superhet receiver. BUT, how does that weigh against the functional advantages of the radio I'm reviewing in this post? Size, the user interface, power draw, etc.. Maybe I can make the argument that this radio is "better" because those are the factors that matter to me for my use case..

I've been operating with a Radioddity DB20G in my truck since Christmas. I wasn't planning to make a fuss over it or type up a review or anything, because I felt like it was a pretty basic, standard, inexpensive, knock around mini-mobile GMRS radio. But after using it for these weeks, I've noticed that I just really like this radio a lot. It does all of the small things right. It may sound silly to some, but I just really appreciate that it uses a big switch on/off volume knob. For a radio that I operate in a vehicle, I appreciate it when a radio isn't "fiddly". I reach over blind, switch it on and set to a comfortable volume in one intuitive and effortless motion. The radio sits in a spot that is absolutely perfect in my truck (pictured in following post). Facing face-up below where my right arm would rest on the middle console. The speaker is powerful and can be cranked up adequately loud to hear comfortably above road noise. I also appreciate that this radio is 20 watts (and actually is) which means that it can safely be powered by a cigarette lighter plug. When you power on/unlock the radio, you have full freedom to program as many simplex and repeater channels as you'd like. I used the included bracket and some 3M hook and loop strips to make it so that I can simply pull the entire radio off to bring it inside for programming, or use it in another application. Reception is great, no breakthrough overload, and reports are that I sound nice talking on it as well. It just hits the sweet spot of preferences for me in a radio for how I want to be able to use a radio..

Varying power levels depending on antennas...
SvenMarbles replied to SvenMarbles's question in Technical Discussion
No, it's the common inexpensive Surecom 102. But, I do look at it with a Nano VNA when I put up new antennas. There's never that much of a discrepancy.. But assuming there was perhaps a .1 deviation in reflection, would that account for a 20% difference in output level? Because that's the sort of thing that I encounter.. -
Well I'll admit, this is something that kind of puzzles me and I'd like to understand why this happens. I've experienced many instances where your radio's output power seems to be influenced by different antennas on the other end. For example,.. You have a mobile/base radio, coax, in-line power meter, coax, antenna. It's a 1.1 SWR and it reads 40 watts output. You then don't change anything except for the antenna and the end of the line, but now you're getting a 1.1 SWR and 32 watts on your power meter. How does the power level between the radio and the power meter get influenced by the antenna at the end of the equation? No additional reflection shown on the meter... Does anyone else notice this happen?

Something very strange is happening
SvenMarbles replied to SvenMarbles's topic in General Discussion
Is that the case? You can operate a constant broadcast on FRS? -

SvenMarbles replied to SvenMarbles's topic in General Discussion
Just don't even worry about it. It's not really the issue I'm bringing forth in this post. The point is that there's an interfering signal parked right onto a GMRS channel. -

It's exactly what I wish I had. I can't really swing that purchase. I'd love to just borrow one for a day! Or task someone who might own one local to me with the challenge.. -

That’s got to be what it is… Thanks! So if I key up on the correct DCS tone, maybe I can come through the intercom and make noises that might convince them to disconnect it -

Truthfully it was cold out and my hand was getting frozen holding up the Yagi on a stick thing I have lol. I did like 5 points and gave up. I use a little 4 element LMR band yagi and a Alinco DJ-X11 handheld. All mode wideband receiver with an S meter and attenuator levels… -

I spent a little bit of time shooting azimuths with a yagi and have a general idea the region that it’s in, but I was never able to get on all sides of it to converge everything. -

I’m aware… I’ve got over 300 people in my city with radios programmed for this channel. Most of them not at all familiar with how to do much with the radio beside switch them on and key to talk. We’re set up to use channel 22 and to pivot from that would be a hair pulling mess. I’m not sure what point you’re trying to make anyway… This thing isn’t supposed to be operating in the way that it is. -

This has been transmitting for weeks. -

I noticed weeks ago that there was some sort of constantly transmitting signal interfering on GMRS channel 22 (462.725). I spent the better part of a couple of days driving around direction finding. I can hear this signal for MILES. Tonight I noticed it again, but this time I can actually hear FM audio and it sounds like ambient sounds inside of a person's home. A childrens cartoon is clearly audible and occasional sounds of kids. When you switch to USB, you can hear some sort of data. Ok so baby monitor? But,... for miles? And why is it on 462.725mhz? Is someone doing some shady surveillance on someone and I've come across their listening device? What do you guys make of this...

I'll vouch for the Retevis 40 watter. The RA87. I use that at home on the Comet GP9NC. Beast..
-
I'd have a look at the Comet CA-GMRS Comet is a reputable brand, not terribly expensive, and not super high gain.
-
Info for that antenna shows it being a little bit out of spec for GMRS. 450-460.

help needed in adding a GMRS repeater on a Tidradio H8 Gen 2
SvenMarbles replied to WSGF380's question in Technical Discussion
My mistake.. Menu 11 for CTCSS output.
