I personally, like many others, use whatever is easy to connect to the supply I am using, and make a short 6 or 8" jumper out to an Anderson Powerpole connector.
For you PowerPole fans, do you usually crimp? If so, any particular crimper that you've found you like?
-
Welcome. I would start with the Pinned post at the top of this forum regarding repeaters. There are also articles--such as this--throughout the Internet (including YouTube).
-
Thanks for the pictures. However, I am still a little confused. Are you asking a general question about connecting to a power supply or are you asking about help with a specific power supply you own?
The former. Your following descriptions were what I was looking for; thank you.
-
Could you post a picture, or a link?
Happily; the help's appreciated. Three different styles (threaded, banana plug, PowerPoles?)

4.) The radio only draws 3.5 amps while using the radio at full power, with the cooling fan running. The radio came with large gauge power wires. They are not labeled, but they measure about 2mm. They are likely 14 gauge, rated for 15 amps. That's a plus, as you are less likely to have voltage drop over the length of the wire and the fuse will pop long before the wires become a fire risk.
Is 3.5A during Tx?
-
For me power poles when ever I can.
Generally, red 22-16awg wires, blue 16-14and yellow 12-10 awg. I imagine it is going to be 12-10 for most radios which has an eyelet of #10
kidphc, any chance you could be a little more specific? I'm looking at the Anderson PP site and am not sure which one you're referring to that would work with those round threaded output posts. Thanks for the help.
-
Eyelet connectors? (What is the typical OD measurement of the threaded outlet--for red & black--that an eyelet must fit over?"
If plug or jack, what specs? 2.1mm, etc?
-
Have any of you had success in finding one-size-fits-all as far as a vehicle mount whereby you can swap your ham for your GMRS and vice versa?
-
The first critical rule of radio programming is to immediately save a copy of the codeplug to your hard drive or a flash drive after you have read the radio for the first time.
Sounds like MY first critical rule of radio programming should be to know what a codeplug is and where to find it.

I was referring to the the majority of the Nagoya mobiles I've seen being centered for ham frequencies, not gmrs.
Nagoya claims an "optimal frequency range" of 420-470 in their UT-72.
-
Have a cable, a transceiver and v4.21 software CD.
Should I print something out first or just fire up the CD and see where it takes me?
-
i don't remember a mobile one that's really centered where we need it for gmrs (centered closer to 440-450, if i remember right).
Midlands state they're centered at 462.
-
Well, I think I may have solved the mystery: When I solely use the CTCSS/DCS codes within the Midland manual (vs. what I did which was use what was in my BTech V1 manual), it seems to work. At least the CTCSS codes certainly don't always match between the two. I am surprised there is a difference, but, at least, now I know.
-
It appears the gmrs-v1 has the option for scan for ctcss/DC's codes (on pg 40 of the manual here:https://baofengtech.com/usermanual/gmrs-v1-manual.pdf )
After reading manual Pg 40 (more than once), the example it gave was pulling the tone from another transmitter which already had access to a repeater you're interested in using (by scanning that repeater's input frequency). I'm not clear how it would pull a tone from a Midland FRS turned to a preset channel, e.g., Channel 30 462.7000 (which is GMRS 21).
-
Haven't had a chance to compare the book to this chart (to see if any of it differs) but I stumbled across this while looking for something else.

Thanks for posting this; now I'm really confused. On at least one CTCSS code (#29) that I've unsuccessfully tried in the past (getting my GMRS-V1 to talk to my FRS GXT1000P), there are three different tones: 1) My BTech manual (165.5); 2) the chart wayoverthere provided (179.5); and the Kenwood chart below (173.8).
Why are they different across manufacturers?
Well, at least I've got a few more things to try in getting those two handhelds to communicate in "privacy" mode.
-
Saw the Lscott writeup already; lots of good data. Thanks for the hand.
-
I'm looking at the Tram 1181 (140-170; 430-470) in a NMO fender mount for a dual band application. My assumption is less than optimal (vs. roof mount, etc.) but do you think it'll play within acceptable SWR range?
-
You might wish to look around and see what other antennas people have liked and then pick something that meets your radio and financial needs. But, keep in mind there is no particular advantage to using a Midland antenna with a Midland radio.
Good advice; thanks.
I do not currently own a SWR meter, so I was hoping to find something "pre-tuned." Given that Midland bundles their 3db ghost antenna (I'm looking at either unity or 3db gain given my hilly terrain) with the MXT400 repeater capable unit, I'd expect they'd claim it's fine at those repeater frequencies. The other ghost-type unit I was looking at was the Laird Phantom 3db model (#4503 in black). It's rated at 450-470, with their tech sheet saying < 2.0:1 VSWR across the 20 mhz range. (They also say < 1.5:1 across 10mhz, which I'm guessing is 455-465?)
-
Why are they labeled as such when repeater channel Tx are done at 467? Is it really just a 450-470 antenna, but they brand it as "specific 462" to make sure it's seen strictly as a GMRS antenna?
-
Part # for Otto NC-1 S/M (non-waterproof) is reportedly E2-RE2KA5111 (Kenwood 2.5/3.5mm style).
-
Looking at the Otto speaker mics for my BTech handheld GMRS-V1. Their website showed a lot of options, and I didn't see a way to filter by manufacturer.
Anyone have an Otto that they have for their GMRS-V1 and like?
-
I'd like to have a mobile unit (in addition to my BTech GMRS-V1) in time for hunting season. Processing these choices (are there more?):
1. Get BTech GMRS-50X1 now;
2. Wait for Midland's new mobile unit; or
3. Step up to pricier options.
-
Those extra channels on the Midland are bit of bs. They basically are the regular channels set with tones.
https://www.buytwowayradios.com/blog/2008/05/how_midlands_extra_channels_work.html
Make sure the btech is set the same. Plus past channel 30 on the BTech settings won't be saved.
Thanks for posting this; I saw it yesterday. Per "Danny's" advice, I tried and stay below "extra channel" 38--still couldn't always make it work the majority of the time.
-
Thanks to all those trying to help me.
Short story was that I was able to get my BTech GMRS-V1 to speak to my Midland GXT1000P on one of the "present channels" (e.g., privacy codes); it was between Midland channel 31 and GMRS channel 2 using DCS 1 (D023N).
I tried on three other setups (per Midland's instructions) with no success, although, on at least two attempts, the Midland would light up and show "RX" but without sound when transmitting from the BTech.
Apologies for the poor photography.
How do you like to connect your radio to your DC power supply?

One hopefully last PowerPole question: I have the Wouxon 30A DC power supply on order. (I bought it due to the price point and the fact I'm not entirely sure how high on amps I'll need in the future; currently for a TK-880 which is rated around 10-12A on Tx.) Given that Wouxon unit, is the smart thing to buy the 30A PowerPoles so I know my configuration (Wouxon + wiring) is good up to 30A?
