Where’s the emoji for envy when I need it?

Seriously I have to quit buying radios. I have two of this model already. This last one gives me three. I also have three of the UHF models too. The only Ham digital mode I don’t have a radio for yet is System Fusion. I might not be able to resist and get one sooner or later.

? I’m not falling for that ? p.s. congrats

I just won an auction for another radio tonight. It’s a TK-5220 which does FM and P25 Phase 1. I think I have enough radios. Now I have to find time to play with them.

I only use 11 codes and 13 codes....even numbers give me bad dreams. I am 11-47 - Means I have tacos I am 13-49 - Means I need tacos

Pardon? "once the FCC permitted repeaters..." Repeaters have always been a part of GMRS (and precursor Class A Citizens Radio Service [Citizens Band used to be Class D Citizens Radio Service). And users only had access to TWO of the "main channels". The 7 intersitial channels are lower power (5W... HT level) simplex channels positioned between the main channels (there is just enough gap between channel (25kHz) and bandwidth (20kHz authorized, 16kHz deviation standard)) that the filters in the radios can "tune out" any actual overlapping traffic (cf: FM capture effect). Many of the old repeaters were provided by companies (when GMRS allowed business licenses) and used controllers that could handle multiple CTCSS assignments -- so the company could configure different tones to different groups of users, including providing a tone just for (paid/approved) private users (GMRS equipment wasn't that common, and with only two main channels on the license one couldn't randomly search for repeaters). Granted -- protocol pretty much mandated that one use MONitor before touching the PTT to ensure that a different (higher priority group -- like the business itself) wasn't active on the channel.

Just got a new Retevis RT97 up and running in East Anchorage. Location is near Boniface and Reflection Dr. Using 3 element Yagi pointed south from my Condo balcony. Transmissions to the west are mostly blocked. Hopefully, this will work most of East Anchorage and possibly toward Eagle River if mobile or base is used. Best reception should be good on the Hill Side. Will need testing to see what the actual coverage is? The initial tone setting is 141.3 for input/output. At some point I plan to change to a DCS Tone. Please be mindful of other users of the frequency. All GMRS frequencies are used on a shared basis. No one owns any particular frequency. So, before you transmit to access the repeater determine the frequency is not already in use. If you use Tone Squelch you may not hear other uses of the frequency. In order to determine if the frequency is clear you will need to open your squelch in some way. Use your Monitor feature if your radio has it or use another channel on your radio that has carrier squelch. If possible, just set your repeater channel to use carrier squelch instead of tone squelch. Also, remember you are required by FCC regulations to use your FCC issued GMRS call sign when you are finished with a conversation. There's no need to repeat your call sign after every transmission. If you are in a long conversation, you must repeat your call sign every 15 minutes. However, let's not tie up a repeater for that length of time. Others may be waiting to use the repeater. Try using a simplex channel, if you are close enough to the other station, to continue a conversation. If you have an urgent need or emergency you may break into a conversation by saying "break, break, break". Others on the channel should yield to you. If you would like to join a conversation just you drop you call sign during a break in the ongoing conversation. Let's keep all conversations family friendly. And above all be courteous. One last thing. If you are running a business don't use this repeater (to run your business). There are licensed frequencies available specifically for businesses. You can obtain a frequency that is not shared by others. There are other license free frequencies available on a shared basis in the MURS or Multi-Use Radio Service. These fall under Part 95 rules but are not likely to be used by the general public. If you are not familiar with the rules governing the GMRS please refer to FCC Part 95 subpart A. CFR-2009-title47-vol5-part95.pdf (govinfo.gov)

Sorry that you have been triggered. I have more quotes if you need them. How much money do you have?

It's less syllables to just say I have tacos or I need tacos though... and why would you risk such an important thing being misunderstood??

My wording could have been better. My main point was that, when the FCC permits repeaters in a shared service, repeater users cannot always protect simplex users from interference (IX). So when you are planning a repeater, digital or otherwise, while I try and work around a local simplex group that call a certain channel home, eliminating interference is not always possible. Thus, simplex users cannot expect interference-free operation (except intentional IX).

DMR channels do not use 7.6 kHz of spectrum; they each use 12.5 kHz but they use time division multiplexing to share that portion of spectrum. In other words each current GMRS channel would only represent two DMR channels. Gil is correct that this would impact everyone who has an analog GMRS radio. Use of such a radio requires the entire channel, making it unavailable for DMR. Conversely, to those who have analog radios, every DMR transmission sounds like an impact wrench. “Here in California, CERT, neighborhood or fire watch, militia groups, etc. have implemented GMRS because 80-90% of their members have no direct interest in the technical aspects of amateur radio.” I don’t know how true that statistic is, but ruining GMRS for the rest of us isn’t the answer. P.S. People who have no direct interest in the technical aspects of amateur radio might have a tough go when they have to program a codeplug. DMR codeplugs are extremely technical. I guess you could sell the radio with a basic codeplug that’s simplex DMR on 1-22 and duplex on 23-30, but what do you use for talk groups, time slots, and color codes?

Why not just take the test for amateur radio if you want to do as there are plenty of dmr repeaters. I'll stick to my p25 radios. Sent from my SM-S918U using Tapatalk

Welcome in! Ask us anything. If we don't know we'll make something up. Just kidding. There's a substantial knowledge base here.

Generally, we'd want to stick to the "GMRS" frequencies from channel 15 to 22, since all GMRS radios can transmit on those channels regardless of power level. In Eagle River and the Valley, channel 16 probably gets the most use between the repeater here and the Golden Eagle folks in the Valley. Channel 20 gets more activity on weekends, particularly amongst offroaders out on the Moose Range trail system in Palmer.
