  1. Per DX Engineering & RemTronix, the DJ-500TB has been discontinued by Alinco BUT, according to RemTronix, they persuaded Alinco to do another run of the 500TB, & they hope to have them in early December I was lucky enough to grab one from DX Engineering late last month I would keep checking DX Engineering, HRO, & Remtronix for the 500TB
  2. Uh, no Bad catch on my part, I didn't look at the modes being used LAPD is P25, oops, My bad is a severe understatement [hanging my head in shame] At least LASO & LACoF are a mix of narrow band & wide band FM Send me to my room to reread Frequencies & Modes 101 again
  3. I have a BTech GMRS V-1 in the car for my lunch time at work I have the local GMRS repeaters & rail frequencies programmed in And the NOAA weather channels, this is the lousy weather season in Florida My Alincos are my better quality rigs for everyday carry
  4. I haven't actually hooked it up yet, I've been into my h-t's too much, but according to the 778UV software: Band 2: UHF{Rx(400 - 490 MHz) Tx(400 - 490 MHz)} VHF{Rx(136 - 174 MHz) Tx(136 - 174 MHz)}, so yes it will do full capability: 2 meter, MURS, 440, GMRS Bands 1 & 3 must be for Europe &/or Asia because the 2 meter & 70 Cm coverage is reduced compared to the US band plan, so you'd have to use Band 2 here for full 2 meter & 70 CM coverage, even if you're not going to use MURS or GMRS Band 1: UHF{Rx(430 - 440 MHz) Tx(430 - 440 MHz)} VHF{Rx(144 - 148 MHz) Tx(144 - 148 MHz)} Band 3: UHF{Rx(430 - 440 MHz) Tx(430 - 440 MHz)} VHF{Rx(144 - 146 MHz) Tx(144 - 146 MHz)}
  5. I don't use my Baofengs much anymore, I keep them for back up, I prefer my Alinco Part 90 rigs I used CHIRP to edit their coverage down to 151-163 MHz on VHF for the MURS & NOAA weather channels + 462-468 MHz for GMRS
  6. I know that 400-470 MHz is a very common UHF range in the radios nowadays, two of my Alinco h-t's go to 480 MHz [one will supposedly go higher if I update the firmware, but I believe in not fixing what isn't broken], my AnyTone AT-778UV mobile is labeled to go up to 490 MHz, & I remembered that those agencies operate higher than the usual 450-470 MHz, especially LAPD I think that 470-512 MHz is/was called UHF T [for top?] I don't use the GM-30, so I'm not familiar with it other than what users have posted I hope that a software update solves the problem, it is convenient to carry only one radio for multi-use
  7. I just looked at the specs for your GM-30 on Radioddity's web site: Specifications: Default Channels: 30 Channel Capacity: 250 Battery: 1500mAh, 7.4V Output Power: 0.5W / 5W Tones: 50 CTCSS / 104 DCS Tx Frequency Range: 462.5625-467.7125 MHz Rx Frequency Range: 65-108 MHz, 136-174 MHz, 400-470 MHz Your UHF receive is 400 - 470 MHz, it doesn't tune high enough for those departments According to the Radio Reference.com data base for LA County https://www.radioreference.com/apps/db/?ctid=201 LACoF starts at 470 MHz LAPD uses 484, 506 & 507 MHz LASO runs between 482 -485 MHz LAFD isn't even in the ball park, it uses higher 800 MHz channels Have you updated the firmware & software to the current version? Maybe that will give you expanded receive
  8. I never tested the Harbor Freight AA's for their capacity I bought the radio because work was being a PITA about getting me a replacement, since I had to invest my own $$, I wasn't going to go crazy The OEM batteries that came with the Dakota were only 1500-1600 mA, and I wanted some assurance that I could get through a shift without fizzling out The Harbor Freight batteries were reasonably priced to begin with, then I used 20% off coupons to buy them, and they had good reviews on the Harbor Freight page I had good results with them until work finally replaced the h-t, I was using them in my scanner until I bought Eneloops at Costco, they're around here somewhere
  9. I found this page dated May 19th, 2021: https://radioaficion.com/cms/midland-mxt500/ It has specs, pics [probably from the FCC] & a link [definitely from the FCC] to the owners manual Just wanted to share 73
  10. I bought one when work couldn't/wouldn't get me a new h-t I liked that I could use regular or rechargeable AA's in it [2200 mA rechargeables from Harbor Freight worked well for me]
  11. I wonder if it's the Polk County 725 https://mygmrs.com/repeater/335 located in Bartow, southeast of Lakeland It is an open repeater, when the band is open, I have hit it from here in North Clearwater/Dunedin in Pinellas County The ops there said that the antenna is on a tower on the Polk County Public Safety Building You probably had a one-way band opening where you could hear the repeater, but not be able to hit it from your location, I've had that happen to me, having a QSO, & then I drop out on my end, but I can still copy the repeater When the band permits, that repeater can get really good coverage, the first time that I hit it, one of the ops I spoke with said that he was north of Orlando International Airport Hope this info helps 73 Greg WRCZ387 North Clearwater
  12. Yes, the V-1 comes from the factory with preset frequencies, it will only transmit on FRS & GMRS frequencies, but you can enter receive frequencies on VHF & UHF, I think the receive ranges are 136-174 MHz & 400-470 MHz It looks like there are two different models of the GMRS V-1 One model has 22 factory set receive/transmit channels, the other one has 30 receive/transmit channels, so the 22 channel model will not transmit on the 467.5625-467.7125 MHz half-watt frequencies Any channel above either 22 or 30 (depending on the model you have) is going to be receive only, plus, you can't change the frequency on any of the factory set ones I have the 22 channel model I looked at the CHIRP recovery files for both models to reference On the 22 channel model, physical channel 17 is 462.600 REPT 17 On the 30 channel model, physical channel 17 is 462.600 GMRS 17 I'm presuming that there are mixed models of V-1's being used, so on the 22 channel model, 462.600 GMRS 17 is physical channel 9 So, depending on whether your group is talking on the direct channel or through a repeater, all your radios need to say "GMRS 17" or "REPT 17", or whatever channel your group intends to use, all your radios need to match what the display says, then if you're going to use CTCSS codes or not, obviously those all need to match also I hope that I understand the problem correctly, & I hope that this will help get things sorted out 73
  13. Operating practices vary from area to area There are 6+ repeaters here in the Tampa Bay area (3 of which I can reach) Everyone that I've copied or talked to has used their call sign, whether they're mobile, portable, unit 1 to unit 2, etc During band openings I've chatted with users up towards the Panhandle & in Central Florida, & they use their call signs Evidently where you're staying, the users are unaware of the rules or just don't care It's not like that everywhere
  14. My first GMRS antenna was a home-made quarter wave ground plane, my present antenna is a copper j-pole I've had both antennas connected to my scanner & both work well on the civil (118-137 MHz) & military (225-380 MHz) air bands, plus the local rail freqs (160-161 MHz) Considering that both antennas are tuned to 465 MHz, I've been happy with my air band reception I'm going to connect an inexpensive discone to the scanner so I don't have to keep switching back & forth when I want to use GMRS I'm also going to check the GMRS performance of the discone, just to satisfy my curiosity
  15. There are two repeaters in downtown Tampa .575 antenna height is 500' .700 is at 400' I'm in North Clearwater which is about 25 miles away .575 has covered up into Pasco County to the north, & into Polk County to the east, I don't know how far south that it's reached I don't know how far .700 has reached I can hit both repeaters from my location with an h-t, so they both cover more than 10 miles
  16. When the weather permits, you can get band openings on UHF I live in North Clearwater, FL In February & March, I have hit a repeater 57 miles away from me in Bartow/Polk County with my h-t when the band was open One of the ops I spoke with was in Orlando, 10 miles north of the airport, which placed him 75 miles away from Bartow On that night for only a minute before the conditions changed I spoke with an op from Perry, FL, in North Taylor County, that repeater is on the same frequency & tone as Bartow North Clearwater to Perry is 153 miles as the crow flies It can happen I check the NOAA frequencies, when I start hearing out-of-town NOAA broadcasts, that's a good sign that the bands are opening up Edit/addition: WRMC383, I looked your location up just to see where you are Just a few nights ago, a gent in Grand Island which is in your neck of the woods made it into the Tampa .575 repeater, that's about 78 miles from him I spoke with him just before midnight & conversed for about 20 minutes before he said goodnight, I forgot which day it was, but it was earlier this week If Mother Nature is in a good mood, it can be a good thing for us radio ops
  17. The 105 isn't repeater capable, it operates on the simplex channels only The 115, 275, & 400 can go on the repeater channels They are more expensive, but you gain the repeater channels & higher power output
  18. Got the e-mail notification,I just placed my order I've been happy with the 771G so far, getting more so each h-t has one They're now offering BNC & SMA-M connector models also I'm hoping that the NA-701G comes back in soon, I'd like to try one of those I ordered one of the NA-701C (commercial tuning) from myGMRS to test out in the meantime
  19. Are you asking about just Part 95 radios or any radio that can do the group scan? I'm asking before I answer, so I don't open the usual can of worms
  20. The NA-771 is tuned to the amateur frequencies, not GMRS, that's why the SWR was so high 440-450 MHz compared to 462-467 MHz, that's a 20+ MHz difference The stock antennas are usually very broad-banded & inefficient I just looked at mine & it's labeled 136-174/400-520 That's probably the antenna from the UV-82 radios The least expensive quarter-wave for GMRS [that I know of] is a Nagoya NA-701C, which is tuned to the VHF/UHF commercial frequencies [so it would also cover MURS on VHF] and is way closer to GMRS It's sold in the mygmrs.com store for $14.99 https://shop.mygmrs.com/collections/antennas/products/nagoya-na-701c-antenna You spent $7.79 & some time to get an antenna that will perform on the GMRS frequencies I'd say that you broke even
  21. It will be easier to use channel mode instead For example: Say your repeater is on 462.600 Arrow to REPT17 Say the CTCSS on both input & output is 100.0 Press Menu, then up arrow until you see R-CTCS OFF, press menu again, up arrow until you see 100.0HZ, press menu to confirm Up arrow to T-CTCS OFF, press menu again, up arrow until you see 100.0HZ, press menu to confirm You should now be set up to use the repeater The radio will automatically know the receive & transmit frequencies and you have manually entered the CTCS tones If the the repeater uses split different tones for input & output, the steps are the same, just select the tones that you need
  22. Good Afternoon jas, I'm in North Clearwater/Dunedin & I have heard the signal on .700 also It's often enough that I locked out .700 on my scanner, as I usually have the repeater outputs scanning continuously 73 Greg
  23. I have a Nagoya NA-771G half-wave and it has performed well for me so far I have a TYT branded SW-102 meter and I tested the 771G on 5 radios, 2 Baofeng, 1 BTech, & 2 Alincos SWR ran from 1.03 to 1.20 depending on which radio & which end of the band I will order more when they're back in stock I will order a NA-701G quarter-wave when they're available just to see how that one works vs the 771G 73
  24. From the specs, this user has a slightly different model of Tram antenna, but hopefully the tuning method is the same, or at least similar http://pascogmrs.us/tram-1486/ If not, I would do a web search for the instructions for your particular model I hope that this helps 73 Greg
  25. If I'm wrong, I know someone will have the correct info Blue & Green are 154 MHz & use wide-band which some ops say will give you better audio quality The other three are 151 MHz & use narrow-band which some ops say lessens your audio a bit If you do go the MURS route, you're limited to two watts, but you can use an external antenna like replacing the stock antenna on hand-helds, or connecting a base or mobile antenna to them, depending on where you're using the radio GMRS lets you use more power, but MURS may work better for your situation, being VHF not UHF sending your two watts into a better antenna may level the playing field so to speak It's a situation where you may have to try both & see which works out better 73 Greg
