Flameout

There's a guy in my area that was testing DMR on a GMRS frequency. He supposedly had an experimental license from the FCC. This was a month or so ago and I haven't heard much more about it, so maybe it fizzled out

A good thing about a repeater IDing is that at least you know there is a repeater on that frequency. Let's say you were thinking about putting up a repeater, so you monitor a certain frequency and never hear anyone or any ID, so you think great, the frequency is open! Then you set up your repeater only to learn you're now fighting with someone that already had a repeater set up! I don't know if it is or isn't required, but it's certainly a good idea to have it ID occasionally

I wasn't able to get the r1225 software to run under Windows 7 but runs fine on my Windows XP machine. Of course I may be wrong about Windows 7

Yes, I was telling him that not all repeaters are listed on mygmrs site. I kind of got carried away with the other stuff. Just so he knows that there are many more repeaters than my gmrs shows

OK, good to know. I was just going by what others have posted. The LMR400 is certainly a lot cheaper than hardline

Unfortunately, I don't think very many of the repeaters are listed here on mygmrs. Maybe I'm wrong but I know of a lot more repeaters in my area than the couple listed here. I actually just listed mine last week, hoping to get more people active. I did have 22 requests for access, with 18 of them being within 15 miles and the users went from about 2 to well, 2. Lots of people want access, but no one ever uses the repeaters here in my area I guess you could go through the radio settiings and manually check each pl on the frequency, and if you get lucky, give out your callsign and maybe the repeater owner will get back to you

Not sure, but I dont think LMR400 is especially good for repeater use. Maybe looking into so something like Andrew Heliax LDF4-50a

ok, so I think it's the radio and not the meter , so that kind of sucks. I guess I can go into the settings and lower the output power? I checked it on a couple other radios and the output power was right where it should be. These 2 photos are my Motorola GR500 repeater, on low power and high power, out of the built-in flat pack duplexer

I was thinking that too. I'd love to find a good used Bird at a decent price. When I first bought the FR4000 is was right in that range you mentioned so hopefully it is the meter and not my repeater. If it's the repeater, then it probably isn't long for this world

Oh, I wasn't concerned with power loss from the duplexer, I was just wondering how a radio rated at 50 watt output is putting out 60+ watts

Here is before the duplexer. I'll test the meter on a different radio tomorrow to see if it's actually the meter going bad. The repeater itself is working good though. A Motorola T1504 duplexer and 1/2" hardline to the Commscope DB404 antenna

I'm not sure if I have a bad power meter, my repeater is going bad or what is going on but my FR4000 is initially showing around 60 watts out of the duplexer when first receiving a signal and drops to mid 40's within a few seconds as the conversation continues. It doesn't happen all of the time, sometimes it will be at a normal 41 watts or so after the duplexer. I only have the one meter for now, so can't check using another. I was just wondering if this could be a sign that the repeater is on its last leg and about to die. Oh, the output power of the FR4000 is rated at 50 watts (high pwr)

If you have 3 of them now, can't you take the parts from the bad ones to make one good one?

I had that happen once on a cheap Chinese Fumei duplexer. Not sure what or why it happened. I just ended up buying a used 633-6A-2N on ebay and it's been fine ever since

Not to be a pain, but have you had a chance to look at your settings or your xxx.icf file? I think we must have the last 2 of these radios in existence. Even Icom wasn't able to help me. There has to be a working xxx.icf file out there somewhere, but it is very elusive

Thanks for the replies. I tested the power output with a Bird wattmeter. The repeater for now isn't in use, until I can figure out the CWID problem. Seems that some of these FR4000's will tx a cwid and some don't. I'm not real concerned with increasing the output power. I was just more curious if it was really that easy or if it would harm the radio. I'm still playing around with it. My antenna (DB404) for now is as high as I can possibly get it (about 40'), without getting a tower (and a divorce) and it's being fed with Andrew Heliax ldf4-50a

The output power of my FR4000 is a little below specs of 10w/50w, at about 7.5 watts and 40 watts. Using the process in the attached photo, is it as simple as just increasing the numbers or is there much more to it? Would I do more harm than good by changing those settings? The other two photos are what it's currently set at. No idea if that is factory settings or someone else changed them over the years

I am using both a DB404 and a Comet CA 712 EFC. Both seem to be working well with a slight edge going to the Comet. Weird, but it seems to perform better, but it most cecertainly will not outlast the DB404. Maybe it's the 9 dBi gain over the 404's 5.9 that gives it better performance? Either way, both decent antennas

I'm not 100% sure when it says 50w at 100% duty cycle, but according to this, it is capable of it. Mine is only putting out about 40 watts before duplexer and about 26 watts after. I'm using the Icom duplexer that it came with. Not sure who makes it or if it's even a good one

Sorry I don't know the answer, but I have the same repeater, same antenna and same 1/2" hardline and was thinking about an amplifier and had the same question. Hopefully someone knows the answer. The one amp I was looking at (on ebay) was also 10w in. By the way, does your FR4000 transmit your CWID on a scheduled time? I tried everything and now I'm not sure they are even capable of that

I gave that a shot, but still not working. I either have a partially bad FR4000 repeater, the id-o-matic is bad or I'm missing some setting somewhere. Most likely it's me missing something. Either way, it's frustrating. I always considered myself somewhat tech savvy, but this has me stumped. The IC-FR4000 says it is capable of CWID, but some say it doesn't and others say it does

Would using the mic input of the FR4000 work for this. I think it would be pin 1 to pin 7 (mic), pin 2 to 1, 3 to 4, 7 to 6 and not sure of 8 and 11

I did a similar testing with my IC-FR4000, to be sure it was within the specs. No antenna on the RX side and a power meter and antenna on the TX side. A dummy load should be best to test and I have a dummy load, but it is a cheap $50 piece of crap from Amazon and was getting about a 1.70 SWR using it. I was getting a 1.03 SWR on low pwer and 1.11 on high (Comet 712EFC) You definitely got a heck of a deal on that repeater! There were just 2 of the RFS UHF duplexers for sale on QRZ for $100 each but they sold very quickly this is what my test looked like. Power was much lower going through a duplexer 20230608_131304.mp4

I appreciate you checking your radio. Unfortunately, it didn't work. Your RPT Log layout looks a little different than mine, unless it was just the way you copied the image? I added some of my screenshots. I know I have 120.00 (2 minutes) but makes it easier while I'm testing. Sure would be nice to not to have to bother with the ID-O-Matic but I'm starting to think there's a problem with my repeater or the software

Could someone help with where the pins from the ID-O-matic output would go on the accessory connector of the IC-FR4000? From what I gathered on the hamgadgets.com site, pins 5,6,9,10 and 12 aren't used, but I may be wrong. I would think pin 1 to 25 and pin 2 to 13, but he others I'm not sure off. I tried every combination I could think of to get the CWID of the FR4000 to work properly, but nothing is working so thought I'd try adding an ID-O-Matic board
