I found my RIM RLC USB FOB.....but I cant remember what the ip address is on the Pi....I dont have a monitor handy (Im at the tower site now),,is there a way to determine it from the ETH connection? Ive been running ZENMAP to try to find it via scans but no joy...If I can figure it out, I can SSH in and set it up and have my allstar node on my new site today (its an hour drive from the house)... Any ideas?? Thanks Chris WB5ITT

I had a question posed to me so thought I would pose it here. The local club has a 7cm DMR repeater antenna is at 500 ft.. They are interested in adding a GMRS repeater use cavities to combine the two to use the same antenna. Has anyone seen that style of arrangement? I know major radio markets you see FMs use combiners, but this arrangement is not involving only transmit. Any thoughts appreciated. -- Mikeal R. Hughes, BA., MA., D.Min., Th.D.

I'm going to be ordering a polyphaser surge protector to put in line with the 2M repeater heliax. Im noticing some have specific frequency ranges. That has me wondering, does that mean they will block signals they are not rated for? Seems like that might be useful for having a little extra filtering.

Any sources for a UHF low pass filter with the following spec's. Must pass 450MHz 449 receiver, reject 494-500 (TV Channel 18). A tower that I am on for free, has allowed a 15KW ERP LP UHF TV station within 20 feet of my antenna. I have some desense that I would like to attempt to filter out.. Thanks

Greetings fellow Repeater Builders, I have attached a RIM-Lite interface to Port-3 on an Arcom RC210 repeater controller. The RIM then attaches to a Raspberry-Pi running Asterisk so it can access the AllStar network of Repeaters. Repeater-Builders supplied sample configs for both Asterisk as well as for the RC210. The problem I am seeing is that audio coming in from a local RF user of the repeater is being repeated out on the transmitter as it should be, BUT the audio sent out to AllStar is *also* being echoed back to the repeater to go out on the transmitter causing a terrible ECHO. I have used the settings prescribed in the sample files from "Repeater Builders" for RPT.CONF and SIMPLEUSB.CONF, and the settings recommended for the RC210. Perhaps there is a setting that needs to be modified to prevent audio that is being returned on AllStar from being mixed/repeated whenever a local RF user presents COS??? This works perfectly if you are the ONLY user on the repeater (so I didn't notice it immediately), but if there are two or more users we notice the echo. Is anyone else here on the list using the RIM-Lite on an RC210, have you experienced this ECHO, and how did you go about fixing it???

I have had my DR-2x running through a HRI-200 for over a year not. Suddenly there is no connection from the Wiresx software to the transceiver. When I view the transceiver in the File dropdown, the window pops up. All of the settings are there, but everything is greyed out. I cannot change and apply changes. Any ideas on how to get the software to recognize the transceiver again? I have rebooted the repeater, laptop, and HRI-200. Usb to HRI-200 is working, I have also tried unplugging and replacing the data cable from the HRI-200 to the ACC port on the repeater. Any ideas appreciated. bill

Hello RB members, I have a potential project that I thought I would list for those of you who like things like this. I have the bottom half of a Decibel DB-420 16-bay antenna array here that is cut for the 470-490MHz band according to the dipole loop sizes. They are a good 1.5-2" shorter than the 450-470MHz cut versions I have used in the past. The harness is in great shape and there is no damage to the hardware. Basically it is laid out like a DB-408 with the connector at the top of the harness to feed another DB-408 making up the full DB-420 16-bay array. I will ship it less the bottom half of the mast to anyone needing it or interested in a project for $150 + actual shipping to you. Maybe it can work on GMRS frequencies since they are quite broad banded, maybe the harness can be terminated at the mid-point connector and used as is, maybe someone can modify the harness and use it as is. Basically it is a project or for someone with a damaged bottom half of your DB-420 higher cut that needs the parts. I don't see many parts for these come up anywhere so I figured list for the RB group. Thanks for looking, Rick w6re

Hi George, Here in Australia we have a "Men's Shed" movement supported by our government as a "Men's Health Initiative". This gives an opportunity for antennas on the building. And, with sufficient members interested in radio, a community. Then there's HF repeaters! Our Ambulance service has invested in HF digital radios in 100+ vehicles and stations and thus a mesh network. All we hams need is to convince the software developer of such as FreeDV to think along the lines of, data in the transmission such that an intelligent receiver can decide to repeat (do something) a signal or not. We have CTCSS tones in VHF/UHF repeaters and here we use just three of the 50+ tones, so three bits/sec would be enough.

Towers were my responsibility. I can tell you that as much as I wanted to get hams on our towers my hands were tied by two of the worst parts of the biz world, insurance companies and lawyers. The couple of times we were able to accommodate hams was where the capacity for antennas were included in tower design. And I'd give the group a zero dollar lease that I could terminate with 30 day notice if I had a paying customer. Heck, even for my own repeater back in the 80's in Austin the only way I was able to get on our tower (I was chief engineer at this station at the time) was when a paging company abandoned their antenna/line on our tower. During a lamp changing session I had the guy doing the work to swap their antenna for my Stationmaster. But more and more as insurance was dictating and our own lawyers looking over our shoulder the deal was this: anything going on the tower needed a structural analysis. If changes were needed to accommodate the antenna the "customer" was responsible for paying for the mods. Climbers needed big insurance and the tenant needed insurance. That's just the way things went. > > And if you look at the tower and figure the antenna and line won't hurt you can be very wrong. > > What didn't help me was my experience in 1996 when I was in DFW and having work done on one of our 1500' towers in Cedar Hill that a tower crew made an error hoisting their "gin pole" and with three guys on the tower collapsed the tower, three dead. I had engineering done on it but the crew made a mistake and the tower came down. THAT one error cost a huge amount of money, insurance didn't quite cover all since our tenants sued us, the deceased's families sued us. And we sued the tower company. Who won? The lawyers. I met many lawyers I could have lived better not knowing (except ours-he was a shark). Met OSHA people. It was ugly. And then we needed to build a new tower. Not cheap > > Add into this the fact that it was a "thing" back 15 years ago for stations to sell their towers to companied like American Tower, then lease it back (never made any sense to me) so many towers that were locally controlled were now corporately managed. More damned lawyers. Companied like this now control towers, rooftops, water tanks, etc. I've been wanting a site for one of my 900 mhz repeaters here in Ft. Worth area. Just not happening. My other one is on a tower that had an abandoned paging antenna and not managed by the corporate world. > > GeorgeC W2DB > > --------------------------------------------------- Alan VK2ZIW Before the Big Bang, God, Sela.

I've been debating on trying to aquire a site to put a repeater vs here on my vertically challenged tower. In the past I've found contact information & asked tower owners for space. But this was probably 18yrs or more ago. One spot almost worked out, but in the end engineers said the tower was already too loaded. So that was a no go. Then at one other site I was actually offered space, but I decided not too. Just because of location wasn't desirable to me. Then I've also heard horror stories of tower owners changing hands & Hams getting locked out & stuff turned off. ? Now here recently I decided to kick the idea around about acquiring a site again. In particular one of the sites I was almost in the door on years back but engineers said it was too loaded. I've noticed the tower has had most everything removed now. So I wonder if that might be a possibility. What I am curious about is what all is to be expected. So I figured I'd ask here..since there might be a high probability of Hams with repeaters on towers owned by others or government organizations. Do you have to carry insurance with having space on them? Was is difficult to get the equipment on the tower with red tape? Do you have free access to go there whenever needed with keys? Do you pay anything for the space? Do you pay anything for electricity? What do you feel helped you aquire the space? Little background about myself. I started off rock climbing in my youth. I was already into radio. Later that led to working for a tower company doing installation & tear downs of towers/equipment. This also helped fellow Hams around me. I'd donate used long runs of heliax to local clubs. Plus help put up repeaters & equipment on commercial towers for other repeater owners. Im older now & I don't do tower stuff for others anymore. Having kids & wanting to be around for them changed a few things for me. Im still willing to do tower stuff for my own projects though, just because of necessity. I have land here. I've always wanted to just put up 120ft or more of tower of my own. Life always seems to say nope. You can't afford that now. Its a shame though. I actually live on a good size hill with nice HAAT. Radio communications do really well here. Its just having a repeater with antenna at tree levels still produces shadow areas plus foliage antennuations when leaves & greenery come back in season. Ideally having one here would be less worry I feel. If you don't want to reply publicly here you're welcome to email me. N4fox.r@...

An organization I work with has an old Motorola GR1225 (business freq) with an odd issue that we're trying to diagnose. None of us are radio technicians...just audio/visual & IT guys (a couple of us with basic ham radio background). After some transmissions (seemingly at random...maybe 2-3 times per hour), the repeater hangs open and transmits loud static for around 30-60 seconds. In the last 10 (or so) seconds, the static begins getting quieter and cuts in and out until the repeater finally drops. We were able to get our hands on the software and will be attempting to connect to the repeater for troubleshooting tomorrow.... in the meantime, does anyone recognize this behavior? What should we be looking at to fix this? Thank you!

Does anyone know anything about the Crescend Technologies P25-2AC1-C1-002 amplifier? I found one that is for sale and its label says it operates 42 to 50Mhz and 2.5 watts input for 250 watts out. But I'm trying to figure out if it will for sure work okay on 6 meters, or if it can easily be modified to work there. I need it to operate on 53.19Mhz. Has anyone successfully used one of these amps on 6 meters? I have looked on the internet and have found no information on this amp. Even contacted Crescend directly and they told me they no longer have any documentation on it. Thanks, Dan

Hello to all. I have a real nice Kenwood TKR-850 repeater that I have no location for. It is currently on 444.700. I will program it for you and ship it for 575.00.

I'm trying to get rx audio from the mic jack on my CDM1250. The pinout says it is the same as the maxtrac and I should have rx audio on pin 8, however it isn't there. I'm using a signalink USB and trying to setup echolink on the CDM rather then the maxtrac. Everything works fine on the maxtrac, but if I plug it into the the CDM there is no audio. I was going to use the accessory connector (pin 11) but that is unsquelched. Not like on the maxtrac where you changed the jumper on the inside for PL to unmute the audio. Not seeing anything in the RSS to set pin 11 for muted or PL audio. Thanks for any help.

i am looking for a dtmf decoder to connect to a receiver to decode our local ema whelen siren to give a message on the repeater that the sirens have been activated i monitor the frequency that they activate the sirens on and the dtmf is very fast i am sure different tone sequence has different meanings i just want an announcement that the sirens were set off ,any thoughts ? Thanks

I’m looking for the connector to go on the back or the whole cable kit for a dc backup on a quantar. Does anyone here have anything they would be willing to part with? I can’t find anything online. Thanks!

I have a good condition works fine Kenwood TKR 850 Peter with about 30 W output and the receive sensitivity is about .25 mill volts. It will come with a power cord with Anderson power poles on one end. This Peter was just tested by a local radio shop and was determined to be working with good performance. $600 plusshipping.

Does anyone know where to get the service manual for the DR-2X? I have tried OEM's site, manuals dk, etc but nothing yet. -- - Regards, Karl Shoemaker Please remember not to reply (email) from this group as I won't get it.

hi , does anyone have any of the following ? a cable from a Kenwood T K R eight fifty to the S com seven three three zero controller ? and , I'm looking for a copy of the programming software for that controller . weird question , is there any blind hams on this list who may have used the programming software with a screen reader? And is that accessible? A screen reader is a piece of software that reads text on the screen out loud so someone who can't see the screen can hear it and interact with programs and a computer.
