[Repeater-Builder] Kenwood RBI-1 Radios For Sale - TM-241 and TM-441
Hi All, Hope you don't mind this For Sale message. I had a Remote interface using a DHE RBI-1 connected to our Link-Comm RLC-3 controller. We decided not to continue with the install and pulled it from operation. Never actually opened it to the users. I have recently parted with the RBI-1 interface and now have the 2x radios, Kenwood TM-241(VHF) and TM-441(UHF) that were being used, now surplus to needs. These radios have had little use and are still in very good condition. I have checked these recently and are still working fine, power is still 5,10 and 50/45 watts. Condition is in good condition, I can supply photos to those of you interested. These radio have had a couple of mods done to them. 1. They have been frequency expanded 2. I removed the SO-239 sockets and replaced them with bulkhead BNC connectors. These gave us a fix connector for extra support. They will be sent in the orignal boxes with manual and non-DTMF mics (came with them). The only missing item is the power cable. I had these connected in the repeater system and they are missing. I have included the power connector to teh radio, will only need the fuses put in line. Any further questions would be best sent direct to me. I will ship these to the US if anyone wishes. Please contact me directly at sparczn(No-Spam)@gmail.com Of course price US$150.00 plus US$25 for ship each Thanks Kevin.

[Repeater-Builder] Adding Extra Cavities to Duplexer
I have a Phelps Dodge 506-1 four cavity duplexer. Just recently picked up two additional cavities from someone who was parting out his duplexer... all cavities are BP/BR... Would like to add these to the duplexer to get additional isolation. The original duplexer is spec'd at 80 dB isolation... What do you think I can get with the two additional cans? I realize the insertion loss will be higher.. Any idea how much? The cabling between the cans is still 1/4 wavelength in coax, right?? since I will have to add some cabling...I have seen some discussion in the duplexer info on the site about maybe using a diffrent length cable when adding more cavities... Can anyone comment on all this? Dave WB2FTX No virus found in this outgoing message. Checked by AVG - www.avg.com Version: 8.5.325 / Virus Database: 270.12.26/2110 - Release Date: 05/12/09 06:22:00
[Repeater-Builder] Need MSR2000 PL Reeds or alternate suggestions
Hello Everyone, I'm in need of two 97.4Hz PL reeds for an MSR2000 using the TLN5073A duplex card (one TX and one RX). I haven't been able to located this particular tone elsewhere so maybe someone here could help. Does anyone think sticking with used reeds is still acceptable for redeployed commercial uses (SKYWARN coordination machine on 452Mhz), or should I look at new Comm-Spec encode/decode boards? Thanks, Tony

[Repeater-Builder] Re: Need MSR2000 PL Reeds or alternate suggestions
Hi Tony, I have seen a situation where a section of thin aluminum plate was cut to fit on/over the original PL module. A Comm Spec TS-32 was placed on the Aluminum mount/plate with double sided tape and parallel interfaced with the original MSR-2000 PL module. The plate stood off from the MSR-2000 PL Module PC Board with classic threaded standoffs. Probably the 3/8 or 1/4 inch length 4-40 or 6-32 size were used. Working from memory... I believe the original circuit only used the Decoder section (portion) of the TS-32 but I'm sure it wouldn't be rocket science to make encoder work (taking the encoder gate/mute on/of operation into consideration) on more than one CTCSS encoded tone. One might suggest a couple of contact Emails to the remaining Surplus Radio Dealers... I'd contact Ted at MDM and go from there... also posting a want on various yahoo radio groups like this one. cheers, skipp kt...@... kt...@... wrote: Hello Everyone, I'm in need of two 97.4Hz PL reeds for an MSR2000 using the TLN5073A duplex card (one TX and one RX).

[Repeater-Builder] Re: A Home Brew 224 MHz Repeater Project. - Part 4 (The RF Amplifier)
A Home Brew 224 MHz Repeater Project. May 2009 Part 4 The RF Amplifier First Post May 2, Second Post May 6 - Third Post May 8, This Post May 12, 2009 Moving right along... This text is Part 4 of a description of a recently completed 224 MHz Repeater Project. Pictures of the completed repeater project reside in the group photos section. http://groups.yahoo.com/group/Repeater-Builder/photos/album/1157128983/pic/list The RF Amplifier choice was based on the Hamtronics T301-6 exciter (transmitter) RF Power (output) drive level, which is only about 1.75 watts real world. In reality I would expect the 224 MHz Hamtronics Exciter to output minimum 1.5 watts to a maximum of just under 2.0 watts of RF. I'm happy to report the T301-6 Exciter makes the manufactures rated power level. For lock to talk 100% duty cycle repeater operation I turned down the exciter RF output to about 1.75 watt output per the manufactures recommendation. I'm guilty of using an HT RF Amplifier in this project. An HT Amplifier is normally used to boost the power level of portable HT (aka hand held) radios. The classic entry level HT Amplifier is rated for input drive levels of 1 to 5 watts for a corresponding output of 8 to 25 watts of course depending on a number of situation variables. And of course the HT Amplifier has antenna relay switching based on a detected input RF drive signal. One could easily write an entire article about the pros and cons of using an amplifier with switching relays installed and used but at this time I'm going to avoid doing so... HT Amplifiers are/were made by MFJ, RF Concepts, KLM, Henry Radio and a number of other manufactures. The most common 1-5 in, 8-25 out amplifier models are so similar in most all respects so they easily interchange. In this example I've used an RF Concepts brand but could have easily used an almost exact MFJ Amplifier for pretty much the same results. A few blanket statements for you technical hounds. The TR Relay is rated in number of operations before estimated failure and I would not expect the normal use of the machine to achieve that number for quite a time (years/decades?). In a solar power only situations the RF Amplifier is easily disabled to conserve site energy. One could hard switch the TR Relay with external logic, which would avoid hot switching the exciter. Hot switching is the load or lack there of presented to the driving device (the exciter) while the TR Relay changed the RF Path to the Amplifier input. Hot switching is not an every day in your face problem for most people but you should be aware of it. Another option would be to wire directly to the Amplifiers RF Section(s) bypassing the internal TR Relay. With reasonable operation no blower or fan was used in regards to heat sink temperature... however, a small blower (not fan) would be advisable. Decent blower time on/off management is possible with many of the more flexible repeater controllers. One could also construct and interface a relatively simple blower timer on/off circuit. Please keep in mind the blower doesn't have to operate with every transmission. As a personal preference I choose to toggle the blower on after x-amount of transmit time has occurred within x-minutes of operation. Blower on-time management keeps me from having to listen to blowers winding up every transmission, saves energy and helps to extend the blowers usable life span. I'm not a fan of leaving blowers (and fans) running 24/7. If you plan to use the repeater for linking, IRLP, Echo-link or similar a blower is smart money well spent. A 30 second time out timer also trains the lock to talk type people to listen more often (a good thing). The TR Relay doesn't chatter on and off with loose RF coming back down the Transmitter feed (coax) line because a circulator is installed. So the Hamtronics Exciter RF Output is routed direct to the amplifiers input via some decent mini Teflon type coax. In a previous post I mentioned how surprised I was in regards to the power (signal) lost in even very short sections of regular RG-58 coax so don't cheat yourself by using the wrong type of coax (trying to save a buck). The supply voltage is provided via a fuse block assembly, which will be detailed in the final Part 5 article (text). Just for trivial I'll say I leave the amplifiers front panel control switch set for SSB operation, which only delays the relay UN-key hang time (of the amplifier, not the repeater). No actual mode change is done internal to the amplifier via the FM/SSB front panel switch. The Amplifier output is about 20.5 watts with 1.75 watts drive, which is just fine for this project. The repeater site antenna combiner systems eats almost half of the output power so we see about 12 watts heading to the site master transmit antenna. Part 5 will be the wrap up text.

Re: [Repeater-Builder] (anderson power poles revisited)
Chuck Kelsey wrote: I've had them unplug easily. Had another that if you wiggled it, it would make and break contact. I solder all mine, taking care not to get solder on the contact itself. I went to them after having trouble with some heavy-duty Molex connectors ( one contact got hot and discolored the shell) and, no, I was not exceeding the current carrying capacity of the connector. As far as using the smaller PowerPoles as a standard to insure multiple operators radios being compatible with each other, I find a connector that can be configured multiple ways (like the PowerPole can) to be a poor choice for that purpose. Chuck WB2EDV I was always told the standard was supposed to be the Ford connector, as used on Maxtracs, etc. Most everything I have has those.

As in years past RB will NOT be setup in the tailgating area. (I know, much to everyone's great dismay) My wife Elisha and I WILL be at the show on Friday - all day. I'd love to say what frequency you might find me on, but if things go like last year, I won't even have a radio on me!! For those that REALLY want to get in touch with me, E-mail me privately and I'll give you my cell #. (Did I *REALLY* say that??) We do have plans to stop by Jeff's lounge and hang out for at least a few minuites. (For those that don't know, Jeff's spaces have become the Un-Official RB list hangout whilst at Hamvention) If anyone is willing, we can *TRY* to coordinate some type of dinner on Friday night for list members going to the show. WARNING: It may be a dinner at Bob Evan's in Fairborn or something, but If you're interested, e-mail me. I'll see what kind of response I get and go from there. Most unfortunately, I don't think I can convince Kevin to make the 6hr. drive to join us. :( Be sure and keep an eye open for anyone in a RB hat. (Those that own one should sport them proudly or be summarily shamed into submission) I will also, more than likely, have a RB shirt on, but it probably won't be visible due to the Parka I'll be wearing. (Reminder to get RB logo'd parka for next year!!) Skipp: Sorry, but if I can't remember a simple radio, how am I supposed to remember my helmet tower??
