[Repeater-Builder] Remotely controlling a Arcom RC210
Looking at this thread on Repeater Builders; DSL Repeaters...Curious if folks control or program their controllers remotely? Not by dtmf either. I havent gotten the dtmf control thingy within the program to work thru rigblaster yet. Ideas? Robert

I havent gotten the dtmf control thingy within the program to work thru rigblaster yet. Ideas? Robert I know of one person that uses a packet link over a 420/439mhz point-to-point channel to remotely access the serial port on his controller. Except for the 1200 baud throughput bottleneck it works OK. On another topic... The program available from Scom for their programs does not use a rigblaster - it uses a serial (a.k.a Com) port to talk to a modem (which is uses as a touchtone generator). The modem audio (i.e. the phone line port) is connected either to a receiver audio input port or to the autopatch (if that option is present). Other controllers that do not have a serial port are programmed other different methods. What controller do you have, and how are you trying to program it?
[Repeater-Builder] Re: Remotely controlling a Arcom RC210
What controller do you have, and how are you trying to program it? Arcom RC210 Ken has a dtmf regen thing in the programming software, much like what you described but does it over the air. String of dtmf's are sent and it does it's magic. However I haven't been able to get this to work. Not sure really if many people use this function either. Again I can program it with dtmf's from the radio...no problem. Just TONS to send if your changing several macros. Just thought of using some type of wireless setup. Maybe using some type of ethernet to serial converter? Then put the Linksys setup Kevin was describing? Thanks, Robert

RE: [Repeater-Builder] Modification of Sinclair Q2220E 144Mhz duplexer to 220Mhz
Hi David, I just finished modifying 6 900MHz 10 cavities to use at 440MHz for a 3 channel receive combiner. Sinclair engineers will send you a PDF of such cavity at 220 and the loop length. At first they will be hesitant but they will eventually send it to you. For the loops just make new loops and solder them to the connector. For the internal rod. Unsolder the tower and leave the finger stock alone if possible to.

No problem. But, does the depth of the cavity matter? Do I have to shorten the casing as well? I know in the past when I removed the bottom of the large Q202 cans, the bottom being in place or not had little effect on the tuning.

[Repeater-Builder] Re: Modification of Sinclair Q2220E 144Mhz duplexer to 220Mhz
Hello Dave, The length of the cavity doesn't effect its operation so you won't need to shorten it. Scale the cable harness down to 220MHz. Using a plier, you can work the crimp to be round to loosen it to be reused for soldering. The loops could be made shorter but may not be necessary since the pass to reject and insertion loss is adjusted by the loop orientation. Loop size is not very important if you are able to get a 0.5dB to 0.6dB insertion loss for the pass reject frequency spacing. Don't try to deform the loop while it is soldered to the capacitor - it will break the capacitor. The loop size will determine the spacing apart of the two notches of the Q loop as well.

Re: [Repeater-Builder] WTB: GE EXEC II 66 Split receiver for mobile radio
Thanks Kevin, I am thinking the same thing. All the crystals that I have for these ge's is done on the low split, they work fine, use the HSI and the results are not that great. And yes, the 56 is in the 2 meter band. Was the reason that I wanted to try a 66 split to see if we can use the existing crystal that I have here.

RE: [Repeater-Builder] IOTA Power Supplies
The Iota supplies look and act pretty much identical to the Duracomm DPS series models best I can tell. I have a few 45, 55, and 75 amp models with no failures to date. I was a little leary when I first started buying the Iota units because most of their literature seems to imply that they are more oriented toward battery charging, specifically RV/marine uses, but I've found no reason to consider them unworthy for radio service. The Iota units seem to be available for less cost than the equivalent Duracomm units. On a somewhat related note, Duracomm got onto my $h!+ list a few months ago. I had two older PS-75 power supplies that had failed, one due to poor connection of the wire inserted into the compression terminal which resulted in overheating and meltdown of the molded plastic piece surround it, and another due to a shorted rectifier. Duracomm wouldn't repair either, stating that they were no longer supported, and they wouldn't provide schematics either. I shelved the former, and fixed the latter myself. The PS series Duracomm power supplies were designed and manufactured by Todd Engineering, not Iota, IIRC. --- Jeff _ From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Richard Sent: Sunday, January 07, 2007 9:12 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] IOTA Power Supplies In my opinion, they are very good quality power supplies.

Re: [Repeater-Builder] IOTA Power Supplies
Hello Andrew, The following text below between the --- lines is a direct quote from a post I made on 6-22-05 on this same board. The PS is still working fine! NO NOISE DETECTED! If you practice good engineering practices you should have the same results. I twist all red and black conductors, ground everything, crimp and solder the heavy leads. (And I use the $1000 commercial crimper.) Keep leads as short as possible and the DC leads away from the AC leads. The name of the dealer that I got mine from is Master Techs at 1-800-848-0558, the salesman was Wesley Miller. The dealer is in Marshal, Michigan. They are usually at the Marshal Michigan Swap. They give a discount to hams if I remember right. I bought the 55 amp unit with the external IQ-4 and paid $222 including shipping and tax. I believe the IQ-4 (intelligent controller) is now available built in. It is only needed if you are charging a battery and then only if it is other than a standard lead acid if I remember correctly. 73, Shanon -- A few of us in the Detroit area are using the IOTA supply/charger. We have them hooked to a truck size AGM (Advanced Glass Mat) battery and use this setup as an automatic UPC in case of power loss. Runs all the radios for 48 hours plus. We love them!! Been in use over a year. The beauty of it is the only external part you need to add is a fuse. No isolator required!! After reading the past articles in QST that had used two other brand charger/power supplies, I questioned them as to noise, since we are using them to power our whole base stations. HF, packet, VHF, UHF and laptops. The local dealer sent me one with the promise of a full refund and he would pay the shipping both ways IF I was unhappy with the emitted noise. I found none. The only way I could get any noise was to stick the probe right into the vent holes. I swept it with my IFR AM-FM 1500 and a Tektronix 492. I went with the 55 amp version and the optional controller since I was going to use an AGP battery. Just under $200 if I remember correctly. As any self respecting ham would do, I took it apart. Very good construction. The on board fuses are in line with the DC output. I will be buying more.

Re: [Repeater-Builder] Isolator/Circulator
From a previous message on this group; Many radio communications equipment manufacturers make isolators: EMR, Celwave, Decibel Products, Telewave, TX-RX, and also Andrew, Connecticut Microwave, MECA, REC-USA, and Raditek, and many more. Contact suppliers such as TESSCO or TALLEY for prices. Paul kb9wlc --- Kent Chong [EMAIL PROTECTED] wrote: Hello, Building a combiner now. Frequency is between 400-520Mhz and power is 10W.

[Repeater-Builder] Re: Standard RP71K Repeater
Moving the RP71K up to 900 would be a $#8 ... not in my opinion worth the trouble. These type/series of Standard Desktop repeaters are a pain to service - work on - mod - repair. The GE-MVP 800 goes up to 900 with reduced power. In a few weeks I might let you know how some older midland syntechs work on 900 in repeater service. But the standard repeater is kind of self abuse... I have three or four in service... that love - hate type thing. cheers, skipp n4rpd [EMAIL PROTECTED] wrote: Hello to the group: Recently acquired a nice clean Standard RP71K Repeater, this is a conventional 800MHz repeater that looks to be in great shape. We are looking to try and move it up to the HAM 900MHz band. I can't seem to find any documentation, owners manual, tech manuals, etc... If anyone has any info they can provide, I can pay for copies and postage. Thanks in advance, Rob DeVega, N4RPD Colorado Springs
