[Repeater-Builder] Re: 10 meter Repeater bandplan, National Coordination, 100KHz splits etc
I'd bet the bigger hurdle would be convincing the users to adapt all those individual radio to add tone encoders. There's a lot of ancient hardware in use on 10m. If there's known local activity in the area... people will try to find and use equipment that makes the machine. It's hard to get folks to sink money into repeater use radios for bands that have minimal activity. You can take my converted CB when you pry it from my cold, dead fingers, etc. Most serious CB Radio Operators I know don't mess around with basic CB equipment. Many have advanced HF Radios at home and export type CB's in their cars. If you haven't checked out an Export CB for legit 10 meters then you're missing out. Some of the models are much more impressive (bells and whistles wise) that many Amateur Radios. I once had a converted CB for 10 FM. Added a CTCSS encoder; worked fine. Bob NO6B The low cost 555 based home-brew tone encoder project was originally designed and installed in a Regency HR-212 2-meter radio. http://www.radiowrench.com/sonic/so02148.html Both the encoder and the radio still work fine... although the receiver front-end is so wide it won't work well in a busy metro city but living large in the countryside with an old radio can be swell. If you have an active repeater on in the local area, people will find you if they know about you. cheers, skipp

Re: [Repeater-Builder] Re: 10 meter desense help, split site, high noise floor.
Jim,
I'd be interested to know where in part 97 you find any restriction on FM below
29.5. (Without debating it, of course.) ARRL bandplan, yes, but FCC rules?
Keith, we're also stuck with band-planning on other bands which didn't
anticipate the popularity of FM repeaters. 2m is even more screwed up. Why have
only 600 kHz offset, when it could have easily been double that? Duplexers
would have been smaller, less expensive, worked better, etc.
The answer is nobody had figured out in the early 1960s that FM repeaters would
grow to be the dominant mode on the band. Originally, repeaters used 30 kHz
channel spacing with inputs between 146.0 and 146.4, then a 200 kHz buffer zone
for simplex, and outputs between 146.6 and 147.0. When additional repeater
subbands were added, it would have made sense to go to a 1 MHz split, but at
the time too many repeater ops would have bitched about buying crystals and
retuning duplexers.

[Repeater-Builder] Sinclair Q202G duplexer Conversion
Read the posts here already and wish to clarify a few things. First I am in the process of converting a Q202G from the 160mhz range down into the 2m band, specifically 144.7500/145.3500Mhz. I have found that I will need to replace the harness to do this as it will not tune down that far. 1. I Understand I must make the harnesses at 1/4 wavelength each between the cavities and from the cavities to the antenna T connector. What is the formula for the exact cable length? i.e. 1/4 wavelength of freq * velocity factor of cable = cable segment length? 2. Are the lengths exactly the same for the low and the high sides or are they dependent on individual frequency for each side. 3. Where is the measurement taken? From tip-to-tip of cable or from center-of-T to center-of-T, etc? 4. In relation to #3 I will be using a N-Male/UHF-Female adapter on each can. Then connecting the T to that adapter. Will this affect the cable harness length calculations and if so how? Thanks in advance! Best Regards, Bill - W4RVN

At that length the connectors begin to be problematic, as their lengths become a significant portion of the line. Using N connectors should simplify things a bit, as most of the N connector is air dielectric, the rest teflon. Bob NO6B

That is the proper formula but don't get too hung up on exact lengths. 2. Are the lengths exactly the same for the low and the high sides or are they dependent on individual frequency for each side. The lengths are not highly critical. AFAIK Sinclair only had 2 standard harnesses, one for the low part of the band and one for the high part. The low split harness cables were about 1 inch longer each. 3. Where is the measurement taken? From tip-to-tip of cable or from center-of-T to center-of-T, etc? Between center of Tees. 4.

Maybe or maybe not the length of the cables. However anything that will lengthen the distance between the center of the Tee and the loop will affect the tuning and depth of the notches. Now the key question. Why would anyone want to use a pitifully inadequate so-called UHF adapter or connector on a well designed system that is intended to have N type connectors. Throw out all your UHF connectors and adaptors and go with the proper type N connectors. Save yourself a lot a hassle later with problems related to the UHF connector series. That is just my opinion based on past experience. Others may differ. Burt VE2BMQ
RE: [Repeater-Builder] Sinclair Q202G duplexer Conversion
Bill, This topic has been addressed several times in recent years. There is no formula for the harness; Sinclair makes two harnesses, one with 12 between tees, and another (for the 136-150 MHz split) with 14 between tees. The coupling loops are identical between splits; the harness is the only difference. The harness is completely symmetrical. It may be easier to simply purchase the correct low-split harness from Sinclair, for about $150. The harness is fabricate with Delta crimped tee connectors. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of wpp3 Sent: Tuesday, December 25, 2007 12:35 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Sinclair Q202G duplexer Conversion Read the posts here already and wish to clarify a few things.

[Repeater-Builder] feedline advice
Hello All, I am putting up a UHF repeater in Seattle and have a question regarding feedline losses.The repeater site is on top of a building and the distance from where the repeater/duplexer will be located is less than 25 feet of coax distance away from the antenna mount. Of course I would like to reduce the system losses as much as possible so I'm willing to pay for ~25 feet of 7/8 Heliax. However my question is more about the loss experienced with inter-series connectors in the feedline. The 7/8 Heliax is not very friendly to bend and route into the cabinet for direct connection to the duplexer, so every repeater I've seen has a short chunk of something more friendly like RG-214 going from the duplexer, through the cabinet, and then joins to the Heliax with some kind of N-male/N-male adapter. What kind of signal loss occurs through such an adapter at 442mhz? On such a short run am I losing more signal through a Male/Male adapter, such that I just may be better off running a single segment of RG-214 the entire 25 feet? As far as I can tell, 25 feet of RG-214 would be about 1.28 dB of loss, while 25 feet of LDF5-50a Heliax would be as low as 0.2 dB, but if a single Male/Male adapter causes anything close to 1 dB of loss than it seems like a wash to me...

[Repeater-Builder] Re: feedline advice
Jay is correct. A 25 foot length of LDF4 (1/2 Anrdew) would be good and have about 0.4 db loss. It's also pretty good for felxability. I just picked Andrew since I had that spec sheet handy. Other brands would also be good. Most adpaters will be in the 0.2 db loss area at 450 MHz. Obviously minimize the number, but don't worry about one or two.
