[Repeater-Builder] Homebrew low power Repeater

Hello: I would like to build a low power 5 watt crossband repeater for 2m/440 use. I recall seeing this set up using 2 HT's, also 2 mobile rigs. Has anyone built something to suit my needs, or are there kits available ? Thank you 73 de Fred W1POP

[Repeater-Builder] MSR 2000 simplex base station conversion to repeater

I have an MSR2000 half-duplex base station that was removed from railroad service (161 MHz). I would like to convert it to a repeater for one of our local volunteer fire departments. Does anyone have alist of boards required to make the station act as a full duplex repeater. The output will be i

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

Paul I have recently had to deal with the same problem. Note if the noise goes away when the antenna is wet for frozen. If this is the case try selectively spraying elements with water while whacking the antenna with a rubber hammer. I will leave the mechanics of doing this up to youHI.

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

Well the 125 ohm quarter wave info sounds reasonable. That would imply the actual impedance of the folded dipole is in the vicinity of 300 ohms. I think my strategy at this point is to test each element by itself. I'll have to actually put each one on the repeater and check for noise as that's

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

The matching section inside the loop is a 1/4 wavelength of RG-63B 125 ohm coax. The overall outside diameter is the same as RG-214 but the dielectric is semi-air (like a large version of RG-62 93 ohm coax) and the center conductor is quite small, like RG-59. I have a few hundred feet of RG-6

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

Sounds like something in the harness went intermittent. To get at the inner element connection, you'd need to cut the shrink tubing on the outside of the element. That should gave you access to the connection point of the 125-ohm matching section that is spliced to the RG-213. You could then pul

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

That's what I thought Chuck. Thanks! I haven't yet decided whether I want to rip the heat shrink tubing off an element and disassemble it to see what coax is inside, which is why I asked. I was sort of contemplating whether it might be possible to replace all that coax with RG-214 in an attempt

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

There is a 1/4 wave impedance matching section of coax (125?) inside the element. The matching section is stagger tuned from the element itself. That's why it is more boadbanded and why you see two return loss dips. Chuck WB2EDV - Original Message - > > I wonder if anyone knows what (

Re: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

Mike, Thanks. That is interesting. I don't recall hearing about this with dipole arrays before. What is the failure mechanism? Deterioration of the coax due to repeated slight flexing? The antenna was supported bottom and middle. Paul N1BUG Mike Mullarkey wrote: > > > Paul, > > > >

RE: [Repeater-Builder] Sinclair dipole array premature failure (noisy)

Paul, I have a question as to how you are mounting the antenna. If you are not top supporting the antenna and mounting it on top of the tower that would explain why as to you getting noise in your transmit signal. Same goes for DB antennas especially the DB224 being so long and not top suppo

Several weeks ago I posted about my ongoing battle with "duplex noise" on a 2 meter repeater. I have now found a big piece of the problem (maybe all of it) but I'm a little surprised. I am wondering if others have had similar experiences. Two years ago I put up a new (well... NOS, actually) Sin

[Repeater-Builder] Re: SyntorX Repeater

You cannot make a repeater out of a single Syntor X, they are not able to be duplexed. You need a PAIR of Syntor X's to make a repeater. One being the receiver, one being the transmitter. So then the receive antenna connection just goes to the front of the receive radio.

I think that you better consider putting harmonic filters on your repeaters. Doing the math, your 2nd harmonics fall on 294.00MHz and 294.45MHz. A quick search on the Internet shows that the US Air Force has a frequency allocation of 291.800 to 296.650MHz. The least that you should do is che
