Re: [Repeater-Builder] Re: Quieting duplex noise from a tower
I dont know anything about this particular Tower or how and when it was put up. if its a sleeved tower like a Rohn 25g or 45,55, Universal. I always apply Lithium Grease at the joints. This Helps putting up and taking apart towers in the Future. this also a creates an Electrical conductivity between sections to prevent noise. maybe you can still get some and pack it into the joints may help. Just a shot in the dark for Future tower erections.

However, I haven't tried this using VHF excitation, but I've used the same technique to find all kinds of other broadband noise sources. The local power company uses an AM receiver operating in the VHF range (I think I was told it was around 110 MHz) to locate bad/arcing insulators, fuses, etc. on primary lines. Thanks Jeff. I will try that, and also inducing vibration in the tower structure(s) by wrapping it with something as soon as I can. Maybe I will get lucky and find something. If I don't find any specific problem areas, I'm leaning strongly toward trying Phillystran guys when I can come up with the $$$ to do it. I appreciate the input from everyone on this problem.

[Repeater-Builder] Recomendations on T band duplexer
Title says it all. We are putting up a T-band UHF system using a range 4 Motorola Quantar (490-520MHz) with public safety grade infrastructure. System will run mixed-mode (NB/FM and P25) Our VHF UHF systems use Sinclair cavities and IMD panels with great results. However, I need to provide multiple sources. We have an RFP out to Telewave, and RFS via Tessco. Is there another vendor/OEM we should be looking at?

RE: [Repeater-Builder] Recomendations on T band duplexer
TX-RX would be my suggestion. My only pet peeve with TX-RX duplexers that on the duplexers that use garden variety 4 cavities is that they have BNC connectors instead of type N. If you opt for their Type N connector upgrade, you just get three BNC to type N adapters. Their larger cavities/duplexers use type N. Otherwise, I really like TX-RX, and spec them for most projects. If you need model numbers let me know. If you want any Celwave 526 6-cavity pass/reject duplexers in very good condition on T-band, I have a couple of used ones if you're interested, but I'm guessing you only want new for this application. --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of rahwayflynn Sent: Saturday, March 14, 2009 10:56 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Recomendations on T band duplexer Title says it all.

RE: [Repeater-Builder] Re: Recomendations on T band duplexer
28-69-02A (or B), garden-variety 4 4-cavity pass/reject, fixed loops, BNC connectors, the typical duplexer for 3 MHz split applications. The only difference between A and B is the mounting brackets (one is front-mount, the other has added brackets for rear-mount). 28-69-01A for 4-cavity 6-5/8 diameter pass/reject. Adjustable coupling loops - can be set for less or more coupling to adjust insertion loss versus notch depth/passband performance or for splits less than 3 MHz. 28-69-04A same as above, except 6 cavities. Overkill for most applications, but for those that want more... By the way, if anyone is in the market for any TX-RX hardware, email me direct, I have to put in a large order in the next couple of weeks, very good discounts available. --- Jeff WN3A

[Repeater-Builder] Falcon Communications 220 Power Amplifier
I inherited a bunch of 220 repeater equipment, among which was a rack-mount Falcon Communications MosFET RF Power Amplifier built in Newport Beach, CA. Handwritten on the label is 220 MHz, 4-112A, and Rebuilt. The amplifier has two Polycore F1260 transistors working in parallel, and the input jack is marked 10 Watts Maximum. I believe that it is rated at 100 watts output. I know that Falcon is out of business, and I suspect that a previous owner may have modified this amplifier from its original 2m band to work on 220. Without any tech data on this unit, I may be wasting my time trying to find out what's wrong with it. I'd like to hear from anyone who has information or suggestions about this amplifier. 73, Eric Lemmon WB6FLY
[Repeater-Builder] Re: Micor Card needed - TLN1251A
If you can't find the TLN1251, you may find the TLN1250 repeater Control Module. It is the EXACT same board, same frequencies (1550 and 1450), same pinouts, etc, as the PL board, it is just labled different on the front. I think the only difference was the slot you plugged it into, and setting of any jumpers for the functions you want. I think the Repeater module is more common to find.

I'm sorry. ;) Handwritten on the label is 220 MHz, 4-112A, and Rebuilt. The amplifier has two Polycore F1260 transistors working in parallel, and the input jack is marked 10 Watts Maximum. Ouch! Seriously, I'd replace those FETs before you do anything else with it. The early Polycore FETs were a known weakness in those amps. I believe that it is rated at 100 watts output. I know that Falcon is out of business, and I suspect that a previous owner may have modified this amplifier from its original 2m band to work on 220. I doubt it, as Falcon did make 220 amps. Our club has one, which I believe also needs repair. Without any tech data on this unit, I may be wasting my time trying to find out what's wrong with it. I'd like to hear from anyone who has information or suggestions about this amplifier. Replace the FETs it just might work, though I've never known them to be very reliable (probably due to the aforementioned FETs). I probably have a manual for it somewhere but it might take me a while to locate it. Bob NO6B

Re: [Repeater-Builder] Falcon Communications 220 Power Amplifier
Eric I believe this unit is a Falcon 8252 220 Mhz power amp, 10 watts in, 100 watts out, continuous duty. Production date was around 1989. It uses F1260 devices and a couple of 2N7000 devices on the control board. The rack panel dimension is 8 3/4 x 19. If this is the hardware you have and you need an instruction manual with schematics, I have one for you. Rgds Bruce K7IJ In a message dated 3/14/2009 3:49:44 P.M.
