[Repeater-Builder] Re: Falcon Communications 220 Power Amplifier
So make your own tech data for the amplifier. Nothing rocket science about working with Poly-fets. I've built or repaired a fair number of NMR RF Amplifiers using them and there's nothing really super scary about them. As long as you don't go crazy with abuse they should be as hardy as many common fet designs. Look on the web for poly fet amplifiers after first going to the Polyfet Home Page. http://www.polyfet.com/ Some of those Milcom - aka Cresend amplifiers use more traditional fets so you can also resource those brands for more information. You don't have to put RF through the Amplifier to check the devices. Since the max frequency limit of the polyfet(s) might be well above 250 MHz, the same device might work on both the 2-Meter and 224 MHz Amateur Bands. cheers, s. Eric Lemmon wb6...@... wrote: 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

Re: Falcon Communications 220 Power Amplifier ... and to add a bit more in... a quick F1260 polyfet in Google will hit on the device data sheet along with a replacement source from Surplus Sales of Nebraska for $45 each single unit cost. http://www.surplussales.com/Semiconductors/SemiC-RFtrans.html If you have one or more bad fets... you now have a resource to judge the value of replacing the device(s). Falcon may be long gone but fixing an amplifier is fairly straight-forward. Hey Bruce, may I bribe you for a copy of the circuit diagram please? I'll pay for it and buy you a hot dog and soda at the next De Anza (or Livermore) Swap Meet... hint, hint. cheers, skipp skipp...@yahoo.com skipp025 at yahoo.com cruising7...@... wrote: Eric I believe this unit is a Falcon 8252 220 Mhz power amp, 10 watts in, 100 watts out, continuous duty.

[Repeater-Builder] Micor Mobile TLD8262B10 Exciter Question
Micor Gurus, I just came into possession of a Micor Mobile with this exciter installed. The unit had no Channel Elements installed when I got it, so I borrowed one out of another Micor I have just to try the radio out. With a 147.015 MHz Channel Element installed in this exciter, I get no power from the radio, but I do hear the signal in a nearby receiver. I swapped the Exciter (same Part #) from my other (working) Micor into the unknown radio and get good power using this channel element. With the unknown exciter in the known-good radio, I get no power output. Obviously, I've isolated the 'issue' to the exciter. My question is, will this exciter work in the 2-meter range without modification? If so, then apparently I've got some troubleshooting to do. If not, what mods need to be done to make it work down this low? Thanks in advance, Mike WM4B
RE: [Repeater-Builder] Micor Mobile TLD8262B10 Exciter Question

RE: [Repeater-Builder] Micor Mobile TLD8262B10 Exciter Question

[Repeater-Builder] Re: Micor Mobile TLD8262B10 Exciter Question
Based on my experience with radios like the Micor Mobile with the tx band-pass filter and the MSR-2000 exciter... the best way to tune up these units is to find the coil preset information in the Service Manual and start with reseting those items back to the chart indicated height position. Sure you can adjust some coils when moving the exciter small distances from the last operating frequency. But some coils are not simple peak or dip adjustments. They interact with the previous or trailing coil adjustments and should be adjusted per the manual only... re-tweaks just don't do it. In the process of tuning the exciter and related filters you'll sometimes see only slight meter movements as you step up through the chain/process. One stage adjustment of the MSR-2000 is really hard to see initial meter movement. A re-tweak of the exciter won't always show the mentioned small meter movements and it's sometimes very easy to adjust a stage to a wrong peak/dip. So start from scratch most every time. Be sure to use the coil position chart information provided in the manual or your results will surely vary. cheers, s. Mike Besemer \(WM4B\) mwbese...@... wrote: Not lookin' good for the home-team.

Mike, Take the advise that Skipp has given you. In one project I didn't heed the advise of others to preset the coils from the service manual and I was pulling my hair out for days trying to figure out why the exciter wouldn't tune up properly. Do like he says . . . . reset everything back to the chart indicated height position. Then use the manual to tune up the exciter.

I see on the repeater builder web site a mod to pull the PL detect out of the rear of the 7000 to input into the CAT, but I'm not sure how this works. Is anyone using this? I dont' quite get how the PL detect is being done in the repeater, if it's not in PL?

Re: [Repeater-Builder] Repeater Kerchunk
Your kerchunkers are most likely licensed hams. This is an issue as old as repeaters. It's illegal to kerchunk without ID-ing, but there's not much you can do about it. Is the repeater PL access? Use decode on your receiver, and all you'll hear is a quiet squelch break, no courtesy tones, IDs or squelch tails (if it's set up right.)
