[Repeater-Builder] Re: Icom IC-F221S
I've personally used both the F121 and F221 radios at reduced power levels, and they seem to work really well. We're using VHF and UHF radios connected together as a linked VHF receiver, talking back to the voter at the VHF tranmit site. We reduced the power on the UHF link transmitters to 1 watt or so... You will need the software (shows up on the programming distribution for the radio) Jim WB8AZP --- In Repeater-Builder@yahoogroups.com, Cort Buffington <[EMAIL PROTECTED]> wrote: > > Does anyone know if they can be turned back to the 1-2w output range > reliably? > > 73 DE N0MJS > > -- > Cort Buffington > H: +1-785-838-3034 > M: +1-785-865-7206 >

[Repeater-Builder] Shameless customer recommendation for Expresspcb (Express PC Board)
Shameless customer recommendation for Expresspcb (Express PC Board) This week I had to quickly produce three different circuit boards for a really smoking hot commercial radio project. The kind where the customer is asking "why hasn't it already been completed?" type project Based on previous experiences with cost, quirky supplied free software and my preference for other industry standard CAD & PCB Programs I never much enjoyed using the online features of Expresspcb (aka Express PC Board). Well all that has now changed Their free software now seems to be much improved, really easy to use and doesn't seem to have any of the previous "punch the clown face" learning curve to it. So . If you've ever wanted to crank out a pc board for your next repeater electronic project fairly fast & easy, I can now recommend you consider the express pc board company path. http://www.expresspcb.com/ If you're cruising around the net with some spare time it's well worth the effort to check out the free schematic and circuit board software and production services. That is all Cheers, s. ps: don't have any relationship with Expresspcb other than being a very happy customer pss: other group members might chime in with their experiences using the various pc board mfgrs.

Remember those Glenayre 97 series lowband amps that you got from me that were on 33 MHz? I think you put them on your 10m repeater. Anyway, after looking at the docs, I found that the PA strips were broadband 30-50 MHz (though the driver board isn't broadband), so I modified them to work on 6m. I bypassed the driver, replaced the "twisted wire" hybrids with Wilkinsons (the balance on those TW hybrids isn't very good anyway), and reworked the harmonic filter. Easily does 400 watts on the high end of 6m with good efficiency (driving it with about 70 watts in from a Mastr II). Just an FYI in case you come across any more, I'm down to my last few. --- Jeff WN3A
[Repeater-Builder] Re: 25 Ohm Teflon Mini Coax Cable
Skipp, the PA modules did not work at 29 MHz, tested individually into a dummy load. I had a chance to play with them yesterday, and as it turns out, there is no need for additional transformer cable length. I got each module to put out close to 300 W while drawing just under 7A of current per transistor, without any bias. I added an inductor in parallel with a 75 pF capacitor across the drains, and increased the coupling capacitors to 1500 pF from 1000 pF and added 130 pF (25%) to the transformer input. That was it!!! Hopefully the combiner and low pass filter will work. The amplifier control board has problems that I'll have to tackle after getting the PA working on 10 Meters...

It was used in a number of Motorola application notes (ANxxx series bulletins) in amplifiers such as yours. The Quintron amplifier boards may even be based on one of those designs. Microdot was bought out by Tyco a while back, and I think they discontinued the cable line and now only make connectors and pre-assmebled cables. However, I stumbled upon: http://www.communication-concepts.com/Coax_wire.htm They have a Microdot 25 ohm coax. You might call them and see if it's the right diameter. --- Jeff WN3A
