RE: [Repeater-Builder] Re: 220MHz Repeater Power Repair
Jeff, Keep me in mind should you decide that you need to lighten up your shelf... The RF power transistors are listed as Factory Select. Do you know what the mfgr and part no. is or what would work? Thanks Gene WA2IJE Probably some Motorola MRF-xxx type equivalent. I'd probably use a Motorola RF Transistor Data Book to look for a matching power level and case style. I'd also need to know how many stages are in the amplifier...? ... direct drive of 2 output transistors or if there's a single or dual predriver stage before the final sections. I have a new (well, it's been sitting on the shelf for a few years) TPL RXR series 220 amp here. It uses an MRF-646 driving a pair of MRF-648's. This is the same configuration as used in their UHF amps that take 8-15 watts in for 70-100 watts out (though obviously with different component values and microstrip Z/geometry). Obviously, at the lower frequency, the gain is higher - this one is labeled 5 in for 100 out. --- Jeff Jeff DePolo WN3A - [EMAIL PROTECTED] Broadcast and Communications Consultant Yahoo!

[Repeater-Builder] Mastr 2 PA Matching Unit
Does anyone know the best way to set up the Z-matcher unit in a GE Mastr 2 continuous duty PA (I have 3- 110w uhf PA's for a 200watt UHF station)? I follow the service manual and do not get the results I should be getting. With proper drive power, adjust the two variable caps for minimum voltage at test point 1 which is on the matching unit into a dummy load, is the way the book is telling me. Tune for minimum voltage, but I am not getting full power out. Should I be tuning for max power with the least voltage or am I doing something else wrong. TIA for any help... Andy KC2GOW Yahoo!

Well, I have the VHF version of this station. It sounds like the tuning procedure is the same for either. I too, was not happy with the results obtained with tuning by the book. As suggested in a post (I believe by WN3A) these actually are Z matchers, and should be tuned for best efficiency. I tuned these things by slowly and carefully watching the current draw and power out simultaneously. It takes some time, but there are combinations that will yield considerable reductions in current draw for the same PO. You may also have to expand or compress the coil near the capacitors and continue all possible combinations of adjustments. And you should go through each amplifier several times, after making adjustments on the others. All adjustments interact to some degree. I was able to reduce each amplifier's current from 15-16A down to 12-12.5A, with the same PO. To me, that is worthwhile. Laryn K8TVZ Yahoo!

I tuned these things by slowly and carefully watching the current draw and power out simultaneously. It takes some time, but there are combinations that will yield considerable reductions in current draw for the same PO. Yeah, that was probably me. The GE method has an underlying flaw in that the voltage you are measuring is supposed to be representative of the reflected power. However, as the forward power is reduced, it is possible/likely that the reflected power will likewise appear lower at the test point. So, as Andy found, it's very easy to end up with the PA mistuned for something approaching least power output rather than least reflected power. If you have a 200 watt station (100 watt driver feeding a pair of 100 watt combined finals), my recommendation would be to tune the driver into a dummy load first at about 75 watts output, then connect to the Wilkinson divider feeding the finals. This way it's at least pre-tuned in the ballpark. Then tune the finals for best efficiency (using the upper and lower ammeters in the station panel) coincident with the power output level desired. Finally touch up the tuning of the driver PA for best efficiency once you have the finals happy. Keep in mind that the tuning of the Z matchers will vary with power level. Start out well below rated power (say, 100 watts total output at first), make small adjustments to the matching, re-adjust the driver output pot, repeat until you've reached rated power. I have a few of the 200 watt UHF M2 stations, and as Laryn said, tuning with this method results in 3 to 5 amps less current draw per final PA while still maintaining full power output. --- Jeff Yahoo!

Re: [Repeater-Builder] RE: [GE Mastr II] Changing Icoms
At 4/15/2006 21:14, you wrote: Rob, This topic has been covered repeatedly on the repeater-builder list, but apparently not so often on this list, so I'll summarize the postings. It is definitely necessary to send the channel element in for re-crystaling. I disagree with this statement. 5 PPM is fairly easy to achieve via simple crystal replacement, which you can do yourself. Occasionally you'll run into an element that was compensated for a crystal with an extreme curve, your crystal's curve will significantly mismatch that curve. In that case, you can send the Icom in or simply try a different Icom. When you order a bare crystal, intending to install it in a channel element that has been previously compensated, it will *not* maintain 5 ppm. Not true. In most (not all) cases, it will. That's been my experience in working with Mastr IIs over the years. If you want guaranteed 2 or 5 PPM accuracy, by all means send the Icoms in for installation compensation. At the prices ICM charges for this service nowdays (~$100/pair I'm told), it might be worth considering the cheaper alternative. Bob NO6B Yahoo!
