Re: [Repeater-Builder] help with sinclair duplexer r101gc
Randy and others, Check out the PDF index on the supporting website: www.repeater-builder.com/rbtip/pdfindex.html I have reciently added some 6M conversion information. I have not used this personally, but it did come from the sinclair factory. It's a bitvague, but you might be able to make some sense of it.Enjoy.

Re: [Repeater-Builder] ArGoSoft Mailing List Server - fixed?
Fellows, I think I fixed it. Someone subscribed a list to the repeater-builder list. I have set that e-mail account to NO E-MAIL.

Re: [Repeater-Builder] PL/CTCSS Filter
The mitrek uses a type of passive filter. It's more of a shunt to ground type of filter rather than a series element. If you look at the PL board schematic closely, you will see where it connects through pin 7 to the radio. The schematic notes (all of the theory of operation we have in this case) says that it is a gyrator, a simulated inductance, that resonates with a .1uF cap to produce a notch at 180Hz. I never found them to work the best, but there is a kind of filter there. If anyone can tell us a more advanced theory behind how this type of circuit works, I think we (or at least *I*) might learn something. In order to use a thru type filter, you will need to break the audio path somewhere. Be sure you feed your filter with a good low-impedance source, and feed a high impedance load with it. Scott M.

Yes, to use the filter, JU201 needs to be removed or is that a problem for you? I am using a Mitrek not a Micor. The Mitrek doesn't have a filter on the PL board.

[Repeater-Builder] HP 8920 Service Monitor Help
My HP 8920 Service monitor has suffered an overpower condition to the Antenna IN connector for apparently it's last time (Accidental of course!!). Does anyone have a "real" component levelservice manual on this Monitor? I have a manual that calls itself an "assembly level repair guide". That's all fine and good.Following it has told me that the problem is in the input/output section (A23). A call to HP for a replacement module sat me on the floor for a few hours!!They want as much for that module as I paid for the whole monitor!!! I'm sure it's a relatively simple fix with (maybe) a common part, but without any board level docs. it's hard to say. I have disassembled the module to look for any burnt traces or parts blown off the board, but everything looks OK. I ran a few simple ohm meter checks, but with a multi-layer board, I can't tell where some of the traces are supposed to go. Has anyone run into this before or knowof a decent person to deal with when it comes to repair. I really on this monitoron a dailybasis, and it's completely usable through the other 2 ports, so I'm not reallyenthused about sending it off to the repair shopfor a few months. Scott M.
