I have a Wacom Duplexer (70 cm) and cannot tune the notches on them, I think the trimmer cap. are bad from a lighting hit so can some one tell the capacltance range of the trimmer cap. (1-10pf or 1-14pf or 2-16pf) Thanks Bill KC5NQ

[Repeater-Builder] Spectra PL tone encode disable?
Our group is intending to use spectra's as link txmitters (70cm) for our remote rx sites. Is there a way to disable the tx pl tone during link tx CW id period? Due to the rf environment at the main site it is a must to run tone. Any help? TNX Greg WG8Z
[Repeater-Builder] Re: FYI: FCC officially issues RO dropping code requirement today
I see know Rules and Order (in fact it has not been released) --- it may come next week -- only thing posted on FCC web site was a Press Release about an RO being written !! Appears to be a 'last minute' decision before congressional change in 2007. FCC commissioners will likely have to testify -- why they are so supportive of BPL -- when power companies take over 8 days to restore power in the Midwest 2 weeks ago -- and the economic argument is non-existent. Also, they are still deadlocked after 5 weeks on the ATT and Bell South merger. w9gb

Re: [Repeater-Builder] Spectra PL tone encode disable?
I don't recall any input on the accessory jack for that function. Sometimes you can program a second mode without PL and change to that, but I don't think the radio will let you change modes while it's transmitting, nor is there an input for that function either. Some MaxTracs have this feature, but it's not implemented cleanly. When the PL is disabled, it throws quite a glitch out to the VCO. The most reliable method is to inject your own PL into the audio stream, rather than rely on the radio to do it. Of course, this is a lot more difficult on a Spectra than it is on something like a MaxTrac or a crystal-controlled (non-synthesized) radio. Spectras are just less versatile in this area. You know how it is: if commercial users don't need it, Motorola makes no provisions for it in their equipment.

[Repeater-Builder] Re: 4W EM Remote
Mike, I have few objectives: 1) Remove a lot of RF from the RACES room, 2) Release two antennas for other purposes, 3) Consolodate operations: one mocrophone instead of many, 4) Allow simple, non-RF interconnection between repeaters. Eventually, remote control could extend to as many as 8 repeaters and 2 remote base stations. I'm also looking at the possibility of remoting packet as well. Bill - WB1GOT I'll maintain backup access via radios but they'll be shared with other use and no longer dedicated to repeater operations. 3) --- In Repeater-Builder@yahoogroups.com, Mike Morris WA6ILQ [EMAIL PROTECTED] wrote: At 08:22 PM 12/17/06, you wrote: I have an opportunity to establish remote control for several of our ham repeaters that are co-locates with our county microwave system.

[Repeater-Builder] Re: FYI: FCc officially issues RO dropping code requirement today
You know, there is no requirement to kil code from the airways. Some people are talking like this is the end of things. NOTHING says there won't be any more code, it is just relegated to the other obsolete and dusty vestages of the amateur radio world. I know there are a lot of folks that enjoy code operation. To them, I say - have a great time with it! It is yours to use and enjoy. There are dozens of other operating modes that are in greater use and are more relevant to today's amateur radio licensee. Why saddle people with learning an obsolete operating mechanism? The FCC acted properly this time. The dooms day sayers are in full foce - but without any facts to back them up. It's time to move the art and science forward - not backward. IMHO Doug KC0SDQ

Well, you will want to use the EM part for PTT and you can also use the reverse path for a COR-based activity indication. Just remember it's all 600 ohm audio, keep levels down so that the max level that can possibly be generated is roughly under 0 dBm, but above -20. And the EM is referenced to MINUS 48 volts, so watch your grounds and BE CAREFUL! It'll knock ya on yer butt if yer not. You won't really need to switch between rptrs. Bring all the audios in to a mixer, with maybe volume controls for each, or try to invent some sort of select/unselect arrangement like is done with dispatch consoles. Then just have a row of pushbuttons for each PTT, mic audio can be connected to all through it's PTT switch (actually a relay would be more reliable).

Laryn K8TVZ Washington D.C.- It was announced today that Kellogg's and the Federal Communications Commission have signed a pact to issue Amateur Radio Licenses on specially marked boxes of Corn Flakes. In this unprecedented move the FCC believes this will not hurt amateur radio but allow all individuals to receive an amateur radio license without having to demonstrate any skills with the exception of being able to use a pair of scissors to cut out their operating permit from the breakfast cereal box. Kellogg's spokesperson commented that they were proud to have been selected by the government to be the issuer of licenses for amateur radio in the US and hope to soon make an agreement with other cereal loving countries. They also expect that will be issuing certificates of achievement for DXCF for confirmed contacts with 100 corn flakers.
[Repeater-Builder] Micor power supply rating, how many amps does it produce
Is there a way to find out how many amps a power supply is from a motorola micor system. For instance a power supply from a 100 watt system? A way to look up the model numbers. I am trying to develope a power supply capable of giving at least 40 amps continous duty that is rack mountable. Currently I have an Astron 70 amp power supply, but would like to remove that amp and replace it with something that is rack mountable, but don't want to incur the cost of buying a new one if the two that I have will work.

[Repeater-Builder] Re: 4W EM Remote
Thanks Jim! You managed to re-fire an old, unused neuron: Dispatch Console! I think there may be one, or parts of an old one in storage somewhere. If I rember correctly, they will interface to nearly anything thanks to a diode and jumper matrix and a mess of relays. Probably be the only thing left working after an EMP event! :-) Then there's always the prospects of Frankensteining an older CallDirector(tm) set. It appears that the county will also be swapping out fairly new Moto remote bases with new units that can simulcast so there may be a remote simplex base or to going into the mix too. Now all I need to come up with is a fail-safe interface for use at the repeater sites. Want to keep it simple and NOT have to get to the innards of the controlers. Just want to break and tap the xmitter PTT and audio lines and be able to route them down and back up the pipe on command (my remote PTT). Sounds like another job for a good old relay! After 35 years with ATT, you would have thought I would have remembered my roots all by myself. Thanks! Bill - WB1GOT --- In Repeater-Builder@yahoogroups.com, Jim B.
