[Repeater-Builder] All Band Repeater - HUMOR
I waited to post this until the auction had ended, but now decided to send it so we can all learn: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemssPageName=STRK:MEWAX:ITitem=270369626907 or search for ended item 270369626907 I especially like the part where he says This is an amazingly sensitive receiver. We have noticed little to no difference in sensitivity as to compared to a single band receiver...; seems like a lot of us have been knocking ourselves out for nothing.

Re: [Repeater-Builder] License renewal
Don I did mine on FCC.gov recently; I'd give the site high marks for ease of use. First thing you will have to do is apply for a FRN number. You will need a password. When that's set up, the rest is easy, just log on and check the boxes. I agree, I don't see any reason to go with the third party outfits for a ham license. Bob U.

How easy / hard is it? Does anyone out there have a step by step instruction list to use as a guide? Was fairly easy for me, but I've been around computers for a while. Once you get an FRN number for the License in question, it is mostly point and click, iirc. I think it didn't cost me anything to renew, and I got to keep my original date of licensing (which makes it very easy for me to remember since it's popular number combination). Or, is there a web site out there that can help me? No idea, I did it on my own. I'm not looking to use a 3rd party provider if I can do this alone. I wouldn't use a 3rd party provider anyway. Unless it was a commercial license. There are certain hooks there that it would be best to seek appropriate commercial assistance with. -- Kris Kirby [EMAIL PROTECTED] The illegal we do immediately.

Re: [Repeater-Builder] GE icom question . . .
Don Before you order crystals, I think you've got a little more homework to do: those two frequencies are pretty close together, so you will need good duplexer. Are those frequencies legal to use for repeater service; I realize this is not the place to discuss rules, but I think those are FRA frequencies, and I know nothing about how that works. By the way, I recognize your name from the Pacific Locomotive Association list; I'm a (mostly) silent member of that organization too. I have a pretty full plate at the moment, but I do have an HP8920 service monitor and some experience (trustee and technical staff of AA6BT/R, 146.115+) that might be helpful; let me know off list at [EMAIL PROTECTED] or [EMAIL PROTECTED] Bob U.

What about the 5C? since I understand it's just for freq compensation, can it be left as-is, or does it need to be reset for somewhere around 160? How much $$ am I looking at? I looked at the International Crystal site but couldn't find any icom reference. TIA Don Yahoo!

RE: [Repeater-Builder] Re: Motrac / Solid State Tubes
There was a brief moment in time in the mid 1970's that Teledyne made solid-state replacements for the 6AK5 and the 12AT7 called Fetrons; they were essentially high voltage depletion mode JFETs. The main customer was the phone company, and when they had replaced all their tubes, the business dried up. (I was at National Semiconductor at the time working on a similar device). I don't think this has anything at all to do with the Motrac radio.

Re: [Repeater-Builder] Fuses on power cords
My bet would be that the black wire fuse is there for positive ground vehicles, a vestige of times past. In that case, the black (negative) wire is hot, and you would need the fuse there. Bob U. AA6BT At 07:20 PM 1/7/04, Ralph Mowery wrote: I'm caught in the middle of a couple of feuding technical experts on a probably trivial issue. Some Mobile radio power cords are fused on only the positive line. Others are fused on both lines. One's logic is you only need one fuse. The other maintains their communications shop lost all the radios with only one fuse to a shorted power supply and none of the dual fused radios were effected. The one fuse expert says that is BS and the other is lying. What is the collective experience/knowledge on here for this topic? Thanks in advance for your thoughts 73 Budd It all depends on the radio and how it is wired. Assumming a standard 12 volt negative ground car. If you go directly to the battery with both leads and you loose the normal car ground to the battery , then all the car's electrical requirements try to go through the radio's groundwire and can fry the rig if it is not fused in the negative lead. If you do not go directly to the battery with the radio's negative wire but hook it to the frame of the car then this will not hapen. Yahoo!
