Re: [Repeater-Builder] Johnson question
While I don't have the schematic I do have the pinout. Here it is: 1 -- 8 volt 2 -- Clone 3 -- AFO 4 -- PTT 5 -- MIC Earth 6 -- MIC 7 -- GND 8 -- Hanger I picked up one of these off of E-bay for the very same purpose so please let me know how you make out. 73 Dan It's modular and the box says it's for the 7600 radios. -- Dan Simmons KC2BEZ President North Country Amateur Radio Club W2LCA

[Repeater-Builder] IFR 7550 Schematic Required
I am in need of a schematic for the Processor PC Board Assy of a IFR 7550. It is labeled as figure 5-16 Sheet 2 of 2. The diagram I have is too small and impossible to read the pin #s or any of the text. If I could obtain an exploded view of this schematic it would be greatly appreciated, Dan

If I could obtain an exploded view of this schematic it would be greatly appreciated, Dan It may come out blurry, or it may do what you need, but take the book to someone with a scanner and have them scan and enlarge that section. In my case I had a photoreduced schematic pasted inside an equipment case. I dissolved the glue and floated it free, then scanned it at 600dpi and printed it, Came out a little blurred and pixelated, but a helluva lot more readable not something I'd put in a repeater-builder.com article without a lot more digital massaging. If you don't have (or know someone with) a scanner you can go to the local FedEx-Kinkos shop,... Mike WA6ILQ
Re: [Repeater-Builder] Motorola Test Set(Panel) Model TEK 5f
Thanks Neil for your Help. Went to Fort Wayne Hamfest today picked up an Relatively new Motorola test set Model S1059A, with the cable plus Motrac extension for $60.00, which is what I need. Hope to get the Micor extension cable in the future. Wesley AB8KD
[Repeater-Builder] Re: GMRS UHF Ham Repeaters Sharing an Antenna
Get one of Sinclair's offerings similar to this model. It will take care of the the broad frequency range problem. http://www.sinclairtechnologies.com/catalog/series.aspx?id=280 Sometimes the obvious problem isn't a problem at all. Dan N8DJP 4c. Re: GMRS UHF Ham Repeaters Sharing an Antenna Posted by: Eric Lemmon [EMAIL PROTECTED] wb6fly Date: Mon Nov 13, 2006 7:01 pm ((PST)) Bob, Most of the posted replies seem to ignore the obvious incompatibility issue: GMRS and 70cm Amateur transmitters operate in different bands! Generally, a repeater antenna should be resonant at the transmitter frequency, since the receiver is usually much less picky. So, the issue is really one of finding an antenna that is equally efficient at a GMRS frequency of 462.575 MHz as it is at 444.200 MHz, and THEN finding a way to properly match the antenna for two disparate services. I am not aware of any antenna that will work efficiently on two such widely-spaced frequencies. Even though it may be possible to jury-rig two repeaters so that they can share an antenna that is a poor match to either, is this a good idea? A properly-engineered system would likely use two antennas, one for each system. My concern is that the respective duplexers will not be driving similar or even properly-matched loads. I guess I'm just not used to solving complex design issues with a cheap 'n' dirty solution... But hey, it's worth a try, right? Please report the results. 73, Eric Lemmon WB6FLY - Everyone is raving about the all-new Yahoo! Mail beta.
