My ARRL repeater guide doesn't list simplex frequencies other than 440.000. What are the agreed upon simplex frequencies? Are they the unused repeater pairs in my area?

I'd like to publicly thank Ian for his 2 1/2 years of service posting the FAQ. Ian came along at just the right time to take over an excellent resource originated by Diana Syriac KC1SP, but technical problems and professional obligations motivated her to transfer the mechanical chores (and most of the editorial ones) to a new maintainer. Ian has been a true professional, coordinating cross-posting to moderated newsgroups like *.answers and rec.radio.info, conducting the co-editor's mailing list to provide broader-based formal feedback and editorial changes, and even leading newsgroup reorganizations to make the FAQ's reflect on an even better set of newsgroups. Like Diana's transition to Ian, this doesn't reflect a "failure" on anyone's part, just a realization that ultimately the FAQ belongs to the readers, and opportunities for more individuals on the net to contribute and become trained in FAQ maintenance techniques is desirable. We'd also like to think that we're not just talking to ourselves, and the overall mission of the FAQ and its content reflects a reasonable consensus of the readership. If you've seen my latest posting of my Elmers Resource Directory, you'll know that I've just made a hurried transition from declining services at UNO to (hopefully) a more stable and better-supported commercial site in the local Omaha area. The demands of maintaining the Elmers list (including working out the bugs and slightly different interfaces at the new site), reading and participating in news discussions at a leaf site (which is running 4-7 days behind), as well as personal and professional obligations, means that I can't in good conscience take over the FAQ myself. However, I'm willing to continue to participate as a co-editor and contribute to the FAQ's ongoing maintenance. If you have *any* interest in pursuing Internet information projects, and would like to learn more about automated posting techniques (or even Unix shell programming in general), please drop us a line. We'd like to see this valuable resource continue for some time to come. 73, Paul W.

ICOM must have changed their policy on helping hams out with technical issues. Quite the contrary, ICOM sent me a photocopy of the schematic and the suggested taps points needed to do 9600 bps. Ron Parsons W5RKN came to my rescue and has a very eligant mod that requires only one solder joint to the main pcb board. I include it below. I have done this mod myself and it works fine. I'd be happy to answer any questions you might have concerning the mod. Steve N7HPR (srbible@nps.navy.mil) -----------------------8<------------------------------------------ Below is a more complete description of my mods. Yes, please share these with anyone you feel like. I don't need the MAIN board pring as I have one in the 970 Service manual. Thanks anyway. Ron W5RKN ======================================== Icom IC-970 9600 baud FSK Mods The following describes mods for 9600 baud FSK for an Icom IC-970. The mods require NO soldering or cutting on the IC-970, and are thus easily reversible. Icom suggested mods for 9600 were: * TX mod input at collector of Q59 on the main unit. * RX Main at DET output in J29 (main unit). * RX Sub at TSAOS output in J9 (main unit). I made slight mods to Icom's mods: * TX mod input at collector of Q59 on the main unit. This is available at the top of R51 with a micro clip. Ground is at the top of R60 with a micro clip. These resistors are about 3" back from the front of the Main unit and 2" from the right. The micro clips were attached to a length of RG-174 mini coax. No mods to board! The leads of the resistors appear to be painted. Scrape the paint off with a small, sharp knife (a small mod). * RX Main output at TSAOM at J29 (main unit). Available on P85 (tone squelch option socket) under the top cover. * RX Sub output at TSAOS at J9 (main unit). Available on P87 (tone squelchoption socket) under the top cover. Two lengths of RG-174 mini coax were connected to a 6-pin headers with the center conductor on pin 4 and ground on pin 3. The headers were covered with heat-shrink tubing. The headers plug into P85 (MAIN) and P87 (SUB). The three coax cables were routed to the back-right of the IC-970 case. The two TVJ hole covers were removed and replaced by two dual RCA jack boards. These boards were attached with a small bolt through the hole for the TVJ screws. Thecoax was attached to three of these jacks.

Actually, I would venture that since the International Morse Code test for a 2nd Class Radiotelegraph Operator requires 0ne minute out of five minutes of solid copy at 16 WPM coded groups and 20 WPM plain language, that one is not considered *proficient* until one can handle the minimum requirement for a 1st Radiotelegraph ticket, which is 20/25 WPM *with ease* (and I'll bet the average operator can handle 25/30 with ease, maybe higher). It's an acquired skill, to be sure, rather than something requiring superior intellect (no put-down intended by that), but it sure is a *neat* thing to do well. (|_|) Paul H.

Hey, in the UK, they give "2E" calls to >their equivalent of "No-Code Tech"s. Errrm - I believe the no-code tech is a little more like the UK's Class-B license. The 2* series is given to Novices, 2*0 are class A Novices (VHF/ UHF with HF) and 2*1 are class B Novices (VHF/UHF only). The * depends on where in the UK you are, and is similar to the G* prefix. The real confusion arises when you have a club station. They have different G* prefixes, and I can't remember all of them. Sorry to all those GD, GJ and GU clubs! Novice call Full call Club call Country 2D GD Isle of Man 2E G GX England 2J GJ Jersey 2M GM GS Scotland 2U GU Guernsey 2W GW GC Wales And on top of that, there's the good old GB special event prefix. With a full call or a club call, the number after the prefix indicates the class of the license. A 2-letter suffix is always an A license, and was issued before the second world war. A three letter suffix uses the following numbers to indicate an A or B license: Class A Class B 0 1 2 6 3 7 4 8 The number 5 with a three-letter suffix used to be used for reciprocal licenses (and isn't any more), and the number 9 is for experimental licenses (please don't ask me what this means!). Current licenses are in the G0 and G7 series, and once G7 has finished it is planned to use G5 for class Bs. And I bet you thought it was going to be easy!

On the other hand, a standard envelope put inside a business envelope plus a dollar bill plus a QSL card weighs almost EXACTLY 1/2 ounce so it gets one unit of International Airmail postage on this end. Using bigger envelopes will raise that cost for us. Why can't DX stations get smaller QSL cards? We dont care about pretty pictures (well I dont) or monster fold-outs. Buy generic QSLs. It should be much cheaper for you too. Here, we can get the generics for about 3 cents each. Is there some aversion to the smaller size QSLs popular here in the states? Maybe no foreign printers can make such sizes? --- ------------------------------------------------------------ Bob Levine KD1GG 7J1AIS VK2GYN formerly KA1JFP levine@mc.com <--Internet email Phone(508) 256-1300 x247 kd1gg@wa1phy.ma <--Packet Mail FAX(508) 256-3599 ------------------------------------------------------------ ------------------------------ Date: Thu, 1 Sep 1994 22:25:00 GMT From: hookup!yeshua.marcam.com!MathWorks.Com!europa.eng.gtefsd.com!howland.reston.ans.net!sol.ctr.columbia.edu!usenet.ucs.indiana.edu!frank_reid.electronics.indiana.edu@ames.arpa To: info-hams@ucsd.edu References <31AUG199403591589@reg.triumf.ca>, <33l3kp$187q@ns2.CC.Lehigh.EDU>, om Subject : Re: Is the moon reflective of radio waves?
