Hi Patrick-- I also have a 2 meter AM radio, a Gonset Communicator IV. I don't have any crystals for it yet, but I'm hoping to score a couple in a trade. There is a person out here locally who collects older AM tube sets. His name is Jim Beeson. He was selling some of his collection (duplicates) at our local ham fest last weekend. I was talking with him and he doesn't seem to have a power cord wired up for his Gonset Communicator IV's and he offered to trade me a crystal or two in exchange for him borrowing my power cord so he could duplicate it. Sounds like a deal that _I_ won't be passing up! I want to get my Gonset on the air and maybe get my father-in-law going with an AM set, too. I don't think an informal 2m AM net will catch on here in Santa Rosa, but who knows? 73, Ken Santa Rosa, CA. -- ____________________________________________________________________ | Ken Harrison | Moosehead: Great beer! | | N6MHG | | | harrisok@sonoma.edu | ...and a new experience for the moose! | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ------------------------------ Date: 24 Sep 1994 21:45:59 -0600 From: mnemosyne.cs.du.edu!nyx10.cs.du.edu!not-for-mail@uunet.uu.net Subject: Does anyone use 2M AM? To: info-hams@ucsd.edu Hi, Yes, this is a serious question :-). In October '92, I became the proud owner of a Hallicrafters 2M AM radio (I forget the exact model number). At any rate, the price was good, and I needed something to play with :-) The only problem is that in the two years I've owned it, I've made a whopping 0 QSOs with the thing.... barring a test-run that I made with it, which was one-way. Obviously, I'm not planning to get a "lot" of use out of the thing, but I would like to know if anybody else has any experience with VHF AM. Anybody want to confess? Incidentally, I wouldn't mind picking up another older (tube-based) 2- or 6-meter radio, so if anyone has one collecting dust, feel free to let me know :-)... particularly one that would do CW, but voice modes are definately okay, too! -- Patrick (KB8DGC) ------------------------------ Date: 25 Sep 1994 03:48:48 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!overload.lbl.gov!agate!msuinfo!netnews.upenn.edu!netnews.CC.Lehigh.EDU!panda@network.ucsd.edu Subject: Looking for Hamfests To: info-hams@ucsd.edu Hey, I'm currently awaiting the arrival of my technician license - am not affiliated with a club, or the ARRL yet [am waiting for my callsign to arrive in the mail] Can anyone recommend a source of information regarding hamfests in the Southern NJ/NY/Eastern PA area? I really like going to these things - but I just don't know how to find 'em. For anyone living in NY, I heard about one tomorrow morning at the Lincoln High School in Yonkers, NY - and one in Queens, NY the following Sunday - if anyone has any info on either please feel free to mail me...thanx in advance 73, Joe --- ------------------------------------------------------------------------------- - Joseph Herman |Thought is useless unless accompanied by action- - herman@yu1.yu.edu |Action is useless unless preceeded by thought - - a196@lehigh.edu | - - slammy@chop.isca.uiowa.edu |EMT, postpunk, ham radio, fencing, 'blades - ------------------------------------------------------------------------------- ------------------------------ Date: Fri, 23 Sep 1994 23:36:05 GMT From: dsinc!spool.mu.edu!howland.reston.ans.net!cs.utexas.edu!chpc.utexas.edu!news.utdallas.edu!corpgate!bcarh8ac.bnr.ca!bcarh8ab.bnr.ca!bcarh189.bnr.ca!nott!cunews!hydra.@@netnews.upenn.edu Subject: W&W Associates To: info-hams@ucsd.edu DARRYL LINKOW (darryl.linkow@ledge.com) wrote: [stuff deleted] : Total time from placement of order until receipt is expected to be : two and one-half weeks!

However, I usually don't get upset unless it takes over a month for a mail order purchase - but that's me. Anyway, the point of my post is that the fnb26 equivalent I ordered arrived, and works as advertised (I measured the capacity). The plastic on these packs usually looks a little cheesy, and this one is no exception - sink marks, texturing not quite up to snuff. Also, mine arrived with a small, cosmetic only, crack in the plastic. I guess it makes little difference if the radio is in a case. Don't expect it to look as perfect as the one from the manufacturer of your HT. Was it worth it? Well, This might only be meaningful to Canadian readers, but It cost me CDN $73.80, including currency exchange, all taxes, handling fees, etc. It would have cost a grand total, delivered, CDN $151 to order a "real" fnb26 from a retailer in Toronto (and it would have a capacity of 1000mAH vs 1200mAH for the w&w unit). So, provided it lasts, I'd have to say yes, at half the price, it was worth it. YMMV.

See my article concerning the mid-70's worldwide transition from AM to SSB on the maritime MF band. And note that shipboard radio equipment prices rival that of aircraft. ********************************************************************** Jerry continues: >Cars are replaced every few years, and end-users of land-mobile (typically government/taxi/police/fire) buying cars/trucks can make that switch to new radio technolgies with little or no economic impact. Not so with airplanes.
