In the Atlanta area repeaters are not very busy (some not at all). Anyone listening to 2 meters on Saturday night would hear CW, SSB, Packet and very few FM QSOs. I would think the ARRL would try to get more activity on the entire 2 meter band before trying to cut the bandwidth of FM. Wonder what happened to NBFM? I remember 10 meters as late as 1959 was full of stations using NBFM. This takes up no more space than an AM signal. I remember 5 kcs was touted but I think its 6 kcs so this is a reduction of 9 kcs. The FCC and DOD are both champions of digital but until someone decides on no more than 2 digital modes as a standard this effort will be spread to the wind. I made a few contacts on PSK31 and got berated by the Pactor gang. Yikes almost a replay of the AM versus SSB of the late 1950's. RTTY?? I looked into this in one of the many contests and having a screen full of stations calling and selecting the one to work is almost not amateur radio. Digital voice and the earlier narrow band voice pushed by Henry Radio never caught on even in the DOD circles. I think the ARRL should push for more usage on 2 (get rid of those locked repeaters), NBFM if they are serious as the technology already exists, and settle on a digital standard. Otherwise this is a big waste of time.

Hell, you don't need to be a techno-wizard to know that. Look at how good Congress is at clogging drains.

Except that with regard to RATT or RTTY, if you were looking at a monitor, that wasn't RTTY. Digital voice on the ham bands will turn out like digital TV. Fortunately we did not (yet) have a hurricane in Houston this year. But when we have the next one, based on experience and tests, most of the city will be without TV weather coverage. We haven't been especially effected by the shift so far, as we are on cable. But I bought a small digital portable to replace the analog portable that performed well during Rita and during Ike until daylight when I went out and started up our standby generator and switched the big TV to the outside antenna. Based on brief tests during moderate thunderstorms since, that is not going to work next time. Like Direct TV, enter rain, exit TV reception.

The shift to narrow-band, commercial or ham, is about forcing the sale of new gear. Period. All the "technical" and "bandwidth" excuses are just so much smoke-screen voodoo. I'll bet there aren't ten markets on the entire planet that actually need all these "extra" channels, if that many. There's so much spectrum wasted by stupid mis-allocation and "turf" squabbles (especially for government) that, if you could re-allocate by actual need, you could do it all with 15 KC FM and have TV channels left over. I remember using the freq. allocation book for the DOE. We had HUNDREDS of exclusively allocated freqs. In 15 years, we used a couple of dozen and, if you discount the rarely used ones, which could have been rolled-into other channels without a hitch, the count would be about ten. ------------------------------ Message-ID: <30641146.1254363115421.JavaMail.root@elwamui-norfolk.atl.sa.earthlink.net> Date: Wed, 30 Sep 2009 22:11:55 -0400 (EDT) From: Richard Dillman To: Old Tube Radios Subject: Bob Shrader visits the MRHS Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Famed radioman Bob Shrader (W6BNB) did us the great honor of participating in Services of the Church of the Continuous Wave (where pastry and coffee are served) at the Bolinas transmitter station on a recent Saturday. This was made possible through the great generosity of Dan Cron (W6SBE) and his brother Ron Cron (W5CFN) who graciously drove Bob to the site from his home in Sebastopol, CA. Bob's name may resonate with many. He literally wrote the book, Electronic Communications, on radio and electronics along with many other books on electronics and firefighting. Steve and I had our copies of Electronic Communications with us for Bob to sign, which he did to our great pleasure. Bob visited Bolinas in the 1930s and saw the great Alexanderson alternators in service in Building 1. He was first licensed in 1931 and was a ship's RO in 1933. During the war he was in charge of radio instruction at the Merchant Marine Academy at Kings Point, NY (where a Mackay console - maybe the one Bob used - was on "display" in a closet the last time I was there). His first transmitter was a classic Hartley oscillator using a 210 while receiving on a regenerative detector using a 201A. Which got out better Bob, the transmitter or the receiver!? After Services Bob joined us at the receive site where he sat at Position 6 and modestly showed his skill on the Blue Racer and sideswiper. There was no way to miss the touch of a true professional. Later, on a tour of the building, Bob spotted two IP501 receivers in a photo of KPH as it looked in the 1920s when the receive site was at Marshall, CA. It's not often that you can ask someone for their opinion of the IP501 based on personal experience in commercial service so I took the opportunity to ask Bob. The verdict: "Great receiver". When the time came to go Bob said the visit had "made his day". It certainly made ours. A tip of the MRHS green eyeshade to Dan and Ron for making the visit possible.
