Re: [AMRadio] AM IARU Region 2 Bandplan
Band plan sand plan - thank God they are plans not rules. Talk where you want according to the actual rules. The problem is that once the bandplan is adopted, essentially a treaty, the FCC would eventually need to modify the rules to align with it. I'm not sure if the League is so much on a quest to eliminate AM as continuing it's lemming like plodding lowest common denominator thinking which has lead our hobby to the sad state it's in today.

Re: [AMRadio] QRM fron Neighbor's Security System
It can be quite interesting approaching someone who innocently is a source of interference. Years ago when I worked in two-way we had a problem with interference on the input of a customers repeater. A signal would come and go, sounded like TV raster. Was strong enough to take out the lower power mobiles, which generally were about 15 miles from the repeater. We started hunting it from the repeater site. Ended up in a nearby town, then into a neighborhood. By then it was so strong that we had trouble isolating one house. Noticed a UHF dish on one tower. I said to my boss I bet someone who's that interested has a preamp up there. We were right. He pulled the power to the preamp, and the signal went away. But we had to do come explaining how his TV was interfering with security guys twenty five miles away. Luckily we took a receiver into his house, could hear the interference, and that it went away when he killed the preamp. Even still, I'd rather approach the person than ever call the Commission. After having my radio station inspected twice, I'd rather keep my distance. And then there's the story of a guy I knew who complained to the Commission about a competitor and ended up being given a LONG list of violations himself.

Re: [AMRadio] Hot Broadcast Towers
Even the induced RF can be very unconfortable. When we rebuilt my former four tower array, I had a welder up one of the towers (Tower 2,, Steve) welding one leg together. That tower wasn't being fed, and was grounded. But every now and then a carib eener the welder had on his harness was touching the tower and his arm. The induced RF was nailing him. When he came down his arm had little burn marks all over it. They waited until I got to the site that morning to ask if I could lower power even more. Which I did. Then I asked why they didn't call me earlier, he said I didn't want to be a problem. Geez. Robert A. Poff Loganville, PA.

[AMRadio] Anti-AM Opinionated Hams
I think most of the anti-AM attitude is just the lowest common denominator speaking. To them Slop-bucket is the standard voice mode on HF. So it follows that anything else is evil. Some years ago I had a discussion with one of the locals who exhibits this thinking. His reasoning (like most of them) was that AM occupies too much bandwidth. And of course we need to conserve spectrum. So AM should be outlawed. I countered by saying that on 2 meter CB there's not enough room for all the FM repeaters. Since ACSB occupies such little bandwidth you could put at least four repeaters of that mode in the same spectrum of one NBFM signal. So they should out outlaw FM on 2 meters and everyone switch to ACSB. (tongue firmly implanted in cheek) His eloquent, well thought out response? But EVERYONE uses FM! Robert A.

[AMRadio] Fw: {Collins} Special event operation THIS WEEK from Rockwell Collins - AUGUST 29
This from the Collins List:
- Original Message -
Sent: Monday, August 27, 2007 6:57 PM
Subject: {Collins} Special event operation THIS WEEK from Rockwell Collins -
AUGUST 29
List members:
I, along with the other members of the Collins ARC here in Cedar Rapids,
just learned this afternoon that there will be a SPECIAL OPERATING EVENT
from Cedar Rapids, Iowa, this WEDNESDAY, August 29th. The event is as
follows:
Many of you probably have heard in the news that the US Air Force is
shopping for new air refueling tankers to replace the aging KC-135
fleet. There are competing bids for this proposal from both Boeing and
EADS (Airbus). Rockwell Collins is part of the Boeing Team, and this
Wednesday, Boeing is bringing a special exhibit van to Rockwell Collins in
Cedar Rapids that will provide employees with a view of the proposed
aircraft. In conjunction with that exhibit, the Collins ARC has been
asked to set up the B-29 radio equipment to illustrate the fact that
Collins equipment has been on the Air Force Tanker from the very
beginning. The first tanker was adapted from the B-29 and called the
KB-29. It carried the same radio gear.
The Boeing van with displays of the new tanker, which is based on the
767, will be set up in front of one of the major buildings. Next to the
van will be a tent. CARC will be in the tent on a 6-foot table. I'm
having signs made, etc. The icing on the cake will be if we can get the
ART-13 and BC-348 operating and on the air. To this end, people are
rounding up the necessary items to put up a wire antenna to a nearby tree.
We are working on power sources.
Here are the frequencies proposed for use (these according to general band
plan/agreements):
80m AM: 3885 kHz (and perhaps 3880, as well)
80m CW: 3710 kHz
40m AM: 7290 kHz
40m CW: 7110 kHz
20m AM: 14,286 kHz
20m CW: 14,060 kHz
ESTIMATED OPERATING TIME: The latest information I received (just prior
to writing this message) is to expect on-air operations to START in the
vicinity of 10:30 to 11:00 AM, CDST, which is 1530 to 1600 UTC. It is
anticipated that the on-air opertations will continue for several hours.
Although this hasn't been stated as yet, I expect that the call used will
be W0CXX, Art Collins' call.
There will be an attempt to coordinate information to the CCA Reflector as
events develop on Wednesday. Alas, we do have rain in Wednesday's
forecast, but it is not presently predicted to be an all-day situation.
Some of you may recall the first attempt to get the B-29 equipment up and
running. That was about two years ago, and the equipment was set up in
the Cedar Rapids History Center, located in downtown Cedar Rapids. The
main problem was that local electrical noise levels were so high that the
ops at the station could not copy stations that were 20 over 9. I was
operating from my home QTH that day, relaying information to the que of
folks waiting to make contacts with my mighty DX-40! Hopefully, this
time will be much more successful.
I, and perhaps other CARC members, plan to be on the CCA Tuesday night net
tomorrow night, 0100 UTC, at 3805. If there is additional information,
we'll pass it along at that time. So, gang, warm up the heavy iron and
prepare for some fun. Yes, we know this is short notice and we know this
is a weekday operation, but this is quite an opportunity to show the vast
time spread of Collins radio equipment contributions to the Air Force and
related communications.

SpaceShip One isn't unique. It's AM because the blocking effect that FM exhibits is considered unacceptable. With AM, if two stations interfere you can usually hear both signals to some degree through the heterodyne. With FM, one station would block the other. The flight safety boffins wouldn't like that. SSB of course would be too labor-intensive for aviation service. regards, Mahlon - K4OQ
