To those who pointed to various other newsgroups, shame on you! You didn't read the original carefully enough -- note that I used the term "mailing list" and not "newsgroup". These are two separate things. Over here on the MILNET side of the internet, a lot of machines have no USENET feeds for newsgroups, but everyone can get mailing lists (ignoring details like gateway screwups and other mail-black-hole situations...). If those other newsgroups, like sci.electronics, have gatewayed mailing lists associated with them, then they can be useful over here. Do they? If not, referring to them is of no use to a large percentage of readers: those getting Info-Hams Digest.

To: info-hams@ucsd.edu In a recent posting, Joe Skoler asked about 50-75 ohm transformes so he could use CATV line. Here's an answer: You don't need them, even at UHF. All you need to do is the following: Make sure the antenna is really 50 ohms. Then hook up the 75 ohm CATV line (with or without a 50-ohm jumper to the antenna - it doesn't matter). Then route the 75 ohm hardline to its shack destination leaving a few feet extra. Install loosly a connector and check SWR. If it's low enough, then you're OK and you can make the connector permanent. If it's not, then trim off a few inches of the CATV line and try again. Repeat until the SWR is low enough. If you're careful, you can get it to 1:1. The basic principle is that the impedance of the load end of any feedline is repeated at 1/2 wavelength intervals along the feedline no matter what impedance the feedline is. So you just trim the feedline until its input end falls at a 1/2 wave multiple and it will look exactly like the antenna's impedance. In addition, at UHF, the feedline's loss will further improve the picture. In my opinion, this procedure is far less lossy, and certainly simpler, than installing 50-75 ohm 1/4wave transformers at each end of the hardline. I have done it and it works.

George, K8KR, worked a station signing 9G0R on 18087 KHZ on March 29. The operator's name was Jerry and said his QSL manager is LZ1KVZ. As usual WORK FIRST WORRY LATER (WFWL). C30, ANDORRA. FE6BKD reports that he and another French group will be operating from Andorra in May. FE6BKD will sign C30EUA while FE6BKP as C30CAG, FC1LRC as C30EPA and FD1OGG as C30EOA. CE9, SOUTH SHETLAND. Oscar, CE2NVH/CE9, is a frequent check-in on the 14160 Net around 0000Z. QSL to Oscar, Box 74D, Punta Arenas, Chile. Also CE9GEW from South Shetland has been heard on 21225 KHz around 2200Z. CE0, JUAN FERNANDEZ. CE0ZVS has been active on CW on 14006 KHz at 0111Z and also heard around 14025 KHz plus/minus 1 KHz. CE0ZVS also shows up on the 14256 Net around 0000Z. On April 5, CE0ZCD was active on 14205 KHz at 0324Z. QSL CE0ZCD to P.O. Box 1972, Valparaiso 1, Chile. D6, COMOROS. Frank, DL7FT, is now signing D68FT. He is scheduled to be there until April 12 and then leave for Madagascar to try to operate as 5R8FT between April 15 to 25. The following frequencies have been mentioned: CW 14030/18075/21030/24898/28030 and SSB 14190-14195/18125/ 21290-21295/24930/28490-28495. QSL to Frank Turek, W-1000, Berlin 19, Germany. FR/T, TROMELIN. It was reported, on the W2MIG Net, that Yoland will be in Tromelin between May 5 and June 5. Yoland is a meteorologist on a one month work assignment and should be active during his spare time. FW, WALLIS ISLAND. Ron, ZL1AMO, will be traveling to FW-Land starting April 10 to 24 and use the callsign FW0BX. He will operate all bands, CW, SSB AND RTTY. On April 17, VK2BEX will join Ron on the island and stay thru April 24. VK2BEX will sign with a FW0 callsign or FW0/VK2BEX. QSL FW0BX to ZL1AMO and FW0/VK2BEX to BOX 195, Killara, NSW 2071, Australia. S2, BANGLADESH. After over a week of trying to obtain an official S2 license, Jim, VK9NS, is finally signing S21U. That is the good news. Now for the bad news. By the time you read this Jim's S2 operation will be over. Jim operated on SSB for three days starting Wednesday and only during Bangladesh daytime hours (working hours 9 to 5). Word has it he had to operate during the presence of Bangladesh officials. Jim was reported calling VK land on 21255 KHz around 1200Z on Wednesday. Europeans were working him, but the Europeans say Jim had a very very weak signal. I am sure these events are a disappointment to everyone including Jim. We should all thank Jim for all his efforts. MORE S2 INFO. On Monday, the INDEXA Net reported, that Erik ST4/WZ6C will be in S2 on a mission for four years. INDEXA will supply him with equipment as required. Erik will be in S2 on April 27. He has no license yet, but he may be able to activate this one in the near future. SV/A, MOUNT ATHOS. Apollo, SV2ASP/A, sometimes shows upon the 21335 KHZ DX Net on Sundays around 1630Z.

A number of people have asked my opinion of the M-1000, so I thought it better to post a few thoughts on it: Appearance is quite nice, 2/3 length card, seems to be a stable layout without lots of wire jumpers and suchlike. Conveniently fed by just one phono plug. Lacks external scope outputs. Installation and setup is simple. Performs well in my '386 machine. One of it's best points is the excellent EGA/VGA quality fax output. It can store pictures, colorize them, enlarge them...whatever. The pictures are in .PCX format which means you can edit them with the right graphics program. RTTY, CW, packet and a number of other exotic modes are well covered, it lacks the Cyrillic display capability of the M-7000 which is awkward if you like to copy Soviet maritime rtty traffic. This is it's major lack when compared to the M-7000. The software is reasonably easy/intuitive in use, but so far the guy who created this device refuses to release details of the hooks for the card so that third party programmers can roll their own software. In all, it's an excellent unit, somewhat less versatile than the M-7000 but it's excellent FAX display capabilities, print and capture to disk capabilities easily compensate for any shortcomings. Ideally, do what I (an eccentric, wealthy person) do - use the M-1000 AND the M-7000. Between them, they can do almost anything. Give Fred Osterman at Universal Radio a call and talk to him - mention my name (maybe he'll send me a free Universal ballpoint pen....)

The cable company operates very close to the frequencies that have been granted to amateur radio operators. However, both of us use shielding to keep interference from getting into them. If someone is stealing cable then there probably is an open connection and that could cause interference, like the transmission from ham radios, to leak in. What I would suggest is to first call your cable company. Cable piracy is illegal and that may solve most of the problem. Secondly, I would also let the ham operators know that you are hearing their transmission. They may not even know that this is occurring. >I knew >a ham operator personally a long time ago, he actually believed in times of >national emergency, the hams would serve as a functioning communications >network to supercede the phone/microwave/satellite network that would >obviously be destroyed by war or nuclear holocaust. Sorry bud, your stuff >would be just as worthless. Most ham operators have hand-held transceivers, similar to walkie talkies, that are operated by batteries. I know of many situations where ham radio have helped when communication were lost. For example, during the hurricane that hit North Carolina and the Virgin Islands, it was via ham radio that most of the world found out how bad things were. Personally, I think that ham radios would survive a war and even a nucleur holocaust. >So these people spend their time sending postcards >back and forth and seeing how many people they can ask about the weather in >a 24 hour span.

This looks like the best opportunity for wide-open SAREX operations this mission. 73, Gerry Creager N5JXS SAREX Operations 10 Apr 1991 1435 UTC Date: Wed, 10 Apr 1991 11:44:15 CDT From: CREAGER@MEDICS.JSC.NASA.GOV Subject: STS-37 Element Set JSC-011 To: sts-37@n5jxs.jsc.nasa.gov, ckotila@jscprofs.nasa.gov STS-37 1 21224U 91 27 A 91100.71210648 .00023000 00000-0 17236-3 0 112 2 21224 28.4738 203.4571 0012141 343.0095 17.0486 15.37245841 804 Satellite: STS-37 Catalog number: 21224 Epoch time: 91100.71210648 (10 APR 91 17:05:26.000 utc) Element set: 11 Inclination: 28.4738 deg RA of node: 203.4571 deg Space Shuttle Flight STS-37 Eccentricity: .0012141 Keplerian Elements Arg of perigee: 343.0095 deg from NASA Tracking Ephemeris Mean anomaly: 17.0486 deg Mean motion: 15.37245841 rev/day W5RRR Decay rate: 2.30E-04 rev/day^2 NASA Johnson Space Center Epoch rev: 80 [A further note: When I talked to Gerry this evening, he said that they would likely scrub the landing today as well due to generally terrible weather at Edwards...so there's at least one, and possibly two, more days of SAREX.
