The slight system losses, if any, caused here would certainly be offset by the rather low loss characteristic of this big line. In general, the theoretical VSWR in a 75/52 mismatch would roughly be just that - 75/52 = 1.4. Of course, there are a number of factors here. The odds are greater than 50/50 that you would get great results without any special transformers. Have that Bird wattmeter handy and just go for it. If there are problems, then worry about it. I routinely use foam RG6 and F-connectors/adapters wherever most people would use (awful) RG58. Measurements with the Bird wattmeter or the IFR have confirmed no real problems with this. In the ultimate heresy, I even connected up my Radio Shack CB transceiver with F-connectors and RG6; no problem. Similarly, my Icom U400 radio didn't mind it a bit at UHF for 20' (I prefer super low loss 9913 for longer runs). In the (very unlikely) event that you need transformers here, you would probably want to make the "coaxial" type from instructions in antenna books or occasional Ham Radio articles, etc.. -- KUFX | w ["] | WA6MBV 94.5 |.. |___|_____..duncan@bolero.ati.com | Jim Duncan FM | H | +1 408 297 5977 \_____I_____/ 37 3 10N/121 59 10W --------------- ------------------------------ Date: 14 Apr 91 23:57:09 GMT From: swrinde!cs.utexas.edu!asuvax!ukma!usenet.ins.cwru.edu!tut.cis.ohio-state.edu!n8emr!gws@ucsd.edu Subject: am To: info-hams@ucsd.edu ============================================================== | Relayed from AMSAT BBS NETWORK | | N8EMR's Ham BBS, 614-895-2553 | ============================================================== SB ALL @ AMSAT $ANS-104.01 AO-16 BBS TEMPORARILY OFF HR AMSAT NEWS SERVICE BULLETIN 104.01 FROM AMSAT HQ SILVER SPRING, MD APRIL 14, 1991 TO ALL RADIO AMATEURS BT Filled Memory Buffers Cause Temporary Outage of AO-16/LO-19 Bulletin Boards This week the AO-16 file server software, known as FTL0, encountered an anomaly which caused the AMSAT Software Engineers "scratch their heads" for awhile trying to figure out what had happend. It appears that a software bug in the file server caused many memory buffers to fill up but not be allowed to release when they were finished being used. Memory buffers are quite common in BBS and packet TNC software because they hold the packets until they are ready to be sent to the proper memory location or until transmitted. Thus, when uploading or downling a file, the contents always pass through numerous buffers both in the orbiting software and in ground station equipment. NK6K feels that it took a very special set of circumstances for this problem to manifest itself. One of the conditions was heavy usage of the BBS. NK6K has completed work on a "patch" which has fixed the problem, which should not be a concern in the future. It is believed that this is the same problem which caused LO-19 to crash about ten days ago. Both AO-16 and LO-19 will have their file server software "patched." The advantage of "patch" procedure is that no files will be lost on the spacecraft and a complete reload of the BBS software will not be necessary. It is the opinion of the Software Engineers that this sort of problem will eventually disappear and users will be left with a stable and problem-free file server system. /EX SB ALL @ AMSAT $ANS-104.02 SAREX FSATV OPERATION HR AMSAT NEWS SERVICE BULLETIN 104.02 FROM AMSAT HQ SILVER SPRING, MD APRIL 14, 1991 TO ALL RADIO AMATEURS BT Successful Fast Scan Amateur TV Reception by STS-37 Ken Cameron, KB5AWP, Pilot on the Space Shuttle Atlantis, reported good FSATV reception from the selected ground stations on at least four orbits of the STS-37 space shuttle Atlantis mission. Typically, his reports were been brief because his talk back on 2 meters caused some interference to the video. He also asked for FSATV transmissions which he recorded on a VCR in the shuttle while he was too busy with other duties to be in attendance. Picture quality was reported as P4 or better. Most pictures were black-and-white, but some color reception was reported. This is the first Full Motion Video signal ever received by any orbiting manned spacecraft. In a past SAREX Mission, STS-51F, (which carried Tony England, W0ORE) Slow Scan TV was uplinked from ground based stations. The FSATV experiment is being looked at by NASA as an inexpensive mechanism to transmit detailed imaging information to the astronauts while in orbit Only a handfull of stations were chosen to attempt the FSATV experiment with STS-37. An STA from the FCC was required because the wide bandwidth required for FSATV (6 MHz) could not be completely contained in the 435 - 438 MHz Satellite sub-band of 70 cm Amateur band. The succesful uplinking stations were using moonbounce or near-moonbounce class transmissions, several hundred watts of power to antenna arrays of much higher gain than a typical OSCAR station. AMSAT congratulates KC6A, WA4NZD and N9AB for their success with this Shuttle "First". Also participating in the experiment was W5RRR, WB4APR and KE4PT. However, due to unfavorable orbiter attitudes during their designated transmission periods, they were unsuccessful in having their signal received by STS-37.

I suppose that if you wanted time to the nearest second or tenth, its probably OK, but don't bother with the RS-232 interface. For a WWV synchronized clock, it really does a crummy job for semi-serious timekeeping. There plenty of room for improvment in the RF section as well as the RS-232 interface. Its adaquate for sticking on the shelf and looking at it for the current time, but don't get too excited about using it for precision time. louie WA3YMH ------------------------------ Date: 14 Apr 91 13:39:00 GMT From: news-mail-gateway@ucsd.edu Subject: Info-Hams Digest V91 #286 To: info-hams@ucsd.edu UNSUB INFO-HAMS ------------------------------ Date: 14 Apr 91 12:01:04 GMT From: nitrex!rbl@uunet.uu.net Subject: large 110->220 transformers To: info-hams@ucsd.edu In article dh1s+@andrew.cmu.edu (Donn Hoffman) writes: |>I am moving to Spain and want to bring several appliances (eg: |>macintosh, fax, blender, stereo). |> |>Power in Spain is 220v/50hz.

Macs use switching power supplies which run on anything up to 240v. Just get the appropriate physical adapters for the line cord plug to fit into the wall socket outlets. Depending upon your clock radio ... it may or may not lose time on 50Hz. Mechanical ones will, almost certainly (10 minutes/hour). Some digital ones may, depending upon the label on the back/bottom of the clock radio.

Some fairly good shear also exists in this region, which has resulted in several M-class flares over the last couple of days. This region (located at N09E34) is now moderately large, and contains 57 spots in an EKI optical configuration. This region could spawn a major class M or X flare anytime now. It could also produce frequent low level M-class flares. Potential proton activity from this region is not yet a great threat, although the risk is increasing daily should a major proton flare erupt from this region. Region 6580 (N29W10) has also developed a clear delta configuration in its spot complex, and is also exhibiting growth and increased complexity. This region is capable of spawning low-level M-class flares and may become capable of producing more intense major activity soon, if growth continues. Region 6555 (the major activity center responsible for seven large X-class flares and the major geomagnetic storm of 24-26 March) is showing signs of returning back into view on the east limb. Surging was observed on the southeast limb near 12 degrees south solar latitude. Extensive plage is also visible in that vicinity. An optically uncorrelated class M3.1 x-ray burst was observed beginning at 08:41 UT, peaking at 08:52 UT and ending at 10:07 UT. This long-duration event could have been produced by returning Region 6555 (which will be given a new number shortly). We should know within the next 48 hours whether this region has decayed significantly or not since it disappeared from view around the west limb on 31 March. Watch for possible major flare alerts. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ ------------------------------ Date: 15 Apr 91 04:23:42 GMT From: usc!samsung!munnari.oz.au!manuel!ccadfa!sserve!news@ucsd.edu Subject: Shuttle Packet No-Show To: info-hams@ucsd.edu ------------------------------ Date: (null) From: (null) For the interest of the net, one amateur here in the Australian Capital Territory, VK1DF, received a beacon packet from STS37 on the first day of the mission.
