It is published every week and is made available for unlimited distribution. * SAREX NEWS * ============== The latest in a series of Shuttle Amateur Radio EXperiments (SAREX) can be described as being a success. Although some hardware problems prevented the reception of SSTV and packet radio by the crew of Atlantis, many new milestones were created on this mission. Amateur fast-scan television was successfully received from ground stations by the SAREX equipment on board Atlantis. STS-37 marks the first mission where fast-scan television was ever received on a manned spacecraft. The only other time video images were received in space occurred during the second SAREX mission, carried on STS-51-F in August 1985, when amateur slow-scan television (SSTV) was received on the space shuttle Challenger. SSTV transmissions made by the SAREX equipment carried on STS-37 were successfully received by many ground stations within the footprint of Atlantis. These images, transmitted on 145.550 MHz, showed many details of the extra vehicular activity made by the crew of STS-37. STS-37 also marks the first time in history when a shuttle crew consisted entirely of licensed amateur radio operators. The performance and utility of amateur radio on STS-37, as well as on previous STS missions, help to ensure an opportunity for a permanent and continuing amateur radio presence in space, including the planned space station "Freedom". * NOAA-D NEWS * =============== NOAA-D is scheduled for launch on 14-May-91 at approximately 15:52 UTC. This weather satellite will become known as NOAA-12 after launch and will replace NOAA-10 as the operational morning descending weather spacecraft.

The QSO, made over a long-haul DX path, was accomplished using the Mode K and T transponders flying aboard RS-12. Pat mentioned that he had always hoped someday to make a satellite contact with a ZL station using AO-10 or AO-13 but they were never quite visible to both regions simultaneously. With the advent of continuous Modes K and T operations on RS-12, this may start to become a very popular bird to work DX! Also, with the simplest of equipment requirements, it could become very popular with novice satellite users.

Even a good feedline will consume *some* power due to ohmic losses. Any antenna, matched or not, resonant or not, will radiate *some* power. The key point to understand is that the transformer action of a transmission line with other than 1:1 SWR will cause the transmitter to see an impedance other than the antenna's impedance as a load. This can be good, bad, or indifferent depending on the impedance of the antenna and the length of the line. If the presented impedance is other than 50 ohms, or is reactive, or both as is usually the case, then simply retuning the transmitter to match the presented impedance will give maximum efficiency and no power will be "bottled up" in the transmitter. The absolute value of SWR on the line is unimportant excepting that the higher the absolute value of the SWR the greater the transformation ratio for a given cable length. Operating with a high SWR on the feedline can be an advantage when the antenna is far from 50 ohms or is reactive since the transmission line, acting as a transformer, can transform the load presented to the transmitter to some value within the matching capability of the transmitter's output network. This is very useful for using an antenna over a wide percentage bandwidth such as 80 meters or 10 meters. All antenna matching adjustments can be done at the transmitter rather than up at the antenna feedpoint with no real penalty. Alternatively, if you absolutely *can't* tune your transmitter, and you absolutely *can't* use a matchbox, then climbing up and adjusting your antenna feedpoint to be a precise 50 ohm non-reactive match at some frequency will give you 1:1 SWR and no transformer action. Of course the instant you tune *off* of that magic frequency, the antenna is no longer 50 ohms non-reactive and the SWR is no longer 1:1 and the transformed impedance presented to your transmitter is no longer 50 ohms non-reactive. Your transmitter's efficiency drops off causing your finals to get hot, and YOU NEED TO TUNE YOUR TRANSMITTER. So if you can't achieve a perfect 1:1 SWR, and you can't at other than one particular frequency with real antennas as opposed to a dummy load, then you might as well not worry about SWR at all. Instead, you need to be worrying about tuning your transmitter to match whatever impedance is presented at the end of the line.

He got his no-code license so that he can now do his Physics homework on the air with a buddy, and save a few cents a minute compared with making a phone call.

The event was rated a class M9.8/2F flare, which was associated with radio bursts of a fairly minor intensity. The flare was located at S11E70, within the confines of Region 6593, which is now located at S10E60 as of 00:00 UT on 16 April. This event endured 128 minutes, but was not associated with any sweep frequency events. The flare began at 09:32 UT, peaked at 09:42 UT and ended at 11:41 UT on 15 April. Region 6593 is proving (so far) to be quite active. It has spawned three mid-to-high level minor M-class flares over the past 24 hours and is visibly associated with strong Calcium emissions. Magnetic complexity appears to be quite impressive, although the region is still too near to the limb to discern any great detail. The group has been defined as a beta-delta magnetic group existing in a DKO optical spot configuration. It is of moderately large size and encompasses a total of 25 visible spots (although more spots almost certainly exist). Region 6583 continues as the most prominent and potent region visible on the solar disk. It still sports a beta-gamma-delta magnetic configuration and could easily spawn a major flare anytime, although the recent inactivity in the region may indicate that this group will remain predominantly dormant. Nevertheless, it has the potential for producing a major energetic event. This region has the capability of producing a proton flare. A Potential Satellite Proton Event Warning may be issued within the next 2 to 3 days if this region becomes more active and/or complex. Region 6583 (N08E08) spawned a noteworthy class M3.9/1N flare which began at 19:00 UT, peaked at 19:08 UT and ended at 19:51 UT on 15 April. This event was associated with a moderate to high intensity HF SWF (Short Wave Fade) which was observed over all of North America. The event affected frequencies up to 25 MHz. POTENTIAL TERRESTRIAL IMPACT ASSESSMENT The major class M9.8/2F flare will not produce a terrestrial impact. It will, however, remain capable of producing potentially frequent SID's/SWF's over sunlit areas. This region is also a strong candidate for further major flaring. Geomagnetic activity never increased as was anticipated earlier this week. Conditions are presently quiet and stable. Activity is expected to increase to generally unsettled to active levels on 17 or 18 April due to solar coronal hole effects. Long-range predictions suggest that activity may remain generally unsettled until after 26 April, particularly over the high latitude and polar regions. HF propagation conditions are expected to peak over the next 24 to 48 hours. Some degradation can be expected if the coronal effects increase geomagnetic activity as predicted on 17/18 April. Thereafter, HF propagation conditions will remain near normal or slightly below normal (they are currently above normal for all latitudes). The following Warning is in effect: - POTENTIAL MAJOR SOLAR FLARE WARNING (PROTON FLARE POSSIBLE) No alerts are presently in progress. ** End of Alert ** ------------------------------ Date: 16 Apr 91 12:14:15 GMT From: swrinde!elroy.jpl.nasa.gov!news.larc.nasa.gov!asdsun.larc.nasa.gov!eckman@ucsd.edu Subject: recommendations on Icom handhelds To: info-hams@ucsd.edu I read with interest the review of the new IC-W2A dual-band handheld.
