NOTE: The Effective Sunspot Number for 07 DEC 93 was 48.0. The Full Kp Indices for 07 DEC 93 are: 3- 1+ 1- 2- 5- 4- 3+ 4- SYNOPSIS OF ACTIVITY -------------------- Solar activity was low. Region 7629 (S21W13) continued to simplify, producing two C-class flares in the process. A 17 degree-long filament disappeared from S39E32 early in the day. A prominence erupted from N13E90 during the latter part of the period. Solar activity forecast: solar activity is expected to be low. The geomagnetic field varied from unsettled to major storm conditions over the past 24 hours. This disturbance is occurring during what had been a recurrent quiet interval over the past five months. It is not clear as to what transitory phenomenon caused the storming. Geophysical activity forecast: the geomagnetic field is expected to be unsettled to active over the next 24 hours, as the disturbance wanes. Strictly unsettled conditions should end the period. STD: Auroral activity was observed into the northern United States over the last 24 hours. Several reports of strong activity were received early in the UTC day, including color variations and rapid pulsations. Activity has since subsided substantially. Conditions are no longer visible over the middle latitudes. Event probabilities 09 dec-11 dec Class M 10/10/10 Class X 01/01/01 Proton 01/01/01 PCAF Green Geomagnetic activity probabilities 09 dec-11 dec A. Middle Latitudes Active 50/30/15 Minor Storm 25/15/05 Major-Severe Storm 05/05/01 B. High Latitudes Active 45/35/30 Minor Storm 35/25/10 Major-Severe Storm 10/05/05 STD: HF propagation conditions were well below-normal over the last 24 hours. Strong geomagnetic and auroral activity produced a particularly strong corresponding ionospheric disturbance over the middle, high, and polar latitude regions. MUFs were depressed by up to 40 percent for high-latitude paths. This, combined with periods of strong fading, multipathing, and auroral absorption, resulted in near-useless propagation for transauroral and many transpolar circuits. Middle latitude paths also saw periods of strong signal degradation, particularly during the local night hours. Conditions began improving fairly rapidly after 18:00 UTC and are now well on the way toward reaching near-normal levels by the end of 09 December for most regions. Australian stations have reported periods of strong continent-wide VHF communications (including TV) on frequencies approaching (and perhaps in a few cases exceeding) 100 MHz, likely attributed to persistent sporadic-E.

The fire department I belong to in going to purchase some new Hi-Lo band radios in the near future and we would like to get a good price. I know this is not a ateur radio request, but I thought someone out there would know a good distributor of Motorola products. BTW I dont know the exact model number of the radios yet. Thanks for any help. P.S. Please send E-mail to this account (This is the account of a friend but I can can use the account to get the replies) osay@sunyit.edu ------------------------------ Date: 11 Dec 93 10:03:39 GMT From: news-mail-gateway@ucsd.edu Subject: Recommendations on HT's To: info-hams@ucsd.edu I'm a brand-spanking new ham, and I'm currently radioless. I've heard or seen good things about the Standard C-168A, Icom IC-W2A, and Motorolas in general. From a (relatively biased, I might add) local ham group, I recieved the general consensus that Alinco HT's aren't worth the boxes they come in. Discussions in this forum have not changed this opinion, although some people have said that they like their Alinco's. I'm not looking for flames here, but simply reviews/recommendations for HT's. I'm a college student (no extra $ here!!!), and I'd like 5W capability. 2m/440 dualband would be nice, but maybe a dream for the $ I'm willing to spend ($200 tops for 2m only, $300 for dualband). If anyone has any suggestions/help/extra radios :-), please email me with them. If I get enough, I'll compile them and post them on the forum for other new hams like me. I'm also looking for a TNC, like a KPC-3 or PK-88. Thanks a lot. 73, Scott Gigot N9VOM segigot@students.wisc.edu Now I have my ticket, but when will the FCC send me my radio? ------------------------------ Date: Wed, 8 Dec 1993 14:41:44 GMT From: news.cerf.net!pagesat!olivea!sgigate.sgi.com!sgiblab!swrinde!cs.utexas.edu!howland.reston.ans.net!sol.ctr.columbia.edu!news.unomaha.edu!cwis.unomaha.edu!rerickso@network.ucsd.edu Subject: RF Ground for 2nd story shack? To: info-hams@ucsd.edu Another way I have heard to do it is to use old RG-8 type coax and run the inner connector to earth ground and a .01 ufd/1000 volt capcitor on each end of the coax going from the shield to inner connector. The shield then is floating. What you want to avoid is grounding any 1/4-wave radials to an earth ground to kill off the RF. You want only one wire or inner conductor to earth ground and at least two or three 8-foot ground rods at least 10-foot apart brazened with hard solder. If you use soft solder or a mechanical connection, in time you could have a resistance induced into your ground connection which is no good at RF and maybe DC return to earth. I would try the coax with capacitors before I would run 1/4-wave radials. I think the MFJ ground tuner might be worth having if you can afford it. 73, Ron AK0N rerickso@cwis.unomaha.edu ------------------------------ Date: Wed, 8 Dec 1993 14:20:35 GMT From: netcomsv!netcom.com!greg@decwrl.dec.com Subject: Scratchi, January, 1960 To: info-hams@ucsd.edu In article <CHp2FM.4s6@srgenprp.sr.hp.com> alanb@sr.hp.com (Alan Bloom) writes: >Faith Senie (fms@sw.stratus.com) wrote: >: I must be missing something.

But sure enough, >there is nothing in the posted article that would give the unitiated a clue. I think there is. The specific pidgin idiom used is one which was commonly used by Americans to mimic Japanese. The important thing to remember (and please get this): The people being offended (Japanese people, Japanese-Americans, and other Asian people) will very quickly recognize the offensive idiom. They have been sensitized to that kind of stereotype and are a deal better at realizing than all the apologists with European surnames who have posted in Scratchi's defense. >(The magazine articles included a drawing of the "author" with obviously >oriental features.) More like an 'oriental caricature.' Again, an offensive idiom because it is the way in which the white race mocked or sterotyped the Asian. >I can understand how the pidgin English might be offensive to some Asians. >It is worth mentioning, though, that I don't ever remember any other type >of racial slur in any of the Scratchi articles. In other words, Scratchi's >personality was not such as to propagate the "evil, devious" stereotype >of Japanese prevalent at the time. That was only one of the stereotypes which operated at that time. Another was the hapless, amusing little man who is always bowing and saying 'honorable.' 'Oriental people are all very polite, and the women are very good housekeepers,' to quote my Grandma. All of these stereotypes are offensive to many Asians. It's a truism that people don't like to be sterotyped, even with supposedly positive characteristics. The clearest example is the old saw about rhythm being "in the blood" of black people. It took many of us a damn long time to get through our heads that that is really offensive. Most of us have learned it, by now. This has been an interesting discussion. It makes it clear to me that there are still a number of so-called intellectuals who understand very little about the politics of prejudice. That many of these addresses seem to come from academic institutions, where there is so much opportunity to learn what it's like from the other side, is truly sad.

I'd be interested in knowing what the fix is. I've heard that some manufacturer fixes reduce radio performance :-( Wasn't there a intermod fix for some brand of HT that simply reduced sensitivity? I would guess the fix in this case won't... Please post the outcome of your dealings with Yaesu; I think the community would be interested. Peter PS: Has anyone ever seen a user-written user guide to the FT530? I come across undocumented how-to's every once in a while. For example, pusing PTT when the unit is off changes the time display to reveal the seconds! Peter A.
