[lots deleted] >ARRL June VHF Contest 2/Jun 33 Looks like either CQ misprinted this or someone somewhere made an assumption that the ARRL June VHF QSO Party is on its traditional second weekend of June date. As it stands now, the ARRL June VHF QSO Party is on the FIRST weekend of June in 1994. I've already written letters to several ARRL people to complain about the date change. Dave Sumner at ARRL HQ replied to tell me he is passing it off to the ARRL Membership Services Department. I don't think there's much chance of the date being moved back to its traditional second weekend of June. 73, Scott WO1G sasminkey@eng.xyplex.com ------------------------------ Date: Sun, 20 Mar 1994 12:52:55 MST From: ihnp4.ucsd.edu!usc!math.ohio-state.edu!cyber2.cyberstore.ca!nntp.cs.ubc.ca!alberta!ve6mgs!usenet@network.ucsd.edu Subject: Daily Summary of Solar Geophysical Activity for 19 March To: info-hams@ucsd.edu /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ DAILY SUMMARY OF SOLAR GEOPHYSICAL ACTIVITY 19 MARCH, 1994 /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ (Based In-Part On SESC Observational Data) SOLAR AND GEOPHYSICAL ACTIVITY INDICES FOR 19 MARCH, 1994 --------------------------------------------------------- NOTE: Minor stratospheric warming exists over eastern Siberia, Alaska, Canada, the Canadian Arctic, Greenland, and southern Europe.

Just one simple spot group, 7692 (N19E19), remains. The northernmost 8 degrees of the large diagonally-oriented filament in the western hemisphere disappeared during the first part of the day. A prominence located near N21E90 was seen to erupt at 0633Z. Solar activity forecast: solar activity is expected to persist at very low levels. The geomagnetic field has been at quiet to active levels for the past 24 hours. Nighttime substorms have weakened. The greater than 2 MeV electron event is declining, with peak values of near 1.0E+04 observed during the day. Geophysical activity forecast: the geomagnetic field is expected to be predominantly unsettled the first half of the forecast period. A favorably positioned coronal hole should send high speed solar wind this way the latter part of the interval. Active to minor storm conditions are anticipated then.

The FCC considers their processing time to be 90 days--from the date they receive the application. The FCC usually receives the application one to two weeks after the test session (once the VE Team and the coordinating VEC have completed their processing). Note: Codeless Technician to Technician w/HF upgraders (who pass a Morse code test) will not receive a new license from the FCC. The existing Technician license plus the CSCE conveying the Morse code test credit is the only documentation issued for use of the additional HF privileges. ***************************************************************** The following test session information is provided by the ARRL/VEC for the upcoming six to eight week period. For further information, please contact the test session CONTACT PERSON at the telephone number provided. If necessary, you may contact the ARRL/VEC at 203-666-1541 x282 for additional information.

To: info-hams@ucsd.edu I know I could go and buy a diplexer ( to drive a VHF and a UHF antenna from the single output of my dual bander) but they seem very expensive for what should only be a couple of coils and a couple of capacitors (OK a few of each). I have checked all my antenna and radio books, and all those I can find in the library, but none of them even mentions diplexers. Can someone please point me towards or provide design details, or a circuit description, or ANYTHING. Maybe even a different (i.e.correct) name so I can find them in the index. I don't believe there is nothing written about them. Incidentally, I am UK based, so UK magazines (i.e. RadCom or PW) would do...
