It was close - but the giant fly seen at T MINUS FIVE SECONDS did not interrupt today's spectacular space mission. http://bit.ly/dx9Vot Clint, K6LCS

mmsstv usb ptt under wine
by Phil 05 Jun '10

05 Jun '10

Thank you for reading this. Not long ago I remember reading, on this list, about someone running mmsstv under wine. I've had receive only capability for sometime but after recently receiving good sstv from Seeds my interest in transmitting sstv has been reawakened. I have the extfsk dll installed in the same directory as mmsstv and its dialogue box opens to show that the ptt is on during transmit, however, the transmitter is not keyed. The port option in mmsstv is set to extfsk. The extfsk dialogue box has a status indicator the reads "Status:NG". This possibly means "no good". The status reads the same under Windows, so the problem may not be specific to Linux and wine. By the way, the rts line does key the transmitter while using native linux applications. -- Regards, Phil

WD9EWK - Saturday @ Show Low AZ hamfest & DM54
by Patrick STODDARD (WD9EWK/VA7EWK) 05 Jun '10

05 Jun '10

Hi! After a 3-hour drive from Phoenix, I am in eastern Arizona in advance of the White Mountain Hamfest in Show Low, Arizona. I will have an AMSAT table at the hamfest tomorrow morning, and demonstrations planned for several passes: 1338-1349 UTC on FO-29 SSB (maybe) 1349-1411 UTC on AO-7 SSB 1542-1602 UTC on AO-7 SSB 1613-1626 UTC on VO-52 SSB 1714-1730 UTC on HO-68 SSB 1730-1744 UTC on SO-50 FM 1750-1801 UTC on VO-52 SSB (maybe) 1913-1924 UTC on SO-50 FM 1937-1944 UTC on AO-27 FM The hamfest site is in grid DM44xg, and officially runs until 2000 UTC. I hope to hear K8YSE and KD8CAO at their hamfest in Michigan along with N2SPI at the Rochester NY hamfest and KK5W operated by N5AFV in Texas. Lots of activity tomorrow morning. After the hamfest, I will find someplace in DM54 for passes in the afternoon and evening. I have already tried to find a spot on the DM44/DM54 grid boundary. Trees and "No Parking" signs have ruled out some places I've already surveyed this evening. I found a spot north of Show Low that might work. I may be able to get on the AO-27 pass at 2118-2125 UTC from DM54 or possibly DM44/DM54. After that, I plan on attempting the following passes from somewhere in DM54 or on the DM44/DM54 boundary: 2256-2311 UTC on AO-7 SSB 2315-2329 UTC on AO-51 FM I have 3 passes that overlap in the 0040-0110 UTC period: 0043-0105 UTC on AO-7 SSB 0053-0107 UTC on FO-29 SSB 0054-0108 UTC on AO-51 FM I am leaning to working one of the SSB passes, probably AO-7 since it is the longest of the 3 passes. I might work the first part of the AO-7 pass, and then switch to AO-51 for the west-coast operators that may be looking for DM54. Please e-mail me if you are in the western US or Canada, and would like to try for a QSO on that AO-51 pass. After that, SO-50 comes by at 0206-0219 UTC. Then FO-29 and AO-7 pass by around 0237-0257 UTC. I'll probably start on AO-7, if I am still outside working the radio at that hour (approaching 2000 local). I don't want to stay out too late tomorrow night, since Sunday morning will start very early, for the 3-hour drive up to DM56 in time for mid-morning passes. As with my other road trips and hamfest demonstrations, I will be happy to QSL all contacts made with WD9EWK from the hamfest and wherever I end up in DM54 tomorrow. Just e-mail me with the QSO details; if you're in the log, I'll send out a card. 73! Patrick WD9EWK/VA7EWK - Pinetop-Lakeside, Arizona http://www.wd9ewk.net/

Re: Helix Reflector
by WILLIAMS MICHAEL 05 Jun '10

Ed - KL7UW, WD2XSH/45 said: "You might be interested in the Helical Beam that Mike Cook designed in 1996 for reception of the Mars Global Surveyor (MGS). He used a 10.66 inch diameter loop Reflector. " I have built two 70 cm helix antennas using the loop reflector. The first one was an exact copy of AF9Y's at 11 turns. My first helix build. The second is an 18 turn also with the loop reflector but uses aluminum wire for the helix and the 10.66 in. loop reflector is 1/4 inch copper tubing. I'm going to remove it soon and change to a screen reflector to try out Claire's (VE3NPC) matching system. I'm working up an article on helix building and what I've been able to put together is that the reflector can be .6 to 1.1 wavelength. The ARRL Satellite Experimenters Handbook specifies .6 wavelength in their chart. GL Mike (K9QHO)
