Right Angle BNC adapters
by John Marranca, Jr 03 Nov '07

Hello my friends, and Happy Saturday: Does anyone know of a source of the MIL-SPEC right angle BNC adapters? I am using a hamfest special, and have a feeling that it's affecting my rx on the birds. No hurry. Just pondering while I am preparing for winter, and making improvements before the snow flies. Thanks!

Re: Simulated Emergency Test via Satellite
by Henk, PA3GUO 03 Nov '07

Hi Bob, Fully agree ! In case of emergency, when we need to forward messages, APRS by the far the most reliable & efficient communication method: - messages take 2 only seconds up/down airtime - spelling family names in voice is error-prone - voice would need voice recording, APRS has findu.com - findu.com can be monitored worldwide (= auto forwarding) See below the message I forwarded during a 17 degrees PCSAT pass.

Quadrifilar Helices
by John Marranca, Jr 03 Nov '07

03 Nov '07

Does anyone know of a website or of construction plans for an 70 cm Quadrifilar Helix antenna? I have heard that they work quite well for an omni-directional LEO antenna. I am looking for an improvement over my Eggbeaters, which have been excellent thus far. Thanks John KB2HSH -- _______________________________ John Marranca, Jr PBX Technician/Shop Steward CWA Local 1122 BN Systems, Inc Orchard Park, NY (716)972-2006

ARISS digi inop?

Haven't had any success getting a packet through the ISS the past few days, even though the beacon says BBS and APRS is on. I know it's been off during the spacewalks, but it's beaconing today, but no packets are making it through. Does anyone have some clarifying information? Tnx, Ken, W7KKE

Hi Jerry, Let me break this down for you a little bit. The only advantage to having an Arrow-type antenna is that you can more easily hold and point the antenna, bypassing the need for a rotor. I wouldn't recommend this method if you're going to use your 857 with out-put of more than 5 watts. The FM birds will require more than 5 watts to get thru all the QRM. If you have two rigs to work with, why not try out AO7, FO29, or VO52? You'll find them easy to get into; I've worked AO7 with my 817, on mode A, using CW and 5 watts into a Ringo Ranger. I couldn't do it on SSB though, AO7 wants a little more gain than that. My antennas now are 11 elements on both 2M and 70cm and I can always hit the birds. I turn them with an HD73 rotor. 73 de N8AU, Jim in Raymore, MO Light travels faster than sound... This is why some people appear bright until you hear them speak.

I swore I"d never do the FM birds cause I don't even do the FM Repeaters. I've lived near Rapid City, SD for 21 years and can count the number of times I've been on the reapeaters here on one hand. Sorry they just don't do anything for me. I've broke down and decieded I want to get on the FM birds. The radio will be mostly my FT-817 or I can go FT-857D if I get the urge. I see antennas like the Arrows where 2 beams are on the same boom, is there a real advantage to this?? My antenna will be mounted outdoors and I'm going in the direction of 2 antennas on a cross boom. I'm not that interested in parading around in a parking lot carring a antenna and looking silly. How much antenna do I really need? I have tried listening on the FT-817's rubber duck antenna with no results. I thru together a hastly built one element egg beater type. (a site to see, held together by duct tape.) The other nite I almost heard AO-51. My next step is tearing off the eggbeater and duct taping a 3 el yagi to the yardstick. I want to see the difference and maybe learn something while playing. I'll go now cause I'm probably wasiting your time thanks for reading this. Jerry - NR5A - South Dakota
