AO-92 L Band Power
by Alan Blind 09 Jul '20

09 Jul '20

Using 10 Watts, I have not been able to get into AO-92 L Band. >From the AO-92 web site: ================ ......Since the 435 MHz uplink antenna is used to receive the 1267 MHz signals and may present a mismatch at that frequency, pre-launch estimates suggest that a power level of 100 watts ERP will be required for horizon-to-horizon access in Mode L/v. AMSAT Engineering will issue further guidance after in-orbit testing. Look for future articles on the AMSAT website and in The AMSAT Journal for equipment ideas and tutorials for accessing the L-band uplink. ==================== Perhaps my 10 Watts are too low. Have there been updates from AMSAT on recommended L band power? What power do others run? Alan WA9WUD

AO92 pass, 0510z 7/9
by Russ Kinner 09 Jul '20

I worked a station operating in Teton N.P. (DN43) on the pass Sat night and thought I had the call but even after listening to the recording I'm not sure. The call was in the fade when sent phonetically. Several other stations also worked him so if you heard KC5FLQ or KC5SLQ or his right call, can you advise? It's a new grid for me. Rusty, WA8ZID

Congratulations to Kevin, N4UFO, for earning AMSAT GridMaster Award #12. -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 -------------------------------------------------------------------------- Thanks, Bruce! Took me just over 5 years to complete that... got back on sats in spring of 2013 and worked the last of the 488 in the summer of 2018. (Thanks N7AGF!) Hopefully I will be able to get back on the sats sometime in the future and pass it along by giving out some grids again. I appreciate you doing all the work to process that, I look forward to seeing something in the mail soon. =^) - 73, Kevin N4UFO

Re: [amsat-bb] G5500 control unit switch
by Gregory Beat 08 Jul '20

Bob - This is an OLD Topic, that Yaesu Repair Parts in USA, NEVER adequately addressed. Yaesu purchased the Kenpro rotator product line over 25 years ago. The original supplier (OEM) for Front Lever Switch to Kenpro, discontinued the part. — There are other rocker switches (of proper size) that will fit the Kenpro/Yaesu front panel mounting holes. HOWEVER, the original switch mfg. used an OFFSET Lever (Pivot) that was NOY Symmetrical about the pivot axis. Kenpro designed ALL of their front panel molds (rotator controls) to work with that Offset Lever style. Photos of one of the LAST Switches (discontinued) that Yaesu USA had left 6 years ago. Photos at entry #8 (QRZ Q&A Tech Forums). https://forums.qrz.com/index.php?threads/g-500a-replacement-switch.664784/ The Yaesu Solution SHOULD BE to offer that common NKK switch, and then have a Custom Lever molded for compatibility with the front panels. In 2014, I identified and purchased a NKK rocker switch (NKK Series M2) from Mouser, NKK # M2022TYW01 (Cost $4.80 back in 2014). https://www.mouser.com/ProductDetail/633-M2022TYW01 This rocker switch fit properly on Kenpro/Yaesu front panels (rotator control). https://www.mouser.com/datasheet/2/295/MrockersFlatFrame-1663268.pdf HOWEVER, the standard NKK Levers (Paddles) do NOT work — Pivot NOT OFFSET. NKK # AT4157C (Red color) https://www.mouser.com/ProductDetail/633-AT4157C Datasheet https://www.mouser.com/datasheet/2/295/accessorieshardware-10910.pdf SO, All you need is the Proper “Off Set” Lever. This could be 3D-Printed OR Injected Molded (Plastic) from a CAD design. GOOD LUCK ! greg w9gb == Date: Tue, 7 Jul 2020 20:51:58 -0700 (PDT) From: 73 Bob W7LRD <w7lrd(a)comcast.net> To: amsat-bb <amsat-bb(a)amsat.org> Subject: [amsat-bb] G5500 control unit switch Hello I am going through some %$#$@ drama with Yaesu in trying to get a simple switch with paddle for my G5500 control unit. They sent me a couple of switches the paddles do not come with the switch. The switch and paddle have been removed but the paddles I have on backorder (still on boat) if the are the same as I have are incompatible with the switches they sent. The plot thickens. I believe out there somewhere there is G5500 control unit that is destroyed for whatever reason and I could cannibalize the switch. This drama with Yaesu has turned into a pita. This is a potential high failure item and should be easily available. Help needed. 73 Bob W7LRD

AMSAT-NA Malfeasance?
by Clint Bradford 08 Jul '20

08 Jul '20

People throwing out large dollar amounts ... claiming mystery and underhandedness ... I see all this as an $803.50 issue. Take those fees paid by duly-appointed AMSAT-NA officials, less the forgivable $17K CARES grant, and the true outlay is only $803.50. Unrelated categories? Sure. But sure looks like AMSAT-NA is takin' care of business. The only current candidate who has shown total respect for amateur radio and is dedicated to making it more enjoyable for all is Bruce Paige, KK5DO.
