TNX Slon for the quick reply The resistance from pin 6 to 5 and six to 4 is 8.8 ohms and the voltage are the same is 23.4 vac which probably rules out high resistance on the up pin + I check the plug Any other suggestions?? nick Cell 337 258 2527 Helping UL become a world Class Engineering and Educational School Disagree I Learn -----Original Message----- From: Sloan Davis <blkupspilot(a)mac.com> Sent: Tuesday, June 25, 2019 7:42 AM To: Nick Pugh <quadpugh(a)bellsouth.net> Subject: Re: [amsat-bb] Yaesu g5500 rotator issue Check the “plug / din” connection in the wires to the box.

AI6DO Field Day Report
by Ryan Noguchi 25 Jun '19

25 Jun '19

Unlike last year, where I participated in ARRL and AMSAT Field Day concurrently, I did them separately this year. On Saturday, I worked only satellites for AMSAT Field Day from the vicinity of my home. I never operated from my property, only from other operating positions along my block each optimized for specific pass orientations, all well within an 800 ft circle. All QSOs were made fully pedestrian-mobile, without recharging any of the batteries during the Field Day period. Most of the FM satellites were a mess, as expected. The one daylight AO-92 L/v mode pass, 20 degrees to the west, was pretty empty, but gave me my first QSO of the day, with WD9EWK. I chose to dual-wield two antennas rather than attach the two together as I've normally done in the past. I strapped the DJ-G7T radio to the handle of the 10-element 23cm EBay yagi, where the PTT button and the VFO A knob were easily adjustable with just my left thumb; in my right hand, I held the Arrow. This worked pretty well, and I found it less fatiguing than having one heavier antenna. Also made QSOs on PO-101 and AO-85. AO-85 sounded really good, at least for that minute or so I was on. As soon as I got the QSO, I split to go work another pass. Tried LilacSat-2 twice, nothing heard. The SSB satellites seemed to have few operators on, other than QRO CW stations. On one FO-29 pass, there were two CW stations calling CQ nearly on top of each other and on top of a SSB station calling CQ, while most of the passband was empty. Worked several linear passes, but made only one QSO, and we really had to work for that one. The far-western XW-2 passes were pretty empty. The packet satellites were underutilized, and could have been a great source of points had more operators been on. Made several QSOs on FalconSat-3 and PSAT, although only one counts for AMSAT Field Day credit. Unfortunately, the ISS digipeater was offline. Worked a total of 20 passes, although for five of them the satellite was inoperative. Total of 6 qualifying QSOs, half of them with WD9EWK. I had planned to do several more passes that evening and a few more before sunrise the next morning, but I decided to put this day out of its misery and conserve my energy for Sunday. On Sunday morning, I drove to my portable operating location to operate the rest of the Field Day period for only ARRL Field Day. Since I was going to operate 2B1B for ARRL Field Day, I used the same operating category for my AMSAT Field Day contacts for consistency. For the first time, I made a full-time SO2R effort, with one radio dedicated to CW and the other dedicated to FT8. Didn't even try SSB. Also made one FM satellite contact after 1800z from that operating location for the 100 pt bonus and my sole phone contact for ARRL Field Day. So, how'd everyone else's Field Day go? 73, Ryan AI6DO

Correct up-link frequency for PO-101 (Diwata-2)
by Mac A. Cody 25 Jun '19

25 Jun '19

On the AMSAT FM Satellite Frequency Summary it lists the up-link frequency for PO-101 (Diwata-2) as 437.500 MHz. On the PHL Microsat website, the up-link frequency is listed as 437.7 MHz.?? Which is correct??? I tried to work PO-101 during Field Day yesterday and had no success getting in with my radio set to 437.500 MHz, and Doppler-shift adjusted near values.?? Of course, being Field Day, I could have just been 'out-gunned'. I do wonder, though. 73, Mac / AE5PH

2nd/backup FM HT recommendations
by Philip Jenkins 25 Jun '19

25 Jun '19

I'm considering buying another FM HT for the birds, mainly to use as a backup - for demos. (I already have a D72, which is my main unit for personal use and demos right now, and a VX7R, but the latter has seen better days.) For those of you who have attempted to use just a D72 for a demo - with an external speaker as well as the headset/mic - this results in a rat's nest of adapters/connectors/wires. I have the adapter sold on eBay, but unfortunately it attenuates the audio signal (for digital voice recorders), instead of amplifying it for an external speaker , which is what I need. (I guess I could use a powered speaker on that output, but that's one more thing to carry - and power-up! :-) ) So I think *two* radios might work better - wiring wise - for demos. If I buy a Baofeng (or similar), I won't use it for the receive part due to the desense problems on some models (looking at the section in 2019's "Getting Started with Amateur Satellites"). I'm considering the Alinco, since it does have 1.2 Ghz, and using the D72 for receive in that set up (but that still doesn't easily solve the wiring/connector mess for an external speaker/headphones for that radio). Are there other radios which are more "external speaker" friendly which I should consider? I'm open to almost any combination of manufacturers (except for the Baofeng types for receive, as noted above). I'm even open to buying another D72 (but probably hoarding it except for special occasions.) In short, what are your recommendations for a second, spare, radio for the FM birds? I'm also curious how others have wired their single HTs - or two HTs - for demos using an external speaker. So if you could explain - with or without pictures - how you accomplish this, I'd appreciate it. Thanks Philip N4HF

Icom 821h For Sale
by David Swanson 24 Jun '19

24 Jun '19

Hey All, I'm selling my Icom 821h that I've used for the past 4 years to break all sorts of distance records and work all the grids out there. The rig still works amazingly well, and the only reason I'm parting with it is because I upgraded to a 9700, and it's just better. See my listing in the 'Zed forums here: https://forums.qrz.com/index.php?threads/icom-821h-all-mode-vhf-uhf-radio-f… I'd love to see this rig go to another AMSAT member and keep on getting used to work the birds for the rest of time. Email me direct if you're interested. 73! -Dave, KG5CCI
