Possible trouble with new Icom IC-910H
by Peter Pauly 12 Aug '17

12 Aug '17

I bought a used IC-910H on ebay for satellite work an am having a possible issue with it. I tested the 2m and 70cm transmitter and receiver in FM mode with my handheld and they work fine. I hooked up a Bird 43 wattmeter with a 50E slug (50W, 400-1000Mhz) and when I transmit on 440Mhz FM I get an indication of power output on the meter. So far so good... Then in USB/LSB mode however, I get no indication on the meter, despite turning the mic gain up and talking into the mic. I've also up'ed the RF power with the little knob and that doesn't help. The red light flashes on the rig (ALC indication) and the meter on the rig moves. I can also hear distorted audio on my FM handheld (as expected since it's FM and not USB) but I'm worried about the lack of power indicated on the Bird. I haven't been able to try CW yet because I don't have the right sized plug. Should I be concerned about the lack of power? Summary: Bird wattmeter shows power out on FM, but not on USB/LSB. Thanks Peter W9KG

W5PFG/P Northern Maine Grid Expedition II
by Clayton Coleman 12 Aug '17

12 Aug '17

I will depart for a satellite grid expedtion to northern Maine on Friday, August 18. The trip will conclude the morning of August 21. I'll roughly follow the same path I used on a similar expedition January 2015. Planned grids will be: FN54-57 and FN64-67 Due to the short duration of this trip, my satellite pass selection will be dynamic. I will probably not work many passes from each unique grid. I'll do my best to work from grid boundaries on passes with wide coverage. Monitor my Twitter feed @w5pfg for updates during the trip. 73 Clayton W5PFG

KG5CCI Roving 8/12/2017 thru 8/22/2017
by David Swanson 11 Aug '17

11 Aug '17

Got some travel plans coming up the next few weeks, and people have expressed interest, so here's the details: 8/12/2017 I'll be traveling to EM43 to operate some Meteor Scatter on 6m for the Perseids, but will also operate Satellites from EM43 while there.. afterwards I plan on scooting down to EM42 and EM41 to do some more Sat passes before heading back to EM34 via whatever path I happen to feel like. 8/16 - 8/17 I'll be traveling from EM34 to EM38 on some business, but should have time on the way up and back to do some passes. Watch twitter closely, cause these will likely be little warning activation. 8/20 - 8/22 I'll be traveling from EM34 to EN21 for the Eclipse. As with most eclipse chasers there's a very real possibility I may have to drive from EN21 to wherever it's clear on the 21st... so there's a chance I might end up out in Western Nebraska. Once again, watch twitter, cause who knows where I'll end up. On the 22nd I'll be heading back to EM34 from wherever my final Eclipse destination takes me. Good luck! 73, Dave, KG5CCI

Re: [amsat-bb] [aprssig] What satellite is this ?
by Robert Bruninga 11 Aug '17

Scott, What kind of digipeater is it? We need to know how to parse the digi path to pull it out as a satellite digipeated packet. What aliases does it support? Only YOBX-1 as a path? or does it also support APRSAT and ARISS? Does it do callsign substitution or insertion? IE, when it digipeates on an alias does it do substitution like this: YBOX-1*, Or does it do substitution like this: YBOX-1,APRSAT*? Then Steve can add a parser for it to show up on pcsat.findu.com Bob *From:* aprssig [mailto:aprssig-bounces@tapr.org] *On Behalf Of *Scott Miller *Sent:* Thursday, August 10, 2017 7:01 PM *To:* aprssig(a)tapr.org *Subject:* Re: [aprssig] What satellite is this ?

Mayak ‘Lighthouse in the Sky’ Fails to Deploy Solar Reflector – Soyuz – 73 Satellites
by John Brier 10 Aug '17

10 Aug '17

Double fail: "Per Mayak’s simple design, the project engineers did not include a radio as the satellite could be programmed on the ground to autonomously execute its critical tasks in orbit to complete the deployment of the solar reflector. Later in the design stages it was realized that a radio would be beneficial, however, no radio channel could be allocated to the satellite this close to launch. A backup plan of using a series of LEDs on the satellite to deliver basic telemetry in the form of a visual Morse Code never came to fruition, leaving Mayak without any means of communicating its status to the ground." Also, LEDs? I guess there are telescopes that could see it and track it. http://spaceflight101.com/soyuz-kanopus-v-ik/mayak-lighthouse-in-the-sky-fa…

If your rig can do it center on 435.172. If not use 435.170 as your center frequency. Be sure to use a 67.0 hz pl in either case. I know nothing about AO 73, sorry. 73 John KI4RO <https://mailtrack.io/> Sent with Mailtrack <https://mailtrack.io/install?source=signature&lang=en&referral=johnki4ro@gm…>
