EN84/85 line today
by Paul Stoetzer 28 Dec '16

28 Dec '16

Good morning, I will work the following two passes from the EN84/85 line this afternoon. AO-7 - 2019 UTC SO-50 - 2045 UTC Look for me around 145.940 MHz on AO-7. 73, Paul, N8HM

On this pass it was sending a signal every 5 seconds. I received it with 436.200 MHz USB, but it might be FM. The visible circle of the satellite is very small. Therefore this satellite will decay and burn up in the atmosphere soon. http://www.ne.jp/asahi/hamradio/je9pel/61228by7.jpg http://www.ne.jp/asahi/hamradio/je9pel/by70ca45.htm JE9PEL, Mineo Wakita

BY70-1 launched into too low orbit
by Nico Janssen 28 Dec '16

28 Dec '16

All, Today, 2016-12-28, BY70-1 was launched at 04:23 UTC from Taiyuan launch center with a Long March 2D launch vehicle, together with two GaoJing (SuperView) remote sensing satellites. But unfortunately none of the satellites entered the planned circular orbit at 520 km altitude. All four objects from this launch (41907-41910) are in an low elliptical orbit with a perigee of only around 213 km and an apogee of 524 km. Therefore these objects will decay and burn up in the atmosphere soon. 73, Nico PA0DLO

Re: [amsat-bb] High Altitude Balloon micro battery recommendation
by Ted 27 Dec '16

Skyler, you may want to look at various li-po batteries at your local hobby store. You may find more capacity at the same or close to same weight as watch batteries 73, Ted K7TRK -----Original Message----- From: AMSAT-BB [mailto:[email protected]] On Behalf Of Skyler F Sent: Monday, December 26, 2016 8:21 PM To: amsat-bb(a)amsat.org Subject: [amsat-bb] High Altitude Balloon micro battery reccomendation I am going to send up a few micro beacons (milliwatt HF CW transmitters) probably using Walmart balloons and thin wire as the active antenna/payload string. The CW beacon RF module is a really simple oscillator that drifts a certain amount with temperature - that way I can tell how cold it is based on the received frequency from on the ground. An ATtiny or something similar will probably be used to keep the beacon legal and send out CW every 10 mins to break the carrier. So the whole RF module and beacon is extremely light, basic transistor/crystal oscillator + ID chip so I don't have to worry about recovery. The only consideration is the battery. I will probably have something operational between 3 and 7 volts, so I am thinking about just stringing a few watch batteries together. Is there a certain recommendation for low temperature operation miniature batteries? I need to make this payload as light as possible. The goal is the cheapest Amateur Radio balloon project where recovery is not a worry. Signal strength reports across the country as well as wind predictions can get a good idea of where the balloon travelled. I can then match this data up with the daily National Weather Service launch data to determine how high my balloon went based on temperature. 73 Skyler KD0WHB _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

What file are you using? It shows up in the NASABARE.TXT file. Due to it having been launch as a secondary payload with a classified primary payload, it won't show in most element sets.

AO-85 and SatPC32
by Walter Holmes 27 Dec '16

27 Dec '16

I must be going blind somewhere. :) I have searched up and down through the Keps and can't seem to find AO-85 or Fox1 in there anywhere. And because of that, I can't find that in SatPC32 of course. Is there some other name that it shows up as in the keps file that I have missed somewhere? Many thanks, Walter/K5WH

Another Balloon - what frequency?
by Scott 26 Dec '16

26 Dec '16

Hope everyone had a nice Christmas. I see that there is another balloon headed my way: https://tracker.habhub.org/#!mt=roadmap&mz=6&qm=1_day&mc=37.13154,281.71854… ... and on the side legend it indicates "Received 1h 56m ago via: APRS, W4DEX". I have searched but cannot find what frequency this thing might be on. Since APRS is indicated, that would be 144.39 in this part of the world but it could also be using something like 145.825 and be picked up by iGates configured to receive the previously-used ISS packet traffic on VHF. I'm usually fairly decent at finding things on Google, but no luck so far with this. Would anyone more familiar with balloon tracking possibly point me in the right direction? Thanks! -Scott, K4KDR Montpelier, VA USA twitter: scott23192
