[amsat-bb] Re: APRS Twitter
Hi Rizwan, First of all: we are all very interested in your CAPE-2 project. Would you be able to share some more information on CAPE-2 ? In case you involve radio-amateurs in capturing telemetry/data from your satellite you will have an huge increase in coverage, as we are spread across the entire globe. We do have the APRS system up-and-running, and NO-44 (PCSAT-1) and ISS-APRS data packets for example are monitored and automatically forwarded to the internet already. On messaging to twitter email: In case of a malfunction or wrong software setting the satellite may not be able to change its transmission pattern, when it is in space and cannot be reached anymore (e.g. up-link broken). Alternative would be to break it up in two steps: Step 1 Transmit a status in APRS format, and have that captured/received as regular packets. Here is for example how all the ISS data (real-time) looks like: http://www.ariss.net, and here is how NO-44 looks like: http://www.findu.com/cgi-bin/pcsat.cgi Step 2 Have a software program running that looks at the the received APRS telemetry, and derive from that a Twitter tweet (every hour, every day, ...). For example if the telemetry says: CAPE 012000105 this could mean I am alive and battery voltage is 10.5 volt and temperature is 12 degrees Celsius. The tweet could be: Hi this is CAPE-2 in space, I feel cold (12C) and my battery is good (10.5V). Just a thought. Regarding APRS email: http://www.aprs.org/aprs-messaging.html explains how to do this.

Hi Henk, CAPE-2 is the second satellite from the Cajun Advanced Picosatellite Experiment. We are planning to fly a digipeater, text to speech module, voice repeater and VHF and UHF radios. I am currently developing software to distribute to you guys later this year that will copy our telemetry and have it automatically sent back to us. We have already implemented the ability to send APRS emails, but would now like to do the same with twitter.

[amsat-bb] Re: APRS Twitter
CAPE-2 ... [is] planning to fly a digipeater... I am currently developing software to distribute to you guys later this year that will copy our telemetry and have it automatically sent back to us. I hope your telemetry is APRS compatible so that it can also be distributed by the global APRS-IS system already in place. If nothing else, it only takes a leading byte to make it aprs compatible. We have already implemented the ability to send APRS emails, but would now like to do the same with twitter. Yes, Emails automatically work for anything that can digipeat because APRS-IS stations automatically link those packets into the APRS-IS where they are picked-up by existing APRS-to-Email engines. In this case then, the ability to send a tweet via APRS is simply an application that monitors the APRS-IS for any APRS packets that looks like they contain a tweet. If we do not already have such an engine somewhere in the world, then we do surely need one. And so your request is a good one. And this is basically what PA3GUO is suggesting below..

In conclusion, I guess I will have to either (1) Replace the azimuth portion with a G-800 using a seperate control box for azimuth and elevation or (2) try to replace the azimuth portion with a G-450 rotor. Or: (3) Purchase a replacement G5500 Az motor from Yaesu (they should be back in stock now?) (4) Send the problem motor to a motor repair / rewind company (maybe a few hundred $) (5) Rewind the motor yourself (doable, but it takes a while) Good luck, and 73! -Dave KB5WIA ___ Sent via AMSAT-BB@amsat.org.
