W1AW/2
by W2JV 15 Jan '14

15 Jan '14

Hello, I will be active on all the amateur satellites from 1/22- 1/28 as W1AW/2. W1AW Portable Operations, ARRL Centennial QSO Party The ARRL Centennial "W1AW WAS" operations are taking place throughout 2014 from each of the 50 states, relocating each Wednesday (UTC) to a new pair of states (this week, Nebraska and Delaware. Listen for W1AW/0 and W1AW/3). During 2014 W1AW will be on the air from every state at least twice and from most US territories, and it will be easy to work all states solely by contacting W1AW portable operations. 73, Pete W2JV formerly WB2OQQ

APRS packet using Kenwood TS2000 and UISS software
by Rupesh Lad 15 Jan '14

15 Jan '14

Hello all, I am Ground Station Team member of COEP's student satellite mission 'Swayam'(www.coep.org.in/csat).Our Ground Station is functional with uplink and downlink capabilities and is equipped with Kenwood TS2000(having a built-in TNC) transceiver and Yeasu G5500 rotor system. With the vhf and uhf antenna available with us we have successfully received analog beacons from many satellites. To prove our digital capabilities we are focusing on having APRS contact with ISS. We use UISS software by ON6MU along with AGW Packet Engine to connect PC with TS2000. Using the software we successfully transmit packet on air as transmitted packets are clearly heard on hand held Yeasu VX-3R transceiver which is unable to decode any packet. Even though we try to digipeat and data is transmitted, we are not able to receive data on the software screen. whenever we have a pass of ISS some signals are detected and a receiving led glows even in squelch on. But the received signals doesn't sound like packet. Please help us in improvising our ground station for digital communication. Regards, Rupesh VU2COE

SatPC32 error messages in German
by Red Willoughby 15 Jan '14

15 Jan '14

Some time ago, I saw a post about a patch that would display all SatPC32 dialog box messages in English rather than German. It has really not been so much of a problem, but I would now like to apply that patch. My searches have not turned up the info to accomplish this. Could someone re-fresh me on where to access the info on that procedure? Thanks in advance. Red, KC4LE --- This email is free from viruses and malware because avast!

crude receiver
by Joe Leikhim 14 Jan '14

14 Jan '14

You could. My concerns would be: 1) Noise figure. You will need a low noise amplifier with sufficient gain to overcome the mixer loss. 2) How will you stabilize the frequency of the YIG? You may have better luck with one of the more easily attainable crystal controlled "Brick" oscillators. Hi all! Could I build a microwave receiver for satellite using a yig, mixer, the appropriate Local oscillator and an SDR dongle for receive of some kind? I do have an IF filter and so forth.

FUNcube Realtime data available as a .csv download
by David A B Johnson 14 Jan '14

14 Jan '14

Hi, The FUNcube Data Warehouse is now producing .csv files containing Realtime data channels. The data is produced every hour, on the hour and contains 3000 rows, starting 250 minutes before the last record in the database. As we do not have worlwide coverage, there will be missing segments of data. To overcome this, we fill the data with the last value before the gap. All records are have an associated 'satellite time' this is based on the known activation time of the satellite and offset calculated from the sequence number and frame type. The satellite is currently 3 hours 50 minutes ahead of the data server time. Please visit the Real Time Data page and click on the link in the descriptive text. http://warehouse.funcube.org.uk We welcome feedback on the format and content. Please use the forum: http://forum.funcube.org.uk 73 Dave Johnson, G4DPZ, FUNcube Team Member
