Soundcard interfaces to existing voice radios were a good start, but it's time to move past them. I've designed several modulation and coding schemes to fit existing radios, and their inherently limited bandwidth is a major pain. For ARISSat-1 I agreed to cram everything through a SSB filter, and I'm not doing that again. Not only does the narrow bandwidth often limit the data rate to much less than what the link budget could actually support, but it enormously aggravates the Doppler problem. It doesn't help that there are no industry-wide standards for SSB phase response or computer tuning, or that every time you retune one (which is often) there is a poorly characterized phase jump. Doppler is much easier to handle at high data rates because it's the ratio of the symbol rate to the Doppler that matters, not the absolute amount of Doppler. Now that we have a variety of "pure digital" radio front ends to choose from, it's time to set aside the voice radio + soundcard model. Not only do the SDRs support wider bandwidths but they tend to be considerably smaller, lighter and easier to work with in software. Some, like the Funcube dongle, are even considerably cheaper than conventional radios. --Phil ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Re: [amsat-bb] going digital
Is there some reason why a digital signal cannot be passed thru an analog/linear transponder? What goes in is what comes out. It seems the lack of transponder bandwidth limits the digital signal experimenter... Maybe that is why commercial transponders on satellites are linear. They can take any modulation and retransmit it : AM, FM, PM or CB The biggest problem would be the taxi-cabs etc -Original Message- From: Phil Karn Sent: Saturday, July 19, 2014 4:24 PM To: Paul Stoetzer Cc: amsat-bb@amsat.org Subject: Re: [amsat-bb] ANS-199 AMSAT News Service Special Bulletin - AMSAT Fox-1C Launch Opportunity Announced On 07/19/2014 12:28 PM, Paul Stoetzer wrote: Are FM repeater satellites what we all want in orbit?

You will have changed the Icom address of one of the radios to allow control of both radios.. If the program starts - for example - with FO-29 choose the address of the radio at the 70cm antenna (downlink) as the first address value in the "Radio 1" section of menu "Radio Setup". and the address of the radio at the 2m antenna (uplink) as the 2nd address value. Uncheck the option "Satellite mode" and check the option "Autotmatic Rx/Tx change". Withh FO-29 (v/u) the program will then steer the radio at the 70cm antenna as RX and the other at the 2m antenna as TX with FO-29. You can tune the VFO dial of the RX around the passband and the TX will follow. When you switch to VO-52 (u/v) the program will exchange the roles of the radios as RX and TX. You can tune the dial of the radio at the 2m antenna and the other will follow. 73s, Erich, DK1TB - Original Message - From: "Ronald G.
