Posted in the VARA support group Latest version , saves upto four separate CALL/Key combinations All other functions remain compatible , Ie no change to ON-AIR requirements /

I dabbled in the WAE RTTY contest this weekend, first RTTY contest in a couple of years. What surprised me was how effective decode was on quite weak signals. Using just 100 watts with homemade

Hi All, What amateur radio ground station would be required to work the Lunar Gateway (LOP-G) ? The challenges are huge, but achievable. See the discussions at the new Lunar Gateway Amateur Radio .IO

Preliminary block diagram. Proposed by Michelle, W5NYV, of ORI. KC9SGV

Details are forthcoming. But it could be via VOIP, Skype, Echolink, www.remotehams.com Or, VHF/UHF, HF. Also Skype video, FaceTime, etc. Preliminary ideas, some of which will not work for Emcomm, but

K3SIW resumed sending Opera / op32 on the USA LOWfer band , previous best distances KU4XR with multiple decodes Previous results have been quite 'amazing, considering ,LowFER transmitters

Springs to mind , How is the aggregator accessed ? 73-Graham g0nbd

Combines all analog ham radio inputs. SSB, FM, CW, etc. Digitizes it and multiplexes it. Then uplink transmits it as a digital TS (transport stream) to the satellite. KC9SGV

Not sure what this implies. Any guesses? Ted WA7ZZB

Gang, We are pleased to offer the QRPGuys DSB Digital Transceiver kit. It includes three easily changed FT8 band modules for 40/30/20m. The kit uses all thru hole components. Price is $40. We are also

Very interesting, thanks for the info and the link . Andy

Echostar 9 So, there is a proposal out from ORI (Open Resource Institude) for rented bandwidth on Echostar 9 at 121 deg West. All the FLdigi modes will be able to be repeated by it. The uplink is via

Tony . These modes are ' base band heterodyned' as in the generation is performed at the base band , in this case audio , the ' waveform' is then heterodyned / mixed to the wanted

Graham: Thank you for that explanation. I can see how the CW hard-keying analogy could apply to digital. If this is something inherent in FT8, the side-bands would worsen with

If you are interested to find out more about the efforts to secure our own GEOstationary satellite over the Americas, please join the new GEO IO group. All digital modes will be possible through

Hi Tony May be aggressive is a subjective assessment , If CW tx , could be described as Hard/Aggressive Keyed , that would give the same results , Ie , Soft keying / envelope shaping ,

Graham: Single-tone modulation shouldn't produce inter-mod products, but some of the FT8 signals behave that way as if there were 2-tones in play. Could you elaborate on
