What I don't understand is why NOBODY uses the pskmail arq chat mode, which adds an ARQ layer to modes like PSK250R, THOR22 or MFSK32. Why accept 5% error when you can have it 100% error free? Are you afraid your typing errors get to the other end undamaged? Rein PA0R MFSK16 always seems

a reason for No serial connections... Serial connections are so 1970's. My computer does not even have a serial connection. I'm also a believer in simplicity. Putting on a USB to serial connection is going backwards in the digital revolution. Same with the TNC. It would seem that the

[digitalradio] xastir or similar service/daemon 'back end' software?

Is it possible to run xastir (or some other similar aprs software service) on a machine as a service/daemon, and use a different machine to connect to it to view aprs maps? I have an old very slow machine that should be good enough to do the communications and data manipulation, but it is way

[digitalradio] DX4WIN - rotator interface

2010-02-01 Thread ve3pie
the info on the DX4WIN software says it is compatible with the sartek and hygain rotator interfaces. the sartek is not available anymore. I have the yaesu 2800 DXA rotator and a HAM IV rotor. what rotor interface can I use for DX4WIN? Is the idiom Press unit compatible or something else?

Patrick Although the amount of RAM may not be critical (provided you're not paging), the SPEED of the memory is probably the limiting factor. The summary is that in a modern cpu with multiple cores and pre-fetch pipeline processing, the processor can execute instructions faster than they can

Hello John, Although the amount of RAM may not be critical (provided you're not paging), Yes I agree. the SPEED of the memory is probably the limiting factor. It could explain why my two PC at 2400 MHz have very different calculation speeds (a ratio larger than 2), the oldest being the slowest

I'm pretty darn happy with the performance of Olivia without the added complexity of ARQ and the one on one aspect of the ARQ protocals. I'm not sure about pskmail arq chat mode, but some of the other ARQ protocals I've played with look like a mess when you're a station on the outside looking

Hey Dave! Would it then be a fair assumption that you would not care for the likes of ALE, DRM, PACTOR, Digi SSTV, Analog SSTV, the new sparky offering called WINMOR, ALE400 - they're pretty much a Closed Club, or Private Channel affair, wouldn't you say? I think there's some others, but suffice
