Re: Trouble ahead- mixed signals?
¿ªÔÆÌåÓýHi Vic, Thanks for your
reply. I was pretty sure that was your point of reference but
it is not safe to assume. My only interest in WSJT modes is to
evaluate propagation and I don't transmit with it (but I
might). I have had some contest and QSO party contacts that
are more interesting. I am glad to have those stations on the
air and when I want them I always know right where to look.
Just like WWV. I have used the other, load handling, digital,
teleprinting modes and enjoyed them the way you have pointed
out. Paying attention to "on topic", my uBitX is one radio I
use to copy those signals these days. I will try LinPSK on the
olde Pi just to see how it does. Once upon a time my computer was big and heavy and so was the display even though the image was small and often hard to read. Now my computers are tiny and easily ride in a shirt pocket. They can reasonably operate from a small battery pack. My displays are on 30 inch HD television screens now :) I have one a little smaller that can also operate from batteries:) And another that mounts on a Pi case! The weight and bulk of the vacuum tube radios could induce injuries and required a lot of power that was wasted in heat energy. Now we can carry some of them in cargo pockets and operate digi modes walking through the state and national forests! As my grandfather used to say - "the only thing good about the good olde days is they are gone!". My 'legacy Pi'
will be used in cli mode in the kitchen to present recipes and
manage grocery lists. Just not both at once! 73, Bill? KU8H bark less - wag more On 3/23/21 6:32 AM, Vic WA4THR via

Yes, Bill, all my comments about the "little Pi" were referring to the Pi-Zero, actually the first and only Pi I have ever had. I gather it runs at about the same or slightly faster than the original Pi, so I think the LinPSK program would work there. That program has no issues on the Pi-zero. As I recall,the Pi-4 is something like 10 or 20 times faster and it is commonly used for decoding FT(x) stuff, but WSJT-X is still a bit marginal on the Pi-zero. I have slowly got it within 4 seconds of finishing decodes before the next cycle (I think it was like 20 seconds behind when I started), and that is with a 10% boost in the clock speed. Still, it may be good enough for my occasional use of that mode. I have made a number of contacts that way. |
