21. Re: [RTTY] TinyFSK modem for 45 and 75 baud (score: 1)

Bill asked: and PTT does not do? Hi Bill,   Here's a concrete example if it will help.  I have a note here from Jun 7 of this year that I observed W6WRT with a stop bit length consistently at 37ms.

That's a good point, Andy--we're all assuming that the stop-bit tracking routine in 2Tone is accurate. You could always put a scope on the logical output if you really wanted to look at the waveform

  I asked G3YYD how the stop bit measurement works.  Since people might be tweaking things it would probably be good to know what exactly we are lookingand just as importantly what we aren't.    In s

This will be fun, I promise. Kai brought up a comments by Dr. Edgar Callaway, N4II, that saying that an actual real experiment was cut short because of the outdated symbol rate rule.  I've been throu

Joe and Chen have skipped ahead to the *double-secret* bonus round that I wasn't even going to tell you guys about....but yes, rectangular pulses are really poor way of going about this. Given the nu

Ok, I think we've gotten to the issues with the experiment.  I'm sure our ever-patient list admin is probably sweating a little and we can give him a little rest.  This little really isn't about the

Hi Friends, The talk about encryption is an interesting issue and in fact came up last year in a petition to the FCC.  You can read that and the comments to get an idea about what the motivation is a

Dave and the Group;   Apologies if this goes far afield for the RTTY discussion, but I'm just trying to provide some background data that is helpful when looking at the "big picture" around RM-11708.

Larry,  I fiddled with this a little over Christmas when someone else asked the same question.  I don't use WinWarbler, but I did download it and play around with it (sans radio) while on vacation.

Mark, What you are seeing is N1MM's incomplete implementation of the FIGS-to-LTRS conversion. It's been this way since the dawn of time. The top row (QWERTYUIOP) converts to the FIGS equivalent and

I've updated TinyFSK to be compatible to both USOS and non-USOS demodulators.   This results in a few extra shifts being sent in most messages (typically 2 or 3 in an alphanumeric exchange like CQWW

I remembered the EXTFSK actually sends the bytes to the monitor window.  Thankfully, at least according to the byte stream in the EXTFSK window, the help file is misleading.  The TX-->USOS in MMTTY o
