Hi Randy 8 tones, and they constitute a 75 (?) bit message. Callsigns are basically looked up in a tables based on the bits sent That’s really about it Ria N2RJ

The QEX article explains all: https://www.physics.princeton.edu/pulsar/K1JT/FT4_FT8_QEX.pdf It's basically FSK, plus error correction and a lookup table of callsign and other data permutations. This i

DAX is Digital Audio eXchange. It’s a virtual sound card driver for Flex radios allowing application programs like WSJT-X to send and receive audio to the radio without having to use audio cables. Ria

MSHV has multi answer and full automation as well, unfortunately. Ria N2RJ

I absolutely love this idea. Perhaps you can ask the RSGB or some other group if they would be interested in managing such an award? Ria N2RJ <mcquiggi@...> wrote:

I second the NTP distribution from Meinberg. Anything else will get you the same problems as dimension 4. I have to keep time for regulatory reasons in the financial industry to no greater than 50ms d

#Timesync

Meinberg avoids sudden shifts in the clock. It’s also set and forget, completely unobtrusive. This is why I prefer it over nettime. Ria N2RJ

The error is not fatal. You need to go in your settings under security and allow it. This is pretty standard for Mac. <km6hk@...> wrote:

The packages are for buster. You’re running stretch which seems to be not supported. You’ll have to upgrade to stretch at a minimum, sorry. 73 Ria N2RJ

Minor correction (so there is no confusion): pi@myraspberrypi$ sudo dpkg -i install <whatever you want to install> should be: pi@myraspberrypi$ sudo dpkg -i <whatever .deb you want to install>

I got a Flex in 2016 so I've not had to use a sound card interface since then. Good to know that Tigertronics has resolved the issue. Ria N2RJ

I had one and the noise floor was very high. There are mods but I’ve never tried it. 73 Ria N2RJ

Well, considering that the timings are known, as long as you "play" the file and synchronize to 15 second intervals (or whatever it is depending on the mode), I don't see why not. Ria N2RJ

Like I said, a 73 is not necessary to have a valid QSO. But some people are adamant that they won’t log until they receive a 73. You may have sent it but they haven’t received it, probably due to prop

Some don't log unless they receive a 73. Even if they've confirmed both signal reports. Weird. 73 Ria N2RJ <n0igu@...> wrote:

We really need to re-think this. SSB, CW, RTTY and non-timed digital modes: Typically DX calls on one frequency, she/he listens on another single frequency or a range of frequencies. Callers call on a

Works fine here. Probably on your end. 73 Ria, N2RJ
