PSK on ubitx and sbitx
|
hello,
?
Anyone trying PSK? you can do keyboard to keyboard comms with the Author.I made contacts the other day with my ubitx v6 on PSK and i was on 20 meters.Didnt overheat the finals and purred like a kitten. qsos lasted about 20 minutes for each contact. exchanged antenna,inof rigs,ages, weather, and exchanged conversations about some new antenna builds involving the TAK-TENNA.Pretty cool.
?
.Virginia, Nebraska,California. Canada ......Not bad for a homebrewed vertical from a $35 dollar extendable paintpole 3 ft off the ground being fed with rg6u quad shield cable.Not bad for a few watts the ubitxx puts out on 20.
?
PSK is underused so lets get out and use PSK. I know some will say whats the use when we have ft8, but i get tired of zombie contacts.
?
Anyone for PSK? Plenty of freeware software out there.? one of my old windows xp laptops which i dug out 2 weeks ago to play with it, im using digipan. very easy to run.100% easy to install.
?
Pretty cool.
?
PSK. used to be king and should still be king in my opinion. One of the ops was thinking of starting a PSK net.
?
PSK, my fellow ubitxers and also you sbitxers. 20 meters 14.070 is pretty active with the few thats on. Today i seen a couple of DX on PSK.
?
Right now, reporter has sv8rv,sp2omo,dg8rw,f4fvw,f4prv,,gm0ivq, oy1r(faroe islands). I did a search of stations sending and this was the DX stations.
?
So any of u ubitxers/sbitxers want to do Digital modes with keyboard to keyboard,get back to PSK.

I want to try it, but have not had much luck with digital software, I don’t use Windows so what I run needs to work with Linux or Mac OSX. Hoping it will work on the sbitx but not had too much time to play and to be fair the sbitx is possibly on its way to market so to speak but other options will I hope be available as I want to run PSK and JS8 at some point in the near future. Talking about PSK, there are so many different flavours, is PSK31 still the standard common flavour in use these days?
One of the reasons I don’t use windows and there are many, is that for radio use there are too many driver related issues and with the frequency of updates needed, they quite often get broken by the updates. I have tried and inevitably always end up reverting to Linux on my Raspberry Pi based pc in the shack cos it just works :-)
We will work over one of these modes one day :-)

Paul,

I use a macbook pro usually unless im playing with older laptops and such. Linux and Mac mostly. cocoamodem and multicocoa for Mac is available. just have to do a search.
?
with my old old laptop i installed digipan. and it worked flawlessly too. fldigi has a mac version too.

I use fldigi for psk on the sbitz v3. just need to make sure your in digital mode and change the pitch on the sbitx software to the signal coming in on psk on fldigi.
I find if you change the screen size to medium you can get both the sbitx and fldigi software up together. Then it is easier to see the psk signal on fldigi and change the pitch on the sbitx control software. |

Thanks David. During the sun minimum PSK was how I made contacts and during the pandemic is was how I got "out of the house." I have an sBitX but have not gotten fldigi to behave on it thus no contacts yet. So far I've not been able to diagnose it but I've been too busy to spend the hours it seems like it will take. Maybe with winter I'll find the time. It's a great low power mode.

I have a 7” external touchscreen that I found on AE a few years ago, 1024x768, just big enough for some of those “desktop” programs to fit, so that I can see sbitx at the same time on the internal screen. It doesn’t run down the battery much faster either, when I go portable. And I started hacking on the main ui file on wsjt-x to get the main window to resize smaller when I want to shrink it down. Reducing margins, minimum sizes and so on… it’s possible to have all the same stuff fit within 800x480, I think, but I didn’t try it on the sbitx yet. Soon. I see we seem to be running the audio through pipewire-pulse on the pi. So I think it should be possible to configure it to send audio streams across the network; then when I’m at home, I ought to be able to connect from fldigi, wsjt-x or whatever on my Linux machine to the sbitx, including the audio stream. Is anybody doing that yet, or you’re just running analog mic/line connections when you want to use a separate PC? |

Shawn, Im just running the patch cables from rig to computer. no signalink or nothing, but im not having problems from hum or anything else. Never tried Olivia. not familiar with it.I think they had a contest this past week or part of the weekend. loads of rtty and such. I dont own the sbitx yet. still at the ubitx v 6 level right now.HI HI 73 David ac9xh

I make regular use of js8 on uBitx V6, running js8call on an Asus eeepc 900 with light weight Linux (AntiX) O.S.
?
CAT control is via USB. Transmit and receive audio is connected via homemade cables, between radio front panel jacks, and computer mic/phone jacks. It works very well.
?
Fldigi also functions with the same setup.
?
However, thus far, I haven't made a QSO with any of the digital modes available in Fldigi. The many modes are confusing to identify (when observed on the waterfall). If PSK31 is one of the more popular (as mentioned earlier in the thread), does it have any real advantage over js8. (FT8 with wsjtx also works well with this setup. However, I prefer a mode which can be used for a real conversation, rather than merely exchanging QTH and RST.)
?
How would you compare js8 and PSK31 (or some other mode that works well for you)?
?
Thanks for your thoughts!

JS8 is I believe and confirmed with this video link () is an evolution of FT8 and is my next go to as I prefer to have a conversation rather than the robotic qso’s of FT8.
However I do like FT8 almost as a test program in order to to prove how far you can be heard with the least amount of power on different antennas particularly when operating /P as I do quite a lot. Its also a quiet mode when away in the motorhome and I want to play radio early in a morning while the xyl is still sleeping.
I have put the sbitx through its paces in a digital contest and it failed on me when I tried to use PSK/RTTY with FLDIGI so had to make do with only FT8 but managed a creditable
3rd place in the WAB digital contest earlier in year.
The confusing thing now with PSK is that there are many different flavours of it so difficult to pick out which flavour is being used, that may be why FT8/FT4 have taken off as they have. I do still hear RTTY on the bands so thats another possibility too. Need to find a Linux based alternative to FLDIGI I think for other digital modes and thats where I think JS8Call fits the bill as an alternative keyboard based communications mode to have real conversations digitally?
