Before I start I will apologise to 90% of the users on this group because it might offend....THIS IS NOT MY INTENTION. To Carl Schlueter..... I have to ask if you are really a licensed Ham ? The

Anyone who cannot copy the Sbitx_V2 image to the SD card should not want to operate a radio with Raspberry Pi4. First you need to learn how to use the Raspberry Pi. Before I bought a Sbitx_v2, half a

Some of us buy a nice shiny sports car and have it serviced at the import dealer and some, like me prefer a Triumph TR6 that requires a lot of personal attention and work.? The HF Signals products

Hi all, Thanks a ton for the info there OM. I really liked the sBITX and contemplating buying when they have more pament options other than Paypal one day, encouraged by a 40m bitx, a multiband BitX

Ultimately I ended up using the pi username (which the installer strongly recommended not to do so, but I suppose it is a nonissue considering the use case). I also had to make the appropriate changes

Synopsis of the issue: my assembled sbitx v2 What for all of about an hour. Then it started to blow fuses. Soon as they flip the power switch fuse would ?blow. Contacted sales support, Thomas, and

I have refactored this code. I am working on some UI tweaks. I will push this soon as v3. It is a major software upgrade in many ways including UI changes

Yes you are correct about the LO. The problem was that the mode was being changed in at least two different places, so there was on one place that I could put code to detect that the mode had changed

The lo is changed only in sbitx.c. There should always be just one function tk change on state. The functions in sbitx_gtk.c are higher level functions that build on top of r1:freq like rit, vfo a/b,

Thanks for sharing that.

Dr.Slump you have addressed your message to a "user group". Try a different address for your problem. -- *Bob Johnson Jr.* *Tejas Model Shipyard* Lufkin, TX K5LFK *MODERN TECHNOLOGY* *OWES

great work, gang and great explanations, thanks! Gordon KX4Z wrote:

My solution was to put the change to the LO in both places where the mode was set. On my todo list is a re-write consolidating the radio commands into a single place where changes like this could be

Ok. Never mind. I just brought a few plugs and the one that fits is a PSK 254. Just in case somebody else is searching for this.

That's what I am looking for too. Did you come up with a solution for this? And are your code changes public somewhere? Thx

That explains something I noticed with my code. The audio sounded fuller. That’s due to the filter skirt difference. -- 73, Mark, N8ME

Mark, I just remembered. The 40 mhz crystal filter is sharp on the upper sideband and shallow on the lower sideband. Using it as an upper sudeband filter will make the opposite sideband

Well, I hacked in the code to change the Local Oscillator (clock 1) between 40,035,000 (current default) for USB modes and 39,987,000 for LSB modes. Seems to work.? I still need to adjust the

Ah, Harry Nyquist ... I remember as an engineering student at North Dakota State University learning that Nyquist was a graduate of the University of North Dakota just up the road in Grand Forks.

I am thinking of doing it. I hadn't seen the comment in the code. I just thought I'd ask if there was some compelling reason not to try. Why spend a lot of time on something that you had already
