Great idea! I am compiling and using the beta's (latest 2.6.8 really nice with the UI updates!) but I can only get them to compile in 32 bit mode, not 64 bit, so would like to learn what I need to do in VS to get that to work. I'm pretty new to Visual Studio. I'm using the latest version with no pro...

I assume this amp uses an LDMOS chip and if so, 10 watts is WAY too much drive. LDMOS chips run 28 to 30db of "amplification". That means at 30db one watt of input produces 1000 watts out. I have a homebrew amp that uses two LDMOS chips and the maximum drive it takes to produce 2K out is 4...

I just did the 1903 update tonight fully expecting the audio and other things to break but for some reason the Microsoft Gods took pity on me and everything worked just like it did before the update. Who would have guessed that?

I use VMP and the Behringer 202HD and see almost the same numbers as Tony. I actually see 60db under the same conditions you just described Scott. I think this is just a difference in gain in JTDX vs. WSJT. I frequently decode all the way down to -26db signals and work them with JTDX so I know the s...

Hi Gary, I wonder which way you adjusted your bias to improve the IMD? I found that by increasing the bias on the PA in my Anan some time ago the IMD without PS running improved from the -20's to the -30's. This also resulted in an improvement with PS running. If I recall correctly, I changed the bi...

Scott, thanks for mentioning "cycling one of the manual checkboxes" to fix a "runaway". I have these sometimes too and it happened today after I read your post. I cycled the checkbox on the "In" box and it immediately stopped and behaved afterwards. I have been seeing t...

Hi Brent, I've also been working with Thetis and playing with VAC. What I have found so far that works at a setting of 192k is a buffer size of 256, port audio both set to manual and zero, and both ringbuffer settings of manual and at 25. This seems very stable with quite a lot of other things runni...

I tried out the diversity option on Thetis 2.6.4 last night on 160m and it seemed to me to be easier to find the null than Protocol 1 versions. I did notice an anomaly though. Several times, when I had nulled out interference, I found if I pressed the Disable button to disable diversity then pressed...

I'm getting an "unhandled exception" on close of 2.6.4 frequently. I click the "Power" button, then click on the X in the upper right of the window to exit the program and in about two or three seconds I get the error. Not every time, but frequently. Below are the particulars of ...

I've used Com0Com for years with various flavors of Windows and various software with no problems at all. It's free and just works.

Joe, next time it happens, if you haven't before, make sure you not only power down but also turn off the power switch on the computer power supply for about 30 seconds. Just shutting the system down doesn't kill all the voltage to the motherboard.

Ok, Scott, got it. The problem is still the fact that Thetis is doing EXACTLY what the firmware did using Protocol 1 with Alex ON as regards filter selection. What Thetis is NOT doing is honoring the selection of 200D in the Hardware selection menu as regards filter selections and instead, I assume,...

Joe, thanks so much for your effort! I have been contemplating the hardware changes I would need to make on the 200D PA board to accommodate 80, 40, and 30 meters under firmware control and didn't really want to do them so maybe I won't have to if Doug adopts your code. In the meantime, I'm back to ...

Scott is, of course, correct. My mind is just not right.

73,

If I remember correctly, it's been a while since I looked at this, this attenuator is used for Ext2/3 input. I believe it is 20db, if memory serves. I used to connect my low band Rx antenna to Ext2 until I found that this attenuator is switched in and there is no way I found to switch it out. I now ...

I see there is no button for Alex on Thetis nor can I find a way to turn "Alex" off. By Alex, I mean firmware control. With our old software turning off Alex (pressing the "Alex" Button next to Mox) disabled firmware control but without the button I can't seem to find a way to do...

I just installed the new 1.3 P2 firmware and Thetis 2.6.0 and so far, everything seems to be working pretty well on my 8000 board. Still a lot of testing to do but the only thing I've found so far is there is a glitch with VOX operation. VOX engages smoothly but when it drops it does a double or tri...

Thanks for the comments Scott and Gary. My "gloom and doom" was really tongue in cheek. As I mentioned, I really don't see that the SD button does anything other than block you from selecting Split. It does not cause the vfo's to sync on my radio . I have to press sync manually. I worked a...

I have been using Stereo Diversity on 160m now that we are in a new season and find it very helpful as I have a low noise RX antenna and couple that with my vertical transmit antenna and find frequently it reduces fading considerably by listening to both antennas. The problem was Split operation whi...

Well, at the risk of saying something that will be disagreeable to some, this seems to me to be a simple problem. Simply limit the Ethernet speed to 100mbps in the firmware for Angelia and down and the fuse problem goes away. Everyone can still run Protocol 2 and Thetis and those with Orion 2 boards...

HI Gary, I just had a problem and thought about you when I found and fixed it and wondered if it might pertain to your problem where you can't get the resampler to work or help you at all. Tonight I got on 160m and had a terrible problem with overflows/underflows going crazy. This was something new ...

My 160m USB, 2.7khz daytime noise level with the meter on sig avg runs -107/108dbm on my RX antenna system. The gnarly spur is around -98 for this mode and bandwidth so it is easily heard as it is about 10db above the noise level. Fortunately, my spur is out of the band so it doesn't matter to me. I...

Scott, interesting to hear that you don't have a problem with your 8000. Do you happen to know what iteration of 8000 board you have? There were several produced, it seems. Doug and I determined my board is version 3.2. According to Doug, there was 2.5, 3.2, and 5.0 version board. I believe the vers...

Hi Gary, Yes, I see both of them at the same frequency and those and the gnarly one are the only ones I see in that bandwidth. Interestingly, these smaller width spurs do not change frequency as the radio warms up. The Gnarly one does change frequency. It goes from 2.004mhz to 2.023mhz after warm-up...

I use an 8000 board and I have exactly the same spurs you show; the large gnarly one is at 2.0 mhz on my 8000 and the two smaller ones are exactly where yours are so if there is something defective with your 7000 it is also defective with my 8000.

Hi Larry,

I've never used MicroSoft Sound Mapper but I just opened Audio-Vac1 and set the Driver to MME and then looked at both the input and output and see the "Microsoft Sound Mapper" option for both. Don't know why you wouldn't see it too. I'm using PowerSDR version 3.4.9.

Hi Gary, As you can see in my picture, cores 5, 6, & 7 are obviously not following cores 0 thru 4 and are running at a lower cpu rate so the Affinity change worked for me. If you only moved the programs you wanted to core 6 and did not prohibit other programs from using Core 6 then that may be w...

Hi Gary, I thought I would update you on my fooling around with Affinity today. I decided to play with it to see what I could discover. I assigned PowerSDR.exe to cores 5,6, & 7. I assigned all the firefox instances, JTDX, and JTAlert to cores 0 thru 4 as these were the major users of CPU cycles...

Hi Gary, I supplied the info for all the modes the radio operates but certainly digital is your focus so I would try setting that to 128 buffers on the filter page, if it is at 64 and see if that makes any difference. I also run digital modes at 48K rather than 192K where I run all other modes. This...

Gary, I've recently been able to reduce my settings to the absolute minimum with rock solid performance. My Ring Buffers are 512, 512. I am running with Primary audio setting at 64 and VAC at 128. I have Buffer Latency at zero. I run HOURS with no uptick in overflows/underflows or OOOPs now. I typic...
