Re: Need to restart Thetis to restore amp after fault?

I believe this is an issue with the Drive control. I see it frequently. I will adjust the drive control to, say, 22 and press tune and get close to zero watts out. Bump the drive to 23 and then the output is just fine. Been doing this a long time for me. Next time you see this happen, just bump the ...

Re: Wave File Options Menu Missing

I mentioned this to Doug several months ago and he fixed it for 2.7.0. A version or two before 2.7.0 was missing the options tab which caused problems trying to get the audio record function to work properly.

Scott, it has always worked that way, to my knowledge. Seems like I've been using that function for quite a while but I'm old and who knows?

Actually, you can expand the panadapter scale without going into Setup. Just right click on it, hold, and move the mouse up or down. I do it all the time.

Re: 2.7.0

Larry, Cat 5 cable is not designed for gigabit speeds. It will sometimes work, but work poorly. I suspect this is indeed your problem. The Cat 7 cable should solve the problem. Anyone running Thetis should definitely check their network cable and make sure it is at least Cat 5e preferably Cat 6 or C...

Re: Rx Ant not working from main screen

Scott,

You are correct and the one on the left in my diagram is the 10db pad and it was being energized when Ext1 was being used as a receive antenna. Perhaps my 200D was different or defective.

I believe I mentioned I didn't see it in the 7000 schematics. I've pasted below the 200D a partial from the 200D schematic that shows the pad.

Re: Rx Ant not working from main screen

Rob, There is another issue of using an "Ext" port on the 200D series PA board for an Rx antenna. It costs you 10db of signal strength due to those boards having a 10db pad in the signal path for the Ext ports. If you feed a signal into the radio through and Ext port and then switch to an ...

Re: 2.6.9

Thanks for the info Paul. I guess the sidetone addition in VAC was part of the C3 QSK work. I hadn't paid attention to that as I wasn't interested in QSK so I missed it.

Interesting about the delay changing.

My Icom IC-7300 doesn't nor do others I have checked. Frequency never changes with ANY mode change.

I've noticed an anomaly with frequency and mode. If you set a specific frequency with Thetis and then select ANY of the modes AM, LSB, USB, DSB, FM, DIGL, or DIGU the frequency stays at what you set it to as you cycle through these modes. However, if you throw either CWU or CWL into the mix and cycl...

Re: Anan 7000dle and pure signal setting

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...

Hi Gary, I wonder which way you adjusted your bias to improve the IMD?

Re: Protocol two across a LAN

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.
