After learning that Hans Summers was at Dayton Hamvention promoting his QMX which can now operate SSB using Polar Modulation, this got me thinking. Has anyone considered a T41 using Polar Modulation?

OK, I've pushed these changes to github. I tested my radio with both settings and can't say that I can hear a difference, but the changes are more correct. John W2TX pointed out in an email that the

Yes, I've used 279 for the size of FIR_dec3_EX_I_state and FIR_dec3_EX_Q_state.? Also, I set the size of FIR_int3_EX_I_state and FIR_int3_EX_Q_state to 151 in lines 1132 and 1133.

The size of the FIR filter's state vector should be numtaps+blocksize-1. For the decimation filter in question, this is 24+256-1 = 279. To be explicit, can you confirm that changing the sizes of the

I tracked down a problem I was having in SSB transmit to the size of the decimate state vectors, FIR_dec3_EX_I_state, FIR_dec3_EX_Q_state.? If these are allocated to DMAMEM, the RF out on the RF

Lynn, KU7Q, is using this in his CTR2-Dial Product. It's intended for use with remote operating apps that supports MIDI commands. It works great with Marcus Roskosch's Apple products apps.

Ken The suggestions from Jerry are good but they're not a permanent fix. The files in /tmp are exactly that: temporary. They will be recreated as and when needed the next time you boot the system. The

What are the audio reports like barefoot? Jack, W8TEE

By way of https://makezine.com/products/boards/m5stack-dial/ I was just looking at this https://shop.m5stack.com/products/m5stack-dial-v1-1 With my limited programming skills it would be a coin toss

I should clarify that the "muddy audio" problem is not new with this version. The last version I was using had it also. - Jerry, KF6VB

*** Through the amp. I also use my FTDX10 through the amp, and people report crystal clear audio. - Jerry, KF6VB

Are you running barefoot or through your amp? Jack, W8TEE

Strange, both of my builds V10 and V12 have always received excellent audio reports. I have used several cheap (RS) elements in home made enclosures. Did you use the dedicated Mic ground? Tim W4YN

I just downloaded the latest V066.9 from Oliver's github. Trying it out now. People are complaining that my transmit audio is muddy. And with the transmit equalizer enabled, it's beyond horrible. I

except that the file mentioned doesn't actually exist! I solved the problem by downloading the zip file containing a conventional binary image.? Still have to set chown root and permissions though.

Screenshot of the code?? The code is available on my GitHub in the file keyer.cpp ( https://github.com/tmr4/T41_SDR/blob/dev/v0.1/software/T41_SDR/keyer.cpp ).? It's over 500 lines so I'm not sure

Thanks Terrance. I’ll keep studying this. I have 66_9 and will use my PC with WSJT dave

I will have to have a look. I did revise some of the fitlter designs in the last version. Al

The design stuff would be a whole page on its own. I may add that over time. I would have to do it with a lot of context added so it makes sense. Good idea. al

Thanks, Terrance. I will remove the CW messenger, but if you would send a screen shot of the T41 port, I will include that. Regards, Al
