My Ver 11 build had 6-7 inch display cable 3.3 volt too, never a glitch. Ver 12 had glitches and freeze ups with any code I used until I slipped some ferrite sleeves over display and front panel

You can always request past tax returns from the IRS. Although - maybe not now. I hear they're a little short-handed. - Jerry, KF6VB

Jerry, You might also want to look into the Wiki, particularly the section on USB Audio: https://github.com/K7MDL2/KEITHSDR/wiki/48KHz-USB-Audio And there is also the Keithsdr discussion group, where

It’s definitely either the PCM5102 or the PCM1808, or the circuitry around those parts (I’ll bet you have a solder bridge or a bad part)… and remember that could be at those parts or at the

Thanks Bill.? I have done this with the RF board disconnected and the audio hat off and I get the same result. I'll try reinstalling the A/D and DACs but in the mean time, can I buy a set? Thanks for

I've pondered this question as well.? My 4SQRP kit T41 has an 8-9" cable between the display and main board.? Besides a few glitches early on, which I think were software related, my display has

Yes, thanks for sending...

I'll ask him, but I don't think he does. I have an infrared "gun" that I might poke around with. I'm gonna try the freezer thing too. Jack, W8TEE

I will give it a try. At this point, I would put salt on a swallow's tail if I thought that would work. I did back up my personal photos, but not my past tax records. I also had about 8 months work on

I can confirm the Hex code works fine, I have not explored all the options but it is working. I do have ferrite sleeves on display and front panel ribbon cables, that solved a lot of issues. Tim W4YN

Jack, Put the failed drive in a zip lock bag, then that in another zip .lock bag. I usually put the double bagged drive in the freezer for at least 24 hours. Once you take it out of the freezer, you

*** Does Al have a infrared camera? I saw a video where somebody fixed a dead SSD by imaging it - and quickly finding a shorted electrolytic. The shorted electrolytic got hot, and the camera saw it.

Jack.. .you said you want a new V12 RF board? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch - K9ZC Staunton, Illinois Owner -

Mark… I’m fully restocked with T41 boards… latest revisions too. I have at least 100 of each board gearing up for Hamvention. Unplug the RF board so its just the MAIN board and see if it still

With the addition of the following: 1. Change the following capacitors to 20pF - C33, C37, C46, and C54 2. Replace capacitors C35, C48 to 0 Ohm resistors (eg jumpers). Just mount them on top of the

Hey yall' I've tried everything I can think of.? The pulsating noise corresponds to the sclk signal (pin 13 led which also pulsates) which seems to be modulated by the spectrum update rate that is

I have the C boot drive which is a SSD, but only 500G, my D drive, which holds everything and is 1 TB and the drive that died, and drive F which is a 2T hot-swap backup drive. D no longer shows up in

In terms of reworking an existing board it looks like I need to: 1. Remove U19, U20, U22 and U23 along with associated capacitors (capacitor removal looks optional as they are no longer connected).?

It seems to be a combination of things (not just one)… weak SPI line drivers on the Teensy T4.1 and cross-talk (capacitive coupling) between the data lines that gets worse as the cables get longer.

*** That sucks. Did it die completely, or just lose data? Sometimes they can be read by putting the drive in the fridge. I have a unique system. I don't keep anything important on my desktop PC.
