I have it set for 5v. I have checked the voltage at pins 3&4 on the display and it is 5v. Tom

My wish is that eventually its related to something… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois

Thanks Jack.? I commented out the "floor=0;" line 430 in ButtonProc.cpp in case anyone wants to tinker.? Works great !? I like the results with the noise floor just above the horizontal axis.?

Tom. Here is a WAG, do you have the 3V/5V selection jumper in place on the main board for your proper display operating voltage? Rick KN4AIE Sent: Saturday, April 12, 2025 6:27 PM To:

I got the main board working. When running the test program it finds the teensy hat, the switch panel and ?encoder boards. When I run the display test it comes back test completed but the screen

I changed the check for negative values some time ago...not sure why it was changed back. I prefer to have the noise floor sitting just a smidge above the horizontal axis. I'll look into this. Jack,

What you've done is fine.? Some of us have coded an auto noise floor adjustment for the v11.? I suppose it will get to the v12 software at some point.

Generally when my spectrum is all yellow & angry, I crank in some receive attenuation. - Jerry, KF6VB

Hey 'yall, I'm still working off a 2' wip in the basement, so not the best environment.? Lots of noise on 20M but still picking up 4's and 5's !!!? Anyhow, I may misunderstand what the book (3rd ed)

Hi Phil. Thank for replying and your observations with it.? I am looking at it for the same reasons you did, size and connectors.? If I need something better, we have some R&S equipment, at work,?

Hi Bill, Following your recent post about UK/EU orders and the fact I have not received an invoice yet, does this mean that you will pass on my order or should I now order from Andy directly and wait

Hi Duane I have one, have been very happy with it so far, apart from the soft buttons being a bit "bouncy".? Have not yet worked out how to do screen calibration, but that will probably fix it. I

I do have part of my new system for invoicing for boards and kits up and running. Invoices for will come to you from Paypal and have the email address sales@...

These are not perfect, but they do work and they are cheap. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton,

Tnx Dr. Bill I had to use some on the 4SQ kit for audio to phones and speaker. I also got them off AMZ however they were bare xformers. The RatShack ones I had created lots of loss, ones I found did

Here is the price list for the USA. It lacks shipping expense, but you can us it as a gauge… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big

I have created a spreadsheet for you to express interest in boards and kits from Bill, K9HZ.? There are currently no prices on the spreadsheet as these will depend on the quantity requested from

For those of you in the UK/EU. Andy Rutter, G8HCK, has graciously agreed to distribute T41/ K9HZ/ K9HZ-KI3P boards and kits there. I'll attempt to ship him a load of stuff and he will make

I ran across something that I need to share. I bought a two-pack of audio transformers on Amazon that work very well for the cost. Works great to break ground-loop issues, hum, etc. Cheap too. and a
