*** Wow. What a mix of technologies. FPGAs at one end, a tube at the other! My first amp project used tubes. Back in high school. 4 6LQ6's stuffed into an ARC5 transmitter cabinet. I think it did

Ron: The cost from Dr. Schmidt for new 12.6 boards is minimal, but if you have boards with the SMDs already in place, I would finish the kit with what you have. If you're not happy with what results,

Great, very good news as I ordered it this morning. Question regarding my kit I'd left boxed up since Dec 2023. My boards have a 2023 date on them, they also have ver 009b. Looking at the images of

Good work Tim! Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner – Operator Villa Grand Piton - J68HZ

Not readt to sell yet. I keep thinking up stuff to put on it for new purposes Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch – K9ZC

Ok great. A block diagram would be good to start. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner –

The only skill im missing is programming the FPGA… the rest of the hardware is easy. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch –

As promised here are a few pics of the inside.... Many boards are mounted horizontally, on aluminum and 3D printed standoffs. The PA and driver and UI systems are all vertically mounted. The LPF-BPF

I do plan on sharing, William, but any sharing will not be anywhere near how nice Al and Jack have described their system. I have stood on the shoulders of much better people than I to get this

Very nice Jerry. My amp is "hollow" state using a 3-500Z. Always wanted to build a tube one and I finally did it. I didn't cover 160M, but may add it some day.... or a dedicated amp. I do have some

Anytime, Bill. Be glad to help. Russ

Nice!? I used one of the other SMA connectors for my Beverage so I could make sure it gets disconnected during transmit.? The PIN Diode changeover would be nice. I made one once, many moons ago, but

All boards complete (Except PA) and building ked out Biggest headache was caused by using Chinese Long pin header in Teensy. All kinds of issues croped up. Changed to Long Pin headers made correctly

*** Very cool, Russ. What sort of homebrew amp are you using? I use my T41 with an amp with an MRF1K50 - RF card & LPF kits from W6PQL, a Chinese cell-phone-surplus rack mount power supply, a 4-inch

I have 65Mhz ad/da and intend something similar care to share your work? [email protected]> wrote:

Oh yeah, BTW the PIN diode version of that TR board has additional inputs for RX antennas (up to 4) and the connections for the Auto Tuner. That will really change things for use in in the field. Dr.

Yeah we need to talk. You have more skill that I do in the FPGA department… where I want to go next. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner -

Last evening, I finally got my version of the T41 on the air for an extended period of time on 75M. Talked all over the US and even down to British Honduras with my home brew amp running about 800W. I

If you order the 5V one, it's always an option to go with 3.3V. If you order the 3.3V option, it may or may not be possible to use 5V. Because for the 3v3 one, they may or may not stuff the 3-terminal

I did not have any trouble uploading al looked good at first. There sections of 20M that had wide sections of high noise, sometimes triggered with tuning with main encoder. After doing a rx
