It’s out there… Here it is: T41/T41_V012_Files/T41_V012_Schematic_PDFs/T41_RF_Board_Schematic_V12.6_020925.pdf at main · DRWJSCHMIDT/T41

*** Do does my FTDX10. Well, at least it used to. It has a USB hub chip, a USB audio chip, and a USB serial-port chip. The serial port functionality died. I replaced the chip, but it's still dead. I

These double headers ( https://protosupplies.com/product/header-male-1x14-double-insulator/ ) may help. Ken will also custom build Teensy/Audio hat stacks (

Mornin' Bill: I'd like to order one of the new RF boards. Is there a new schematic for the board? I didn't see it on your web site. Jack, W8TEE

Ah Haw now that makes sense. I miss the old days of paper catalogs, I was looking for machined pin headers and got no where. I know they are out there, was easier to flip thru catalog. I have some old

To All, I also was having similar problems with audio hat and teensy pin connections. I found that the long pin headers have a pin that is flat .015 thick, were as the short pin headers had a .025

Bill, Did you get my note about changes to the component values for the SSB Exciter chain on the RF board? If not , I will re-send it. These changes enable the flat response and lower adjacent channel

Yep that’s right… John did that last fall. He also is the guy to get FM enabled as a mode… and the second receiver working in the T41. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ

Already been done with T41 v11, /g/SoftwareControlledHamRadio/message/29503.

Actually... My K3 does exactly that... one USB cable that everything flows over.... digital/CAT and Audio. I do have the schematics for that board so I can see how it's done from a hardware

BTW. the new stack of RF Boards here. have the following updates: 1. Removed all of the MF stuff but left the jumpers to CLK0 and CLK1 so that they could be driven from something else or checked with

*** OK, I just ordered two of those. I have other uses for it. I'd still like to get the software audio working though. IMHO 44.1 is plenty fast enough for audio - it's just if you want to move I/Q

Hi Jerry- I am already working on adding a hub to the T41-2.? I found what looks to be a good candidate on Aliexpress.? It's a small board. I wanted USB C connectors.? Here it is:

Since those native serial ports are all at digital levels (0 & 3.3VDC, & inverted from normal RS-232), you'd essentially need any of a variety of common TTL-to-RS232 level convertor chips in order to

Or we could use one of the traditional serial ports built into the Teensy hardware. There are eight of them. But looking at the Main Board schematic, I don't see much in the way of unused pins. ***

Well… I have plenty of boards in stock right now… over 100 sets of every board gearing up for Hamvention. Main boards are $1.50 and offset boards are $0.50…. plus shipping Paypal fees, and tax.

Here’s another thing. There are other ways to interface USB to the Teensy if you need more USB hardware. The FT201, FT233, FT311, FT2222 are all devices that sit on one of the I2C busses as a USB

That’s a good idea and actually, I think I saw an article on someone using a USB server device with their T41. I don’t know how that works but its out there… Dr. William J. Schmidt - K9HZ J68HZ

Jerry: could you just use the standard Serial + Audio USB configuration on the primary microUSB port, then add an external USB-to-serial adapter plugged into the USBhost port & use that additional

There was some work done last year on v11 to patch the Audio library for USB audio at a 192k sample rate.? John reported success passing audio over USB to his Ubuntu box. I developed a PC server app
