Re: RF Board update.
You can do it on your board by just standing the capacitor straight up in the air from the leg between Y1 and L7¡­ and the other side to a close ground pin. I did that and it seemed to work fine. Dr.

Re: [AmateurRadioBuilders] RF Board update.
I did. those are just BOM and schematic changes, not board changes so was easy to make. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal

Re: CAT
Yeah that's what the K3 has too... a TUSB2036 3 to 1 hub, and the three inputs are a PCM2901 CODEC, a FT232 USB to RS232 converter, and a USB connection to the PIC processor (for uploading new

Re: RF Board update.
My bad, I loaded the wrong schematic. If I want to add C74, is it a 0.1?F bypass cap like C85? Thanks! Jack, W8TEE

Re: CAT
*** 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

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

Re: RF Board update.
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

Re: Audio Hat Hangup
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

Re: Audio Hat Hangup
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

Re: [AmateurRadioBuilders] RF Board update.
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

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

RF Board update.
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

Re: CAT
*** 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:

Re: CAT
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
