Karl, I found this link when searching for PuTTY on Mac: https://www.ssh.com/academy/ssh/putty/mac Note that there is a terminal built into the Mac OS, so you do not really need to download PuTTY.?

My current info: 1 - Raspbian Buster version 10 on Raspberry Pi 4 2 - QDX version v1_01a 3 - Built for 12 volts 4 - 12 volt LitionIon 5 - Rev 1 board 6 - I have removed the 4 PA BS170 MOSFETs and IC5

Just like with any other regulator design you want to use low ESR capacitors. MLCCs usually are, tantalums usually are, and disk ceramics usually are. Verify before whipping something together out

I don't know exactly why, but when I've had issues getting rig control to work on MacOS or Linux I've found that FLRIG is more forgiving. Try setting up FLRIG to control it and then set WSJT-X to work

Hi Bill, I just used the typical 78xx schematic and MLCC capacitors that I had on hand. E.g. Mouser 581-SA115E334ZAA or similar. I don't think the component choice is terribly critical, but MLCC is

Karl, You need to use a terminal program. Is there something on a MAC or a version of Putty? Look at the manual, the audio level needs adjusting. 73 Alan G4ZFQ

I am building mine for 9V for the same reason, to use with batteries. I have a couple of different switching converters and can always do a linear regulator for home use. I also think that 9V will

FWIW: JS8 is the mode and JS8Call is the application. So sayeth the 2nd line of the JS8Call.com website. After fixing my clock problem, I fired up JS8Call and sent out a "testing QDX" message. Got a

Gregg W7GRM..? I have been thinking on the same lines.. possibly overthinking as I look at your picture.. I have some 3s LiFiPo surplus batteries that should power the QDX and Raspi for a

Hi Evan, I just saw Hans' email with this request. Thanks for the reminder. And thank you for the link to the thread, I did search the groups.io repository, but did not find that thread. Here is

Chris, I am running the version that is available on the Add / Remove Software app in the Preferences menu of the default Raspian OS.? It is reported as v2.0.0 by K1JT. Currently, I have the Radio

Hello Karl, I am having similar performance running on a 12volt LiIon battery, Raspberry Pi 4, it is built for 12 volts, and version 1_01a (have not yet done the most recent upgrade).? Because of

Evan Thank you.? Which version of WSJT-X are you using?? I have selected the port which shows as 'QDX transceiver', baud rate, polling, other settings all as recommended by Hans.? No joy. Changed

Thank, Phil. I've been a Life Member of the ARRL since 1972--cost me $125; can't even figure out how profitable that's been! I hope the CQ column turns into a good resource for those hams who want to

Hi I was testing mine, and had a lot of spurious, when the power was 5 watts, all of a sudden the power dropped to 2 watts ( I am in FT8 mode) and used the tune button to check power. I initially set

I just finished my first successful FT8 QSO with?the QDX, so I know it's working, I am getting out and I can receive.?However, the RX level is very low: On the 20m band, with a lot of very strong

Hans, I have long expected there may be a few deviants lurking hereabout! ?BTW, received my QDX 50165 11/8, assembly went well. ?Still looking my work over, so no power applied yet. 73, Ben

I've seen this too on a Mint Linux system. It seem to work without a problem on macOS: '' -- Karl Heinz - K5KHK

Hello Hans, Thank you for the quick response.? The reason for my question is that I have a poor antenna set up here and the input level indicator was down below 20db.? I do know it is that antenna

I liked the idea of building my QDX for 9v as I thought the occasional use off a lower voltage battery and still maintain 5W would be nice. Plus 'more efficient' sounded good to me, too, and I also
