Greetings I really like the N9ME software for CW. ?Usability is greatly enhanced by adding a filter. ?I've put the Hi-Per-Mite in mine. My CW upgrades are described here

Every radio I have ever looked at used one heatsink for the amp. The 50 watt FET amp that won the QST challenge did too. I’m not planning on pulling the fets off the board and mounting it far

Raj, the MDS at 7MHZ is 10uv. A 50uv signal is as loud as the mixer noise. Barry Sent from Mail for Windows Sent: Sunday, September 4, 2022 12:51 AM To: [email protected] Subject: Re: [BITX20] Daylight

Thanks, fellows. ?I'm probably going to set aside the Nextion for now as I'm very happy with the N8ME sketch for CW. ?Maybe later this fall or winter I'll try the Nextion again. 73 Howard K4LXY

Hi Howard, Sorry for the delayed reply, hopefully others have already solved your problem. I am using Arduino IDE version 1.8.5. I have not tried more recent versions. Under the IDE “Tools” tab I

Hello see here: [email protected] | Help programming Arduino ( /g/BITX20/topic/90507972#92948 ) see answer of Gary Try a old version 1.8.12 cdt

Barry, I do not see one thing at all that is "shoddy" on your boards. I can even make sense of it while looking at what is going where after a bit. (Try that on any multilayered trace board made

I've used these active USB 2.0 extension cables with clip on ferrites attached to each end before to mitigate RFI between my PC and a RTL-SDR dongle. https://a.co/d/eZFPMR1 I wonder if this may be a

The original on LTSpice turned up with a 10KHz roll off which is too high. So changed values with suggestions from Farhan till it looked right at 3-4KHz. This should reduce high freq whines and hiss.

Steve, If I was 10% as brilliant as Dave (W1HKJ) who wrote the fldigi, I would have gotten the psk31 decoder right on my own. Dave and his band of merrymen and a league in themselves! - f

Farhan - Hi Hi - and I've been telling my friend how brilliant you are to have used FLDIGI to decode CW, and RTTY. FLDIGI has a bunch of other digital modes that make the sbitx more capable and

The CW is a strange implementatoon. CW sending is done internally by sbitx but it passes the audio to fldigi for decoding. In the future, I would like to move all the modems directly into sbitx and

Reminder that if the sbitx is not properly shut down, the sd card can get corrupted, Shut down the Pi using the Logout option in the menu, then selecting shutdown. Wait 20 - 30 seconds after the

FLDIGI CW decoding seems to work best when the red 'pitch" line is just a little bit to the left of the peak in the spectrum display. Look at the scope display in FLDIGI and you can see when it's

The desktop icon is created by copying a file with .desktop extension in the folder/home/pi/Desktop. That file is already in the /home/pi/sbitx folder. 1. Press ctrl-alt-T to open the terminal. 2.

Please let us know how that works out. I've wanted to do the same thing to mine. Max

Wasn't there some sort of problem doing that? Capacitance between the heat sink and the IFR510 maybe? I vaguely remember some sort of issue doing that. Max

Can both IRF 510s be mounted to one heatsink if mica insulators are used? I’m thinking about doing a separate 24v supply to the finals. John N4HNO

The red line on the spectrum display is controlled with the pitch control. That marks the cw/rtty/psk31 decoder's central frequency.

Dear Ashhar, I was able to scale the part to 110% of the stl file you send me and the nuts fit perfectly.? CURA will allow you to scale the part before you slice it.?? So, it took a couple of tries
