My apologies for the bandwidth, I've now found the information I sought.

I've delved into the backlog of posts and found myself unable to ascertain whether there are any pcbs to be had.?
Very interested in acquiring 2 or 3.
Cheers
Ross

Just a reminder!

Hi,
I've just released raduino v1.27, download it from

New in this release:

• Improved the suppression of the spurious carrier when switching from RX to TX.
• The default TX-DELAY is now 65 ms (you can adjust the delay time by editing line 71 as necessary)

IMPORTANT: This sketch version requires the library "PinChangeInterrupt" for interrupt handling.
This is a non-standard library - it may not yet be installed on your system. However installing it is very easy:

1. In your IDE, go to Sketch => Include Library => Manage Libraries...
2. The Library Manager will be opened, wait a few moments for your IDE to refresh the list of installed libraries.
3. Then, in the search box (Filter your search), enter "PinChangeInterrupt"
4. Select the library PinChangeInterrupt by NicoHood and press the Install button
5. You can close the Library Manager when the installation is completed.

Then compile and upload the sketch as usual.

Happy BitX-ing!

Good Evening!

What is the nomenclature on the Q13—need to try that replacement to see if the power picks up...only ~100mw now, if that.

A new net devoted to Makers (DIYers, homebuilders) has started up on Echolink conference node 9229 (*TECHLINK*).? All those interested in building their own “stuff” are invited.? The net is on Sunday and starts at 21:00 UTC (4:00 P.M. EST, 1:00 P.M. PST).? The net was established by Michael Beaveridge, VE7KI.? See website at .? All aspects of building and programming related to ham radio are open for discussion.? Please drop in.

Mike thanks..
Did that (on the way to the speaker...will have to get it so that if you plug the headphones in it will filter that too..
haven't tried that yet..
works great..
Dayton purchase 10.00...
thought it was worth it.

This is my answer to the usb cable extension.?

I'm not sure about the website. I've never heard him mention one. Jack is very active in this group, and the board was shipped quickly after I ordered it through PayPal.

It is a fun project - Just so you know, the components for the board cost me $84.68 from various eBay and Aliexpress resellers. The most expensive was the TFT display at $18.28 and then the Mega2560 Pro Mini at $18.00 (there are cheaper ones on Aliexpress but the documentation says they are the wrong size and wont fit into the pc-board).
The DDS board (AD9850 Type II) was $12.98. The rest of the items were each under $10.00 each.

Have fun!

Does Jack have a website for this or is it all just through email?

I am interested too. ?Looks like a fun project.?

Hi All
I am very new to the group and the BITX40 and have been looking at the mods and other enhancement.
Are the W8TEE TFT/VFO and AGC, CW and speech proc, still available and if so where do I get them.

Thanks

After some code investigation, I discovered that the RTC does not use an interrupt, the clock is polled and updated every time though the Arduino loop which turns out to be between 4 - 6 per second with debugging turned on (it's probably more often with debugging turned off).

I added some code that only updates the RTC only once per second (or very close to once per second) and that seemed to help out the responsiveness of the rotary encoder although if I kept turning the knob, the frequency display would miss a few increments because the Arduino was updating the clock. Perhaps Jack will have some suggestions when he returns from vacation.

I had to look that one up...

This is a narrow audio filter, (probably) centered around 750Hz, and a (switchable, down to a) VERY narrow 80Hz bandwidth.

You would place this at your BitX Audio output, and before the speaker / phones.

Sorry for my weak memory I actually installed a "down angle mini 5 pin USB to USB 2.0 B female panel mount" it is 50 cm long so you can mount it any where on the back of your BitX.

You could also use a "right" but if space is tight, the down takes up less space.

73 Willy??

Hello.
Thank you John and Willy.
I just ordered one from willy's Ebay link. And since it's the same female connector as my SDRplay RSP2, it's even more convenient.
Thank you and have a good day.

Needed to remove the 10 turn pot to install it but that was better than having to drill new holes? or remove the pot for each new sketch.

I actually had to remount the 10 turn pot on a bracket and use a shaft extender on it when I added the right angle USB connector. For those in the process of building, plan ahead a little and you can probably make this addition a bit easier on yourself.
