Tom, this is a regular Sunday evening event.?

I hope there will be others or maybe a regular thing, as I have not put my bits together yet.?

Q13 is an mmbt3904. ?
It runs hot, a 2n3904 would be a better choice if replacing it as the leaded version can dissipate more heat.

But there's a hundred different parts that might reduce power on you like that,
you won't do much good just shotgunning every part in the transmit path.
I suggest you check all the DC values around Q13, and not rip that transistor off the board
unless the base and emitter voltages look wrong when pressing the PTT switch:

Here's another thread on debugging the transmitter.: ?

I have a 3D printed Bezel as addition to the RaduinoX "better" Raduino.

It comes with some Flat Head metric screws, and additional plastic standoffs and screws.

There all also spacers to hold it squarely behind the front panel.

It fits the standard 1602 LCDS.?? I sold a half dozen to members of this group.

$3 if shipped with RaduinoX, $5 if by its self.

I've had an hour browsing the old posts looking for a source for a trim panel to go around the standard bitx40v3 display.
No luck finding anything. Does anyone have source for such an item? They seem to available from photos in the photos section.
A UK source would be ideal.

Cheers, Richard.

I have one left from the VK group purchase, Ross. $15.60 including postage anywhere in Oz.

Bill, VK7MX

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

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.
