All compiles fine under 1.8.9... the updated libs in 1.8.13 seem to cause bloating...

What version of Arduino are people using to compile this ?
Thanks!

Dale,
Correct save for NOS abounds and also poor quality copies.
Its more be wary and careful.

Bob,
Mounting from the back side was only part of a complete mod.? Do only partial
and you get poor result.? Basically for that iteration a half fast fix was not a fix at all.
See the wiki for the fix and wiring plus the code patch to take advantage of it.
Also if you burnt the tracks off that give you head start.
If you still burning off tracks investigate a better tool and or soldering skills.
The Mod I wrote up for V3.?
By V4,? V5, and 6 it was incorporated into the board layout.? We have a Wiki
here for history and knowledge.

Tried to compile this on 1.8.13 and....
"C:\\Program Files (x86)\\Arduino\\hardware\\tools\\avr/bin/avr-size" -A "d:\\tmp\\arduino_build_194091/ubitxv6.ino.elf"
Sketch uses 30754 bytes (100%) of program storage space. Maximum is 30720 bytes.text section exceeds available space in board
?
Global variables use 819 bytes (39%) of dynamic memory, leaving 1229 bytes for local variables. Maximum is 2048 bytes.
.... so close and yet so far. Any ideas for shaving off a few bytes ?
Thx!

I suggested mounting the relays on the opposite of the board's ground plane as you say back in the days of the V4 and I remember someone trying it. The results from him was it provided no great improvement as far as meeting FCC requirements, at that time.
Please let us know if this does provide an improvement since the board for the V3 and the V4 may not be exactly the same.
This would also mean making sure the four corners of the board are mounted to a metal box, for example, to make sure the ground plane is indeed at an effective ground for the RF signals and possibly ensure a better overall ground.

Hi Ken,
I did Alison's changes for the relays on my v3.? It might work well for you, as with the relays mounted on the bottom side, their pins all end up on the top side where most of the traces are.? I can upload pictures of my board if you want.? The work will require changes to the raduino code afterwards.

Hi Allison, While that is still true of type N, ?75 Ohm BNC¡¯s changed over to the same ?diameter center pin as the? 50 Ohm version some time ago. In order to maintain 75 Ohms, the dielectric is configured differently. ? Dale W4OP ?

They have different plastic sizing and the center pin and socket are differently
sized.
Same issue for the oddball but occasional 75 ohm type N.

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
Ali express you can buy it.
Does anyone know of a source for these?
I used to buy these from Oak Hills Research, however with Marshal Em's passing you can not order from OHR.
It is just a plate with 4 screw holes spaced to match an SO-239 bulkhead fitting and a d-hole in the middle to fit a BNC bulkhead.
There are other ways to handle this conversion but boy does that little plate make it easy.

Which is the latest version

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
Some may not be aware that if you remove the locking ring from a BNC male connector, it will plug into an N connector. Shops sometimes make quick-connect jumpers this way.

Tim, I see your kit for uBitX! It looks like I can install it on my v5; not too hard. ?Do I understand correctly that it can be wired to drive the SMeter In the faceplate of my inkits case? If so are instructions included for that?

Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
Hi Dave, There are a bunch of off shore connectors out there that are just a mess. If you stick with named connectors- Amphenol, Connex etc, the center pin spreading is not an? issue. I also use nothing but teflon dielectric on all of? my connectors. ? Dale W4OP ?

This picture with ports labeled might be of use in the future.

To be clear, do you have a uBITX version 6 with the touch screen or a BITX20 which was a single band 20-meter radio?? It does make a huge differance.? The model should be printed on the mainboard.
IF you have the uBITX version 6, then the firmware files are here:
I do not know the current version for the BITX 20, nor where it is kept.
