Did you try the knob customizer, or just ones that had already been designed?

Very nice! I really like the plastic cover over the display. I might do that myself! When cutting small pieces of plexiglass or lexan, I remove the protective covering that comes on it and use masking tape in its place. I have a jigsaw and if I clamp a guide to the table and use a fairly slow speed, I get pretty nice straight cuts.

Hi,
To cut the window I drilled holes at the corners then used a scroll saw. I finished by hand filing.
It was not easy to get straight lines! I did the marking up and the first drilling on the back of the front face. Then completed drilling the holes from the front toget clean cuts.
Regards, John

Looks fantastic?
how did you cut the window forvthe lcd?
a little bit if weight is wanted so you drag the rig while taking your mic

I moved my Bitx to a smaller aluminium case. It¡¯s very strong and compact, but now the Bitx weights about 1 kilo!
The box is extruded aluminium from Aliexpress - 145*54*200 mm. Cost about $US16?
Careful measurements were needed to pack everything on the front panel. Holes drilled using mostly step drills. RF and AF gain on front with 10-turn tuning. Two buttons - room for more. Just function at the moment.
On rear panel: On/off slide switch plus Hi/Lo power slide switch. Inputs for 12v and 22v. Headphone jack. Big jack is for CW key - not wired yet. Voltage regulator on back panel with reverse/overload protection. Space at rear to fit AGC board and/or SWR/power board.
Small holes in the sides for cooling, air can exit around the speaker and through the grill on top.
I¡¯m using Allard¡¯s latest Raduino (Thanks Allard!).
Best 73s all,
John VK2VOL

Hmm...Is there a Roomba in somebody's future? Hi.
Maybe you can program it to go fetch lost smd parts...
Incidentally, programming the ATMega32U4 is not exactly for the faint-in-heart;
It is like the Leonardo, with an integrated USB interface, but less memory space
than even a UNO. Prepare to meet your challenge, maker! ;)

Re: Testing a new board PA
Could be due to any or many of the following reasons:
1: Low audio drive - very likely (I use an amped Motorola mic and it goes up to 10W)
2: Low VFO or BFO levels
3: BFO frequency may need tweaking to suit the filter or your voice.
4: Low BiDi amp stage gain - unlikely
5: Low gain in final RF amp stages - short out R131 and see
Considering you get 5W it is not really low as you think!
Cheers
Raj

My original BITX never "aligned" correctly. In order to get the 1 amp current draw when hallooo'ing into the mic I had to crank R136 all the way. In that way I could get 5 watts out but only if running higher PA voltages.

Re: Testing a new board PA
Jonathan, radios amplify and modulate radio frequency (RF) signals, that RF signal is generated by the local oscillator (LO) in this case a synthesized VFO. Without it you don't have anything to modulate or amplify, no RF, no radio. This doesn't work like an audio amplifier to see your voice output from the PA. I hope this help you understand why that test didn't worked. 73! Dan. On Mon, Jun 19, 2017 at 10:50 PM, Jonathan Peakall <jpeakall@...> wrote: Thanks!

I got a second board and was playing with it yesterday. I wanted to see
if it behaved differently. So I hooked up the PWR, PA PWR and a mic. I get
about 127mA at idle but no increase when I halloo. Does the VFO need to be
connected? I'm guessing so but just thought I'd ask. That takes a little
more doing and I was just curious.

Just to close the loop I ended up buying this:
I never would have thought of Walmart but thanks to google I ended up finding it there for $21.95 with free shipping.
Not BITX related but I built this kit tonight ? my wife heard me say blah blah blah solder blah blah blah arduino so she got it for me.? Now I really need to learn to program arduinos.? Back to the fume filter, it was much better than nothing but not from perfect.? Thanks for the suggestions.
