I plan to build my Bitx40 with a DPDT toggle switch, so that I can switch between "low" (12v) and "high" (20v-24v) power input to the IRF510 (using a boost converter to get the higher voltage). What I

The Chinese Deek Robot Nano's and the Pro Micro's are cheap and very reliable, I've used dozens of them and never had one fail, as for the displays, everybody copies each other so they basically are

Jack, The best way I found was to make the front from single sided fibreglass PCB. Carefully cut a hole that the LCD will fit through. As close as possible to the outside dimensions of the LCD bezel.

That's two failed Raduinos reported here. ? This one and post 20214: ?"Bad TX audio SOLVED. Not fixed." Makes me wonder if there's an issue, perhaps needs protection from power supply surges, or

I would provide power to the Arduino constantly so it's always running and just have it run a relay or two to turn the power on/off to the rig and lcd display.? You could even put a nc relay on the

Ok - the Raduino arrived a few days ago. Spent a couple of days making a rectangular hole for the display and got the screws to line up. ?Bolted the Raduino to the front panel and powered it on.

Hi Jack My copy arrived yesterday. Haven't started reading yet, but a quick glance, looks to be an excellent book. Thanks Jack. 73 Ken VA3ABN econjack@...> wrote:

Hi Jack and Mike, Fram is just another tool in the tool kit.? I'm paying more attention to longevity these days due to my eye problems, what I'm capable of today I may not be capable of tomorrow.

Congrats on the compile! You called it right when you identified that the sketch was written for the V1.1.2 library. ?Thankfully, it's pretty easy to update the code for V2. Here's the 'read me' info

I'm assuming you powered down and then restarted the rig so the software did a reset. Jack, W8TEE To: [email protected] Sent: Saturday, January 21, 2017 1:06 PM Subject: [BITX20] lost display Hi all

Hi all just lost my display and tuning ?all i got is back light after power lead came disconnected and reconnected any ideas may of blown it ? many thanks for looking gary

Here's a 20x4 bezel I used a while back and was very pleased with: https://www.tindie.com/products/WIDGENEERING/20x4-lcd-bezel-with-clear-backplate/ (

Hi Jack, Yes, I2C is great!? I've used I2C many times before (and in fact have many I2C devices and backpacks on hand - when I was playing a lot I ordered most versions of the Arduino, LCD displays,

That sounds great Ken , look forward to seeing the results
