I really like this post.? There was a time when I used CW while driving. It was long before texting and driving was illegal or even possible. I guess I was a cutting edge rule breaker :) That was

Nice work Greg. can you clarify one point. Did you make any circuit changes to incorporate the optical encoder? I was planning to use an optical encoder (5 v) driving the bases of two additional npn

Hi Hans, thanks for the reply. The voltage does change between 0v ( display fully of blocks) up to 5v ( display blank). At no point can I see any text on the display. I took the measurement from the

DVCC is the power input for the digital circuits on the AVR. It's actually labeled VCC on the pinout diagram. Quoting from Hans: "I believe Peter's comments and suggestion make a lot of sense. In

Hi Simon I think you should check the contrast setting. Maybe there is a short or other fault. As you adjust the contrast potentiometer, can you see the voltage at the LCD's contrast pin change,

Thanks Marc, Im beginning to think it might be the IC2 at fault? With no chip installed I get just the top line of blocks. Two lines of blocks with the chip in.

After 22 days and about 12h the flight came to an end, it ended up in a bad weather system and descended. It traveled +51000km and made it 1.5 laps around the world, here is the flight path:??BSS12

I expect it’s a Bourne PEC11R series encoder. Mouse or DIGIKEY if you are in North America. Dave VE7HR Sent from my iPad

Hi Ken I think this is the encoder........ http://www.ebay.co.uk/itm/Rotary-Encoder-5-pin-Top-Clickable-Switch-Arduino-Raspi-LinuxCNC-PIC-AVR-UK/261857741214?hash=item3cf7f0099e:g:jlsAAOSwPhdVM6Wa (

Looks like a great solution Greg. Looks like Hans better stock up on the case as I for one will be copying this solution. Thanks for the post. 73 James 2E0MUA.

A forum post on eHam CW forum about QCX for those that want to contribute to it is here ( http://www.eham.net/ehamforum/smf/index.php/topic,117417.msg1029870.html#msg1029870 ) and mentions likely

Apologies if this has already been covered, but one of the mods Hans recommended for the QCX was to fit a Schottky diode from processor AVCC to DVCC to prevent any startup issues. I have identified

Yeah, it was, I turned it down but still I have no power out on the wattmeter. I did something wrong but just dont know what.

Your bias is probably set too high and it's self oscillating

Also, this might help someone help me more, the BS170 is hot or very warm to touch even when not in transmit.

I've read page 3 and 4 of the manual a few times and I still haven't figured out how to make the clock display scroll through the data I put in line #3 and line #4. I have figured out how to screw up

Simon I wish you the best with the display. Marc

Hi Jim Which firmware version do you have? There was a significant improvement in Tx/Rx noise after the initial firmware version. I'm surprised you have a big click. On all my versions here I operated
