Did you download the book's code from the M-H web site? I'm not at home right now so I don't have access to my system, but the URL is given in the book's Preface. Jack, W8TEE To:

Physical pins 5 & 7 are software pins 0 and 2. Where can I download the latest code? Thanks, Jack. Bob

It's been a while since I've looked at the code, but Figure 7-14 shows the cap sensors on pins 5 and 7. I'd go back to the book and read the section on the cap sensors starting on page 144. Jack,

My ATTiny85 runs the Blink example to flash an LED across pins 4 and 5. But the Keyer code does not work for me to detect capacitance on pins 0 and 2 in the keyer circuit. I changed OUTPUTPIN from 4

I would guess by September of this year, most of the 49-er/VFO radios that were built from March QST of this year, would be on the air by now, or will be very shortly, and will be ready for their

Absolutely! I've often said I have enough EE knowledge to be dangerous. I know all three of us are tickled by the number of people who have taken the time to build the Forty-9er. For those who don't

Jack, You nailed it!? This is such a great group, with really great members.? I also want to express my thanks to the group for receiving the QST Cover Plaque.? I appreciate YOUR comments about my

Thanks for the email...it's sincerely appreciated. I should also thank a bunch of other readers, as the QST article won the Cover Plaque Award for the best article in that issue. It's a nice repro of

Thanks Jack!? Boy, this is a lot of "kool" stuff you are doing!? I sent a letter via email,?just now,?to ARRL,?praising your 49-er/VFO article and this forum!? Let's see if it makes the pages of

On the inexpensive KY-040 encoder, the power and ground leads are clearly marked and the center lead is to the switch. The two remaining pins are the clock and data leads. Just reverse those.? BTW, I

Me too!? I could not have done it without them!? de Karl, KO8S

Hello Dave; In reading your post on reversing the leads of the encoder to reverse tuning; which leads would I reverse to accomplish this seeing that there are 5 of them? Thanks, Karl, KO8S

I like the way this group helps one another...good stuff! 73,Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Wednesday, August 10, 2016 11:42 PM Subject: Re:

Hi Bobbie: It really is surprising how well the rig works, given its cost. I did manage to smoke a final transistor during a "key down" test, but I was running 13.8V from my large xcvr supply. I made

Thanks Jack I replaced the nano and DDS boards from the working unit to the non-working unit, and still does not work.. I checked the transistors with an on-board transistor tester and it shows two

Hi Jim I would like to hve the scope.. how to contact you directly? bobbie kd4lv bob4john@windstream dot net

Karl, I put a very small series resistor in the D882 emitter leg to calm it down. Still getting 2.5wts out into the dummy load. I also put a good chunk of aluminium for a heat sink on the D882s

Thanks Jim for the encouraging words!? Until the 49-er/VFO article appeared in QST, I had never heard of a "sketch" either!? I had heard of the Arduino, but I just assumed that this was some kind of

Hi Jack, No, 200-300mV p-p is the data sheet specified input signal amlitude pin 6 of the NE612 wants to see from the external VFO, in this case, the Nano DDS VFO output. Afterall, the output of the
