Re: Forty-9er Transmitter
Thanks, Jack. For the CW CapSenseKeyer code I see PADDLECOMMON set to 4 but do not see that PB4 is wired. Please explain. No rush. I work 8 hours a day too. Bob KF6ABC MIx

Re: Forty-9er Transmitter
I'm no EE guy, but if the receiver is working, that tells me that the VFO is working. I think you should see about 2-4Vpp on J2 or J3. I've asked Dennis to look into this further, as it may be well

Forty-9er Transmitter
My receiver works, but the transmitter just sends a clicking sound. What VPP should I see on J6 from J3? What is the procedure for tracing this problem? Bob KF6ABC Mix

KY-040 encoder threaded for mounting?
I have ordered and received a couple of KY-040 encoders expecting to get the ones that are threaded to take a nut and getting ones that are unthreaded. The vendors have been nice about refunding money

Re: CW Automatic Keyer
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:

Re: CW Automatic Keyer
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,

CW Automatic Keyer
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

How about a Contest in September-Pefect for this 49-er/VFO project?
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

Re: VFO Encoder Tuning Stops
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

Re: VFO Encoder Tuning Stops
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

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
