In case that was the cause, I replaced the D882 with a BD139 from W8DIZ. Same problem. Bob

Several others have had that problem. I've dialed my voltage back from my base rig voltage of 13.8V to 12V and I've not had any problems. I did have a heat sink on it before that, but have since

I had the same thing happen to one of the 49-er kits that I built and another one from a friend--it was a blown D882 transistor in both cases.? de Karl, KO8S

Ok, but there are several files in that download. Which file are you looking at? Jack, W8TEE To: SoftwareControlledHamRadio@... Sent: Thursday, August 18, 2016 3:28 PM Subject: Re:

Here's 10 encoders for less than $5 including shipping (search: 121993737161): Of course, these are from China, so you'd have to wait a while. Jack, W8TEE To:

I also needed an encoder with threads, and was concerned by several comments from buyers who were disappointed to find out that what they got didn't look like the pictures. I picked up some from this

Hi Dave, Send me you address and I'll send you one.

What source code file are you looking at? I don't remember writing code with PADDLECOMMON in it, but that doesn't mean I didn't...I've probably slept since it was written. Jack, W8TEE To:

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

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

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

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

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
