Crud.? There's an M1/M2 flag on the T/R relay, K3, as well as the M1-M4 flags to ground on the top of schematic.? I guess that's how the signal jumps the M1 to M2 flags.??Sorry for the noise,

It looks to me like it was intended to be assembled thus: 1) Enlarge the hole in the heat sink to accomodate the bushing. 2) Insert the screw in the bushing, and the bushing in the BACK of the heat

Hi Don, I appreciate the walk through!? Ultimately, I'm finding that I'm unable to trace the audio signal because it appears to go to flag M1, while the input for the final amp seems to have to come

Andy, Perhaps you're thinking of the MOSFET as being like a vacuum tube (Fleming valve) and requiring a bias voltage at the drain (corresponding to a tube plate). It does not. Consider the device to

So I got the ceramic insulators.? The included bushing fits the screw just fine.? And the screw, without the bushing fits the wafer just fine. But put the bushing on the screw, and ain't nothing

Put another way, maybe:? I can't figure out how the audio signal makes the trip from the audio pre-amp to the LM386 final amp.

I can't speak to the rest from the vantage point of my modded V3, but it appears that item 1 has been and/or is being worked.? Ashhar reported it on Christmas day, 2019.

Charlie Hello again. I finally got back on this project and am a bit puzzled as to which board stack on the headers. I ordered the adafruit proto board and it can be stacked with the nano or with the

Reed, for fast tune I was referring to the fast tune mode when selecting VFO twice. The accelerated tuning feature is also ?very nice. At very slow speeds more precise tuning is possible, as you

I'm trying to understand the flow of the signal through the audio amp and pop-fix FET (Q74 in at least the V6).? I *think* I get that in the amplifier stage around Q70 (V6) has a bypass cap to

Thanks Reed I have ordered in a new pencil iron with variable heat control and a number of varied selection of tips so won't be at this for a bit I want to add the extra morse jack for a straight key

Thomas all OK here tnx

Hi Mick, 4) When you say "fast tune" do you mean the "fast tune"mode when the VFO is selected twice, or the rapid acceleration you get when spinning the knob quickly? 5) The font is slightly smaller

I didn't actually make it run time configurable. Only compile time. Perhaps I should add a configurable setting for it... Definitely something I'll consider. Reed

Your health definitely takes priority over radio shenanigans. I wish you a speedy recovery! Reed

Reed, I loaded the hex file (thanks for providing it). Some comments 1) Very Nice!! 2) I like the setup routine, freq adjust resolution, and BFO save not exiting the program makes tuning much easier.

Hi Reed, I have it uploaded and will be testing today. So far it seems to be working great, not to much acceleration but enough to get you across the band. I will report any anomalys. Joel N6ALT

Reed: At one time I had written a short article for Doug Henrick's QRPp magazine for what I called "Fast Tune" that worked in the same manner using a timing interrupt. You're right, the rate is very
