I agree, Toroids.info doesn't lie! ?So is there some inductance amplifying affect from the other two parallel windings? ?Can anyone else with a spare 8:8:8 transformer lying around do a reading?

Thanks for all the info. I emailed the guys at HFsigs and they say if I don’t get it by Monday, they’ll re-ship. Alan K6ZY

It also wouldn't work. ?If the knob is hard left or hard right, then we scan down or up by 10khz continuously once every 200ms, even if the knob stays put.

There's plenty of changes that need to be made to the Raduino sketch. ?But those are not changes I'd find compelling: Tuning position within the current 50khz range at power up may as well be

Jack, FYI - yesterday I ordered 2 x boards, and today they are listed as shipped, so they must have stock again. I’ll keep you posted on progress. thanks Darryl

Hi Jack, Thanks for being a frequent and sage member of this group. I am very much interested in a AGC, CW, and "S" meter solution for my Bitx40 XCVR. I really hate ugly construction and

Hi there, Wound six 8:8:8 trifilar transformers on FT37-43 toroids yesterday. On the LC meter each winding measures in the range 38 to 41 uH. ?Can anyone confirm that this is about as

Hey KK6ISP de WA6ISP! Nice Call Sign WV6ISP in 1959! Mike, Yucaipa

Thank you for your comments. I'm still getting my head around exactly how doTuning works. As I don't yet have a functioning Raduino, the following is based on desk checking the code. I may be able to

Wow! Just Wow! Going to MAKE me one of those with my Raduinio!!! 73 de ZL1NC

Hi, ? Already own both of these. Anyone know where I can find the code and tips for using them with the Bitx40? ? -B

Here's your clue: ? ?Search for ? ?brown + red + calibrate Here's the story: ?The "Calibrating The Raduino" section ?at the bottom of?http://www.hfsigs.com/bitx40v3_wireup.html (

Clark Martin KK6ISP Correct. Do you mean twisting the wires. It reduces signal coupling, IE RF getting into the audio via the pot leads for example.

Mike No sales tax here in Or. I ordered the 5 pac. Thanks, Randy, K7AGE

The Beta I refer to below is for the B40 rig, as I'm using an AD9850 and a TFT display. The AA code for the QRPGuys PCB is stable. Jack, W8TEE To: [email protected] Sent: Wednesday, March 15, 2017
