From post 35235:? "The displayed frequency should be exactly ? sig = clk2-(clk1-clk0)" Looks like the github code causes the calibration to jump in steps of 10ppm, which means clk0,1,2 all jump by

Glenn, Nice PCB layouts! Digging your projects as pictured on QRZ... Do you have schematics/etc posted anywhere? Love seeing other's homebrew stuff. For now linear SWR-only tuning works, but

QRZ has changed their link policy so you’ll have to type in my call sign for now. Dave WI6R

Happy New Year to all. Received mine on the 24th (lucky I ordered on the 10th). Got my case yesterday late afternoon and finished the case prep before turning in. Wired up this morning. It’s

I just ordered mine tonight so time to wait for it to come chris

Bill-interested in a kit and could do some building also. Andy KM4TRT

My Control board takes a plug IN NANO baord and caters for a few different display type from parallel LCD's to I2C devices. It has provision for LED's to indicate which relay combination of L&C is

Hi Bill, thanks for the warm welcome. I used the AD8307's because they work much better at lower power levels. And off ebay they are extremely cheap. The project already has two relays for switching

Same here 12/23 date. Pretty excited!? Thank you, Farhan! Tom AB7WT

Glenn. Welcome aboard and hope to work with you more… Yes I see you have been working at this project for a while now. You have developed some very nice boards. I’ve used the AD8307 on a lot of

K3NG provides a good starting point. But I found a few flaws in the algorithm that he uses, at least so I think. Here is the comment I put in my code for my ATU, and my thoughts. Warning: Long read

My pleasure!? I remembered reading it but couldn't immediately find it when I 'needed' it.? (Story of my life.? LOL)? Thanks for blazing this trail - I look forward to getting my rig on the air

?Don't know an exact number,mayber 2.2-2.5 kHz. much wider than the bitx40 I think. ________________________________ Sent: Sunday, December 31, 2017 6:02 PM To: [email protected] Subject: [BITX20]

Hi all do we know the band width of the bitx40 v3 ,and is it possible to alter, rgds John 2e0eii

My 1st post. Have a look at the K3NG ATU (Google K3NG TUNER). While he designed it as a balanced tuner, I have built an unbalanced version for around 20W or so. Using standard footprint 'cheap'

I am available as a Beta tester as well. v/r Fred W4JLE Sent: Sunday, December 31, 2017 15:43 To: [email protected] Subject: Re: [BITX20] Tuner? Well Sure! I am willing to beta test. Paul K0ZYV _____

I have been following this thread with interest ... I think latching relays are the way to go, but certainly cost is also important and higher amperage latching relays are not so cheap. I have been

Ah, you're designing for 100W and some pretty low impedances. I'm not designing for that much power / mismatch I guess :) 10ohms, 50W, which is close enough for me and can still tune an SWR of 5:1,

Nice looking case. Please spell check " transceiver".Just a small correction.:)
