Got a faint answer (made out a possible WA2) at my CQ at around 8:00 p.m. DST. Was it you, John? Everything else is QRN and a lot of static crashes.

Hi Allard! Thank you very much for your help! I was ready to post the solution you found and the reason it happened, but you beat me to it. I had the 10 nF cap installed for debouncing and RF bypassin

#firmware #bitx40

Allard, I reverted back to 1.09 (the other version that I downloaded some time ago from github) and I run through calibration. Everything works as it should now. I'll pass on 1.27.7 for now. Thank you

#firmware #bitx40

Forgot to add that I flashed back to version 1.09 and I was able to calibrate and the radio remembers the calibration and the last frequency used. Thank you again,

#firmware #bitx40

Hi Allard! Thank you for the fast response. Yes, I did adjust LSB from 180 ppm to 90 ppm and USB from default to 1310 Have. Also changed the LSB drive level to 2 mA, frequency span to 100 KHz and scan

#firmware #bitx40

After a lont time of using my Bitx40 with Allard's 1.09 firmware I decided today to upgrade to the latest version 1.27.7 No hardware modifications have been implemented except for the Function switch

Jerry, Looking at the data sheet seems to indicate that Ft=360MHz is achievable at 200 mA current. It might not work in our application.

As a complete re-design of the RF low level chain I was thinking of trying BiDiAmps based on MMIC (BGA2851 seems a a good candidate as its price is low) and use BFU550AR for Q90 and 2N2222A for predri

Dana, You do not need any custom declaration. Order your kits from Kees following the instructions in the file section, pay and wait. I ordered in the past from Kees and I have received the goods with

Tim, A short on C62 or R64 will do that. 73,

Just to let everyone know I have uploaded a BOM for the TH version, using Tayda Electronics as supplier. The files are still on my cloud drive: https://app.box.com/s/qf4jubi8942dhwdc8lhivctycnue4f12 D

You can change the value of C7 to 1.0uF. X7R material, 0805 size, there are some nice Kemet with low ESL/ESR (C0805C105K4RACTU). 73, Ion VA3NOI

Here is the link to the files. https://app.box.com/s/qf4jubi8942dhwdc8lhivctycnue4f12 They are on my cloud storage. Let me know if it is not working and I will upload here. 73, Ion VA3NOI

Hi Guys! I have both versions of the board designed. Through hole with a size of 17X38 mm, single side. SMT with a size of 18X31 mm. SMT components are 0805. 1 uF cap is tantalum or niobium polarized.

Not really true. There are lots of people, me included, that put the radio together and started using it. Most of those happy customers are not posting that.

I can hear AC9RZ calling CQ. Cannot get through

I'll try again at 23:00 UTC, maybe the band is getting better. 73!

I am on and calling CQ Bitx for the last half hour but nothing here just North of Toronto.

You should panelize the Gerber's yourself and arrange them in a shape that is not more than 100 x 100 mm. Then you qualify for the special price.

I am expecting that whoever reworks the boars would be paid, which will wipe out the profit/margin anyway. Last I've seen, the transceiver, without Raduino, was $45. I am only asking for the rejected
