Hi Doug, How did you scale? In Cura? I went through all menues but cannot find any such opportunity. I would love to learn how! Bjorn.

I wish there was a good drawing program that was reasonable to learn! What a learning curve. I can make the knob shorter (less depth) real easy, let me know what you want? It is just changing an

OK Pavel, noted the change of polarity of diodes. 73 Carlos CX8ABF Sent: Friday, June 23, 2017 1:17 PM To: [email protected] Subject: Re: [BITX20] Like to test a S-meter and soon an AGC/Tx-monitor

Hi EA3IAV, The wires from the antenna output to the antenna connector (BNC/PL-259/etc) must be as short as possible to avoid RF radiation inside the Bitx40 cabinet. The "dial is locked" when in TX

Check it again, I have updated the code... 73, Pavel CO7WT.

Pavel, I think your approach is best for use on the Bitx40, leave the output dividers in integer mode, adjust the VCO to change the operating frequency. ?We don't need three outputs. ?If we were to

Hi Jerry, read inline. I'm working with Allard to make a folk of it with the exact interface of the mainstream Si5351 that is in use now, to make them interchangeable by just changing the

Allard thanks for the suggestion, unfortunately I have run out of debugging time until Sunday as I am headed out of town. ? It occurred to be that if I disconnect the TX-RX mod from the PTT jack,

with the diodes in the describes position the oputput voltage would be negative instead of powitive-- so reverse both diodes! Henning Am 23.06.2017 um 18:15 schrieb Pavel Milanes Costa:

WARNING !!! Diodes are backward in this picture! The original picture was corrected by now in the github repository. Sorry by the mistake, Pavel.

Michael, please verify the transistor connections. Switching emitter and collector causes exactly the behaviour you describe: Once the transistor is opened it will remain open forever until power

here try this? its easy and works great https://www.thingiverse.com/apps/customizer/run?thing_id=54024

Mike, I printed the VFO knob in PLA and it fits great.? Thanks for drawing it.? I haven't progressed past tinkercad.com for designing. Bjorn, I use Cura too.? I just scaled the object by 25.4 to

I just finished the CW mods and I am seeing the same issue that John, WA2FZW had. ? 1) When the press PTT in LSB mode the Rig goes into TX and I am getting full power out on voice peaks but the PTT

Thanks Jerry, great bits of info! Ok, I have some IRF510's at hand but want to try the 840 since I can source them locally, also plan to abuse 'em a bit to see how much power I can get from those.

hi all i am looking at building a ubitx from scratch but two problems. where can i buy a set of matched crystals for the filter what is the details of the transformers terry gm4dso

hi royal mail seems to have taken a hint from dhl. i received a parcel from my daughter in new zealand and was charged. terry gm4dso

Sorry I misread your email! If Q7 is dead then you could wire a 2222 or similar and it will work.

See R74 is open. Happened to me !! If Q7 is hot then R72 is open. Let us know. Raj

Hi Raj, Jerry, I'm glad I listened to you guys and didn't take out the diodes. Jerry, you were right about the VFO. ?My friends board had a nice sine wave at the output of Q7 but mine did not even
