I have had 2 of the original volume controls with similar problems. The contact pin rivets had intermittent connections to the resistance substrate. They were going open. I changed to 10K audio taper

Hi Curt, Can you elaborate on the "three relays on a daughter card" fix? I don't need a kit - I'll make my own!

Hi Ramakrishnan, Not sure if your audio problem is related to the audio amp section, but if it is this link shows a fix that shouldn't be too hard to

I also have a 50uV test signal generator at 7040 which I connected to the antenna input. That signal *didn't* sound too distorted when I listened to it. I don't have any other test equipment to poke

Hello, I have been using my uBitx (v4) mostly for receiving until now as I was lacking a good antenna. I observe a couple of problems. 1. Calibration is off by ~1200 Hz (down). I believe that is

That is exactly what I wanted. Very clean install job to boot thank you very much! -- Tim Keller - KE2GKB https://shop.kit-projects.com

Mike I suggest that more, clearer data is needed before recommending a particular spurious fix.? The Axicom relays may work if a board does not require a huge improvement - I think this may be why

Sam, et al I'm sure it still needs something; here's the full 3.5 screen with manual freq entry numbers where they belong and a READ button on the "Mem->VFO" page that should work - Ted

Here is a picture of the completed install of the AGC board on my V5 board if that helps:

Sam, I took the 15 seconds to hook up my S-meter and the display works just fine with booming signals.? There's plenty of travel across the meter. Some of the digits in the frequency manual entry

Thank you for your work, Mike! Your website has been a great resource for me. I'm glad that you have recovered and I hope you continue to do well! Now I know who to call if I need an enforcer.

Thanks Hans for the clarifications. I look forward receiving the QSX! Yesterday I 'sold' a uBitx on the air! It happened that the ham I was talking to (and he was using a Yaesu 9000... ) was so

Mike Take care and thanks for your efforts. Hopefully you are feeling better. Sincerely All of us here

Tena koe Mike. Thanks for all your work. This ex pat Kiwi dreams of the big rainbow trout in the Tongariro and the Waihatanui. Although cousin John tells me that the fishing at Taupo is not like it

The 10W HF Linear PA kit is a module of the QSX and is all through-hole see http://qrp-labs.com/linear The rest of the QSX boards are pre-assembled SMD. However you need to assemble the buttons,

Thanks Mike, hope your feeling better. Joe KD2NFC Sent from Mail for Windows 10 Sent: Monday, March 11, 2019 4:17 AM To: [email protected] Subject: [BITX20] ubitx.net up to date I have finally

I have finally achieved the near impossible and cleared the back log of 2800 emails from the BITX20 list.? All posts of enduring interest between 15 December and today have been turned into news

I would be interested!!!! Suggest add any resistors that need changing also. And caps. Make it a retrofit kit. I retire in 10 months, purchase spectrum analyzer in 6 weeks. Gordon.

Just put a 1K - 10K (any value) in series with the center lead of the volume pot. One of my board used to growl! Raj

Will the new QSX be sold in assembled boards? O have a Genesis 30-20m I have been building since years. Although they have no SMD having a lot of components is a long process to mount, also the check
