Hi Ryan, "Switch sidebands without inverting the VFO to 19mhz" Raduino v2 for BitX40 already has exactly this functionality, perhaps you could use

Hello Everyone, I've been working on my own digital VFO/BFO for my BITX40. The goal: Switch sidebands without inverting the VFO to 19mhz for 40M and 26mhz for 20M. I've got it working, mostly, but

Hello All Many thanks for all the interesting answers to my questions at the beginning of this topic! Having thought of starting such a lengthy conversation. One can learn a lot, but I must admit,

Hello Ian Made some test transmissions with the new version and, as you can see on wsprnet.org, the signals are heard all around from the uBitx on a 42m vertical delta loop. All settings left as per

On thr hfsigs site, or anything else that I endorse or recommend, I never do that without having tried it myself. That is the unfortunate part of pursuing experimental methods. It is also good in that

Incidentally, I did edit "amaxzing" properly. Hmmm...maybe there is a bug somewhere. At least it isn't all my old brain. Hi. john AD5YE

What is being proposed here is a bit like a proposal to herd cats. I suppose it could be done, but is probably more work than it is worth. It is common to just about all human endeavors that are worth

Nick, yes *the pin-out is different* so you need to twist it around a bit. Easy done.

Your site is the Best, Thanks. It takes a lot of work to keep a website up to date. Keep Going! Mike, WA6ISP

Thanks for the tips Jerry. Will recheck Q90 again and also R81.? 73, Guy

Here is RV1 in the circuit: [image1.png] It’s between two stages in the transmitter amplification series of 4 stages.

RV1 is used to set the drive level. M

Nick... no need to upgrade those T30s. Remember they only have to dissipate the harmonic power not the primary. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner -

THANKS FOR THE INFO MIKE. NOW CAN YOU TELL ME WHAT RV1 DOES? I KNOW RV2 AND RV3 ADJUST THE PA CURENT.

Nice work Glen. I am still to solve my oscillation issue on 20m+, but I have also decided to upgrade the LPF toroids to T50-6, I am concerned that the T30 will be overwhelmed at 20W output... Maybe

Obviously I would be happy to curate an Errata page.? However, it may be better to have this on the HF Signals website in terms of giving confidence to new constructors. I would be happy to curate

I was able to reproduce this. If after downloading the zip file from github I assume you just double clicked the downloaded zip file and opened ubitx_20.ino by double clicking it too. Windows just

We often have the related problem of sidetracking a perfectly good thread title For example, we might have a thread going with "uBitx:? loud spurious audio tones" and somebody pipes up with a new

Hi John, no not yet. Plan is do that asap, duplicate the final stage with RD16HHF1's and hook up to my driver section.. Depending on how it all works of course, then mod my uBITX. glenn

Bob GM4CID placed a comment on my article“Ubitx modders are hard at work” <http://ubitx.net/2018/03/11/ubitx-modders-are-hard-at-work/>? about another very interesting Raduino solution from
