There are ideas that sound good in the abstract, but quickly fall apart as they are brought into reality - I suspect this is such an idea. That being said, aren't Elecraft radios 'somewhat' modular?

To commercial interests, incompatibility is often a marketing lock-in ploy. Fought for 10Base-T lost to Token Ring... James

Andy, That sounds good, and my sincere congratulations on solving your issue. Welcome to the forum! Some of us did have a bit of fun with the direction you took with your original post as a way of

I received my uBitx in February but did not put it together until early May. As soon as I plugged in a mono headphone I blew out the TDA2822. It did have the WX on it. I removed the chip and installed

Arv: My EE knowledge is like going to an axe fight with a squirt gun. Perhaps the best I can hope for realistically is a modular approach. Separating into function blocks like we see in equipment

A PA board up against an exciter is a recipe for trouble. Potentially has 40 dBm signals very near some -20 dBm signals. Digital stuff near the exciter could also cause trouble. Could be dealt with by

Thanks Hans, I read now ' The double-tuned circuit with transformer match results in an impedance step-up from the 50-ohms input/output. As a result the voltage in the centre section will be higher.'

I think you'll find the so239/pl259 combination as well as the bnc were first standardized by the military and then the commercial industry picked them up. Unless you can find a bus standard that has

gentlemen, the question is closed. I connected the cheapest computer speakers with a built-in amplifier and sent a signal to them bypassing the amplifier uBitx. I got a good audio. and "A re-setting

By posting to this group I can only assume that the original poster is more interested in a smear campaign than in finding resolution to his problem. As ham radio operators we are expected to be

I agree with Jerry. ?I have a v3 utbitx with a socketed TDA2822, it works great and I prefer it over the discrete amp used in version4. ?I built that same circuit in Pete Juliano’s 40 meter

Jerry: All thoughtful points, many of which I didn't even consider. I remember trouble shooting the S100 bus using "extender cards". It made it possible, but it wasn't ideal. Any "rank mount" has to

I have been a ham for over 40 years and in all that time there is not even a 'standard' for the microphone jack. Even if the plugs are the same type , the wiring is often different. Even the 12 V dc

Andy After listening to your video it seems obvious that you have the BFO frequency too far down the IF sideband. That high pitched noise is an indicator. Move the BFO frequency to about 6 db down the

The uBitx and Bitx40 are attractive for many different reasons.? Some want a simple ham rig, and have a bit more time than money. They'd rather spend a day putting it into an enclosure and than pay

Jack After attempting to discuss this with a local ham, it became obvious that the idea of a "Standard Ham Radio Bus" is many things to many people, and maybe not a manageable concept. It sort of fits

On computers, a standard bus makes sense, they are just shipping around data and don't care exactly how that happens so long as it is fast and error free.? And maybe some source of power.

Larry has the right idea with #2. also allows you to tune around the frequency and see where the "dip" is before you start adjusting the tuner/antenna. 73 Kees K5BCQ

Thank you Hans. Somehow I knew you were the man with the correct answer. Iz thanks for asking the question I myself had pondered. Now we both have our answer.

In all due respect, sir: If I were the subject of your ongoing tirade and one trick pony show I doubt that I would dignify your opinion with a reply. I believe blaming the maker of XYZ being accosted
