One of my earliest memories at about 3 years of age, maybe less, is being fascinated by the console tube radio we had in the living room. Peering around in back, face pressed against the wall, trying to see what was inside and figure out how it worked.? My elders teasing me, telling me about all the little people tucked inside.? Younger hams in the states will only think of Ham Radio Outlet, our local retail chain. Here's the real HRO:?? And a choice quote:
The original published story for the origin of? the HRO designation related that all of National's inter-departmental paperwork for the receiver project was stamped "H.R.O." which stood for "Hellva Rush Order" since the time table for the receiver development was a "rush order" type of project. For many years this was the story related in National advertising and it sounded believable. However, after James Millen left National in 1939, he corrected the story as follows:
The original development paperwork was usually marked "H.O.R." - for "Hell Of a Rush" but during the finalization phase, someone at National decided they didn't want their new receivers to be referred to as "HORs" so the letters were rearranged and became HRO - then the "Hellva Rush Order" story created to explain the HRO designation.
Well,...that's Millen's story anyway.? ?

There have been numerous articles in QST over the years on
rebuilding these old rigs.? I found an article which I saved
somewhere on building transistor substitutes for the tubes.? you
could build them on small perf boards and set up a set of wires
that corresponded to the pin out on the tubes.? At one time,
someone was making modules to replace all the low power and
receiving tubes on the Collins S line.? That was at least 40 years
ago.? I don't do well on a lot of these tiny connections anymore
due to age and aging eyes, but my history skills are still largely
intact.

When I was young (at leas 50 years ago), solid state technologies were either in their infancy or still a dream.? Our rigs were two pieces of equipment, a receiver and a transmitter with a variety of accessories.
Most of our receivers for those of us who were not well heeld in the financial area were of the single conversion genre with an if frequency of 455 kHz.? With little preselection capability, this relegated the ham bands 20 mtrs and above useless with hetrodyne images from frequencies 910 kHz either above or below the desired reception point. There, in that day, were three remedies to fix this. The first two were:
??? 1.)? add a really selective high gain preselector to tune the offending images out
??? 2.)? raise the if to something on the order of 1600 kHz which left bandpass selectivity at a substantial disadvantage.
The third option, and the most expensive in its day was double (or, even triple) conversion.? If? you were able to pay the 1958 price of over $300, you were in and there were few difficulties thereafter until the receiver aged and developed some bad shield grounds or worse.? The second or third conversion local oscillator would provide a cornu copia of birdies of one type or another. These included signals that were always there, I know the newer designs with balanced mixers and the like have few of these problems, but, it is worth considering.

Re: RD16HHF1 in the uBITX
#ubitx
Curious.
Farhan recommends 100ma of bias through each uBitx FET, same as the Bitx40:
? ?
WA2EBY recommends 10ma in part2 of his writeup.
It does make sense on the Bitx40 to have a heavy quiescent current, since it is not push-pull.
You definitely want to zero the bias pots (RV2 and RV3 both clockwise on the uBitx)
before powering it up with new FET's, and then carefully adjust for the desired quiescent drain current.
Even if the new FET's are from the same lot as what was replaced, as the Vgs threshold?
can vary significantly from part to part.
Jerry, KE7ER
HFSingnals? bias current through each FET of 100ma can remain as it was on the uBitx.

Excellent, thats what I am hoping to get to.
So the bias will need re-adjusting... Easy....?
What about the input and output transformers? I assume this will need modification due to the differnet impedances of the IRF and RD...
Thanks everyone for your input so far.

Subject: Re: [BITX20] Case
I always enjoy seeing how others have built their BitX's and thought I'd point out some ideas I used with mine that others might find useful. For example:
1. Almost everyone places their tuning control to the right, but if you place the Raduino to the right you can easily update and play with the software by just plugging in to the USB port.
2. It is hard to beat the value of the Banggood instrument case. If you turn it upside down and eliminate attaching the hard plastic feet you have a smoother mounting surface for circuit boards and can use the vent holes for a speaker grille. I added some stick-on
soft plastic feet on the "new" bottom.
3. While I still want to find a nice way to attach labels to the panel, using the second line of the BitX display is a convenient place to label switches and controls.
