But Joel.. Can you still buy the v6 from HF Signals as
the website is so old? I'm loathe to part with money if I
can't verify if they still exist or the prices are

Re: ubitx audio amp problem discovered
Andy,
?
I do not have issues with toroid transformers.? You find the equivalent inductance on this page based on core material and turns:
?
You then set a link directive like:
K1 L1 L2 .98
which sets the linkage between L1 and L2 at 98%
?
Attached is a complex model with several transformers and toroids with multiple windings
?
There are good tutorials on the web here:

Re: sBitx V3, (PSK,RTTY,Olivia,MFSK) And More, Fldigi, Short How-To

We ars the same company that started with Bitx version 3 kits a decade back and still produce the Bitx kits as Easy Bitx Single band and dual band.?
This is just for?your reference to your inquiry.

Hi Dave,

Gerry is correct on the V6 still available and the current version.? The free software upgrade that improves the CW operation is available in the files section of this group:

The software was modified by VU3GAO and is available also in the files section.

I've just unearthed an unmade kit that I bought in 2018.
Is it worth continuing or has it improved beyond all recognition
in the past 6 years?
Are the assembly instructions still available?

Re: ubitx audio amp problem discovered
Thanks Evan - excellent point about following the signal to see what it has to 'squeeze' thru.? It would be useful to see what comes from the mic as well.
?
I've wanted to look at this since DHL delivered an early BITX40.? I'm excited to get this stage working better!
?
I was feeling pretty good about spice until I tried to look at an RF amp stage with toroid transformers. Yuk!?

If it helps, I've used the N7DDC ATUs in both my ubitxv6 and sbitx v3. I just but the kits with no enclosure to build internally - something like . Not recommending this specific vendor - there are loads of them on Ali and ebay.
