Farhan,
My vote is for a separate HF1 group. It would greatly simplify things.
Simple is better.

arv,
i am keeping those options open for the Si5351 advocates. one could even use the third output for the bfo. for me, i will stick to the Si570. not only can i solder Si570 easily, i am also so used to the low phase noise of Si570 now, that i can't possibly go back to anything noiser.
i am not sure if we can manage another group. but if the HF1 is close to the bitx design, can we look at discussing this the bitx group itself? what's are your thoughts?

From a first glance at the schematic it seems that you have addressed
spurious emission problems that plagued the Minima layout. The new
mixers are quite interesting as well.
Are there any plans to replace the Si370 and 3X-18MHz oscillator with
a single Si5351A synthesizer? It might even be possible to use
the 3rd
output from an Si5351a for sidetone and tune-up signal generation?

Will you be starting a new discussion group specifically for the HF-1?
I will be watching for the project documentation on your web site.
Thanks,

ok, here is what you all can do.
go ahead and make whatever you can out of the body of work of
minima with the following caveat:
1. to keep minima distinct, i wouldn't like these boards or
version to be callled the Minima or Minima version x, y z.
Choose a different name.
2. if you design is substantially derived from Minima, then it
should be available without any restrictive copyright.
3. the software is under GPL, thus any derived version must be
available under the GPL too.
on the other hand, i have completed a much easier to build
(though slightly more part count than the BITX) all band
transceiver called the HF1. It uses diode mixers and the same
audio back-end as the Minima. The HF1 is a double conversion
transceiver with the first IF of 45 MHz and the second IF of
10 MHz. The first oscillator is the Si570 and the second
oscillator is 18.432 MHz crystal in third overtone. I have
been operating it extensively for the last few months. It is a
fantastic performer which is very easy to setup and build. I
am enclosing a circuit of it here for you guys to go through.
I will complete the write-up and post it soon on my website.
this grew out of my frustration with the Minima's KISS mixer's
oscillator leakage.

I am in U.S. now.
If someone can send me the GERBER I can do manufacture in

Please feel free to contact me anytime.

How much would it cost to ship to Italy?
On which version of the minima is based the PCB?
