Greetings from Canada, from an eighty-year-old retired
electronics/electric professional engineer, hobbyist, and radio
Let me start by congratulating you, Ashhar, for your dedication
to and for the success of your work. It's great that you have made
it available to old and new generations of smart radio
enthusiasts. Great work. I mean it. Keep it up.
I was just disappointed by the lack of instructions/info with the
kit and its poor presentation - a list of parts on a clearly torn
half-sheet of paper, and an invoice; that was all I got. And,
pardon me to differ, also a bit disappointed by the quality of the
parts that came with the board. As an Arduino
hobbyist/project-builder, when I order stuff from China (through
ebay) I expect "minimal" quality but, I confess, I was expecting a
little better from HFSignals. I realize that some economic factors
are involved, on both sides, that have to be considered.
This is a great group. I have been following it for a while now.
I also admire that you often take part in the discussions. Gives
the rest of us the feeling that we are all in this together. Some
of the guys here are tops, and I will be coming back for help,
guidance, and learning. (Yes, old dogs can learn new tricks.)
I am not one to start or enjoy debates online. I did not want to
start one. If I had given careful thought to my post, I probably
wouldn't have done it. (BTW Ashhar you have some loyal and though
supporters here. Ouch!)
My apologies if I hurt some sensitivities. And my thanks to those
who understood my main idea and took the time to write.
This will be my last post on this subject. Cheers to all. You are
all doing great work!

You are refering to the BITX40 kit, rather than
the uBITX. I entirely accept that the presentation could be
better. I am working on updating the BITX40 documentation and
it should be through in a week.
However, on quality, I have to be a little
First, we use high grade components through out.
Our toroids are from micrometals our encoders are original
You mentioned the 'crappy' tiny ptt button and
mic. Considering that our goal was to ship an entire SSB
transceiver for well under the price of a standard radio mic,
instead of not shipping any mic at all, chose to ship a very
fine electret mic. It is a Panasonic that forms the main
element. It has had very good on-air reviews.
The small ptt microswitch is what many mics have
inside them. Just like there is no casing for the transceiver,
there is no casing for the mic either.
All inductors are measured before they get on
the PCB, crystals are matched. After assembly, each board is
tested and signed.
As for the firmware, it ships with the latest
version. If you would like more features, you can try this https://github.com/amunters/bitx40
it is a great piece of software engineering by a very talented
If there are any specific places you get stuck,
do ask on this group. We are an open community, open to self
PS the 0.1 uf is a spare to help you eliminate
RFI. Depending upon how you wire up the BITX 40 and into what
kind of enclosure, you may need to solder it across a control

that I may have miss-interpreted

posted some thoughts that
we have all had from time to time. I probably
over-reacted a bit.

I'm curious on out the research you
undertook before purchasing a Bitx40 that lead you
to expect anything other than what you got.
Everything not on the PCB is really included
for two reasons:
1) to enable someone without access to a
well-stocked 'junk box' to complete the radio, and
2) minimize postage
I'm not sure what I'd change at HFSignals,
except maybe include a somewhat more informative
'getting started' document, but it would have to
be multi-lingual, since the market is truly

I have been wishing to order a
Bitx40 for a while now. Meanwhile, I have been
reading the posters of this group from time to
time. I kept reading about the problems people
were having with the radios but, I think, I
had to experience it myself.
Maybe I am just a sucker for punishment. But I
did not expect the experience to be this bad.
The order was delivered on time. So far so
good. The packaging was well done and strong
as if it was expected to go through hell and
come out unscathed.
The surprises came after - The quality of the
components can't be any worse - very cheap and
poor quality pots, a tiny push button for PTT
(are you kidding me?), a lousy mic and a 0.1
uF capacitor that I still have no idea where
it will go.
There were no instructions of any sort. Not
even a link to a website where they could be
found. One half-page of an 8X11 sheet of paper
with a list of the contents (probably to save
on expenses), and an invoice, was all that
came with the parts. No even a mention on the
version of the board and/or software. What
version is it being sold now, anyway?
The whole thing is crappy. Is this the way
they do business in India or is it just a
company that doesn't know how to do it?
This post will probably have some replies
telling me that I should have known better.
Maybe. For hackers they say?
