Gerry,
Yes, it's a great chip. I have one tuned to my 700Hz sidetone (lights an LED), so I know when I'm right on frequency with another station.

Re: Best wishes to our friends in India
I think it's less the Thalidomide situation than politics.? $200 is a lot cheaper than any other price I've heard/seen - a LOT cheaper. Enough so that when I heard about the paperwork... I was immediately suspicious.? It most definitely won't be the first time!
Lots of innocent lives lost in the last year (SIGH!).? I just hope we can save more lives today.

Hello Bob,
Your order is ready for shipping and will be done so in the next couple of days. We will inform you via a private mail the dispatch details. It usually takes between 5 to 10 days once dispatched with many even having received it? on the 3rd day.
Thanks and Regards,

Re: Homemade Circuit Boards
It took a LOT of fiddling and diddling to get it to work. I too, have a laminator. Actually two of them. It was VERY fussy re: board cleanliness.
The ultimate solution was a paper especially made for toner transfer.
This
stuff is magic. It floats right off in the water. It wasn't cheap.
I see Mouser has it. $13.71 for ten sheets. If you cut them in half, that's
enough for 20 good sized boards. Just google "toner transfer paper pcb". The
same maker has a foil that you iron over the transferred toner to protect it from etchant - because toner is porous, and you get ugly little holes in your traces. I haven't tried that.

Re: Best wishes to our friends in India
For those who don't know, Farhan and Gordon Gibby did Herculean work to develop a working ventilator that could be produced for about $200. Then, the FDA stepped in with massive amounts of paper work and pretty much buried things under that paper mountain. Like Friedman once said, the FDA likely has killed more people than it saved because of its knee-jerk reaction to the Thalidomide drug in the 50's and the delays that resulted from it.

The situation has been very depressing. It could have been
handled much much better. The second wave has hit some of the
cities very badly. They are out of beds, oxygen, drugs and
vaccines.
We lost many hams as well. Bhogi, who was probably a quiet
member of this forum, died last week as did slokapriya, who
also ran radiojitter.com <>.
People seem to have given up on distancing and keeping
indoors. It is a bizzare situation.
HF signals is working skeletally. I am fully locked up along
with my family at home. We are a large house with 9 people. We
play board games, carroms, bridge, read to each other and i am
working on the SDR.
My partner and the man dude of HF Signals, Ehsan, is just
recovering from a mild bout of Covid. Others are doing good.
Thanks for your concerns and we hope to see you all in the
other side of this nightmare soon.
Keep the solder burning, stay safe. Use science to fight this.

Re: Talk: Does price buy Performance or Satisfaction in an HF Transceiver? by Frank Howell K4FMH
I'll leave it to the experts to discuss performance. But, as far as satisfaction goes...
There's nothing like he thrill of making a QSO on a rig that you built yourself and being able to proudly proclaim "The rig here is homebrew.". I can tell you from experience that on SSB at least the other side rarely believes it?

ordered a uBIX v6 from Ashhar (HF Signals) on 22 Feb 2021,
received notice of shipping via DHL on 23 Feb 2021 and had it
in hand on 25 Feb 2021.? Way faster than I was expecting.?
Just my experience.

They use excellent shipping resources. Its a long way from
there to your qth. Also the pandemic is hitting them much much
harder than many of us. I suggest trusting it will arrive,
this ain't like in shipment within US or EU. If they have a
tracking number it would pretty much say it was shipped, and
next thing we see is delivery. Oh to ND, wow probably a few
days faster than getting to me in Central MD (-:

Okay, Frank and Curt.
That gives me some idea.? Your response is greatly?appreciated.

You might want to look at the data sheet for? the Texas Instrument LM567 IC.? This is actually primarily designed as a DTMF tone decoder, but seems to have a lot of other uses.? The web address is:
This will save the trouble of searching for it.? It's a .PDF file, and the IC is available in a standard DIP package.

Hi, All,
Just wondering...From the time you ordered the uBITX, how much time elapsed until you received the package?? Were you sent tracking information?
I didn't find a place on the website to add the funding for faster shipping, so I figured I could wait.? I certainly and not lacking things to do!? Hi.
If anyone could enlighten me, I would appreciate it.

Talk: Does price buy Performance or Satisfaction in an HF Transceiver? by Frank Howell K4FMH
Talk: Does price buy Performance or Satisfaction in an HF Transceiver?
Frank Howell K4FMH presents a fascinating insight into our modern HF rigs looking at their price, their performance as measured by Rob Sherwood and reviews on eham.net.
Do you get what you pay for??Are expensive transceivers really worth it?
Join us on this presentation to find out.

Only drawback we will see the support on 2.54mm, but it is the best
