Gilles, Jack has announced the JackAl board will be distributed by *QRP Guys.* It will be added to their website when he has stock of the kit, currently expected end of November.* *

The information I read says it is aligned at the factory and other information from HS Signals says that 'alignment' and 'calibration' are the same things. The expectation is that it works right out

I ran across this in a FB post.? Thought I would share.?? It would work with any of your projects that you need reverse polarity protection.? I've been saving articles, but this looked like a

Hi Kack & Al I have two questions : 1 - Can we buy only the kit of the card? (I already have a TFT 5 "and a Teensy 3.6). 2 - Do you know a book about Teensy to learn how to use it or have written one?

I mainly use 20 and 40. I always go to 20, and then 40 if there is no activity. 80 has lots of activity at night, but I hardly ever hear anything other than rag chews and nets down there.

I have been following this thread on Bitx40 vs. ubitx.? I understood the question to be a comparison between the Bitx40 and the ubitx 40m.? Anyway that would be my question....so are there any

Thanks for the suggestions Iz, Ill be checking out the RTTY contest for sure and I do have a need for some 1:1 transformers, Ill order some and give it a go. One thing I did last night seems to make

Several have asked the question if a Teensy 3.5 will work with our BITeensio board for this application.? The answer is NO because, as far as we have been able to determine, USB "Host" mode only

Indeed Russ, it may have been just by fluke but mine arrived perfectly aligned (actually almost perfectly, 100-150hz off the actual frequency) so I assumed that in most cases it was delivered

And right off the bat... I wonder why this is mentioned on the HF Signals website? "The ?BITX comes pre-aligned. You should do this only if you really think it is out of alignment."

Hi, can someone tell me a simple way to add a ptt switching circuit for my amp please? Can I just use pins from the transmit relay?? Thanks.

Doing a smoke test does not include setting the BFO! No where on the site does it mention that the kit comes pre-calibrated. The software is written to get the frequency close to being aligned. Due to

iz. don't confuse the poor bugg_r There is a procedure for set up .? he needs to follow the procedure to get optimum output in SSB.? Now you bring up a red herring.? What I would find annoying is

Why don't you measure the power and current draw in CW key down?

Thanks guys, I had sort of considered that the Bird 43 was probably not showing peak power being that it’s not capable of without the add on kit being done to the meter so that confirms my thoughts.

Good news. Would be nice Farhan could make a stand alone VHF UHF SSB/CW qrp rig to be used for sats, sota and contests in general. Il 26/set/2018 00:55, "Bill Meara via Groups.Io"

I would like to point out two tricks to reduce noise that worked for me using cheap sdr IF converters. First if you use a laptop, either use the battery (which will be eaten fast) or a power supply

Ok, interesting that a resistor may suffice. If you hear overload in the uBitx then you need the BCI filter or adding some preselection. If you see the overload in the RTL and you hear a clean signal

Russ et AL , these are the Bias instructions? straight from the? ubitx website. It would seem to me that the unit went in the box without bias being done.? ?Rebias (not sure about the Re.. it may
