New Frequency Counter dl4yhf PCB [Emitter Not Grounded]

The New Frequency Counter PCB is ready and has been shipped to a few Hams.
While making a new frequency counter with the new PCB I found the counter was not
reading the frequency from my Bitx VFO,but after inspecting the counter I came across
a missing ground for BC547. The pad of BC 547 Emitter was not connecting to ground,
after suitably grounding the Emitter of BC547 the frequency counter starting working to
satisfaction.
Such errors do come by and we regret them.

Home-brew bitx 20 version 3 of Anthonio Pagano I8PGO

Some exciting pictures of Bitx Version 3 have been sent by our friend Vittorio from Italy.
These pictures are of the home-brew bitx 20 version 3 of Anthonio Pagano I8PGO


Anthony has effected some changes, replacing the driver 2N2219 with 2N3866 and also changing the final IRF510 with the most strong IRF624. Besides has incorporated the indicator of frequency with display.



The Bitx 20 of our friend Anthonio has a very good look and constructed in a very planned way.


We wish you all the best with your Bitx and wish you have plenty of qso's with your rig.

Frequency Counter PCB] [error corrected]

Our friend Jean Scott F1BGY has sent in some more pictures of the correction done on the
frequency counter,so if you have purchased the Freq counter PCB recently,then Kindly do the
small correction.
The new PCB for counter are ready and further orders for counters will be done with the delivery
of new PCB of frequency counter.

Frequency Counter [Error in PCB]

An Error has been found in the frequency counter pcb design by VU3WJM . The errror has been found in the five digit mode LSD and MSD,which have been swaped,that is the display on the left the one driven by NPN transistor should have been the LSD.

New PCB for counter will be available soon with the rectification of error. Meanwhile friends who
have already got the freq counter PCB could correct the error by swapping the FND connections going to the cathode of the 5 FND.

Our friend Jean Scott F1BGY has sent pictures of his frequency counter with the jumpers
swapped in the correct position. "Thanks Jean for the beautiful pictures of your frequency
counter."

S-Meter For Ham Radio Tcvr

The Bitx design lacks an S-meter and adding one would be great in displaying a relative signal strength. Presented here is a one transistor ultra simple S-Meter designed by F6BQU Luc

Very Interesting our friend Vittorio Bruni IOVBR has added this small wonder S-Meter to his
Bitx Tcvr and sent us some more pictures of his Bitx with the S-Meter installed.
Well done Vittorio! The beauty of Bitx is that we can add on circuits and see the results and get the satisfaction from the outcome.

I would request all my friends who are making the Bitx to send me some pictures of their
Bitx,it does not matter if your Bitx is still under construction.The real charm is seeing so many Hams attempting to make the Bitx Tcvr globally.

Ham Radio Qrp Tcvr Bitx. Hombrewed By Om Vittorio Bruni IOVBR New Entry

Our Friend Vittorio has finished with home-brewing of his Bitx and has some excellent comments on the working of his Rx. I am posting some comments and pictures as mailed to me by Om Vittorio Bruni IOVBR

Dear Sunil, my BITX20 works very well ! Now it attends a new suit (cabinet) that I will prepare soon. Vy 73 de I0VBR, Vittorio - Terni - Italy

ALL THE VERY BEST VITTORIO. Congratulations for your Bitx

Vittorio has sent some new pictures with his ATU alongside his Bitx Qrp Tcvr. The ATU seems to be a very good piece of Ham Equipment!

Ham Radio Qrp Tcvr Bitx. Hombrewed By Om Vittorio Bruni IOVBR

Our very good friend Vittorio Bruni IOVBR has sent us a very good picture of his Bitx Version 3 Tcvr. The Bitx looks excellent with a very nice construction work done. Hope we can get some
more good pictures from our friends who have home-brewed their Bitx.

Thanks Om Vittorio,we appreciate your hard work. There are many hams friends of Om Vittorio who have started building their Bitx. We welcome any pictures sent by friends,so that they can be posted on Cqbitx,the home for Bitx Version 3.
