Hi! Few friends have shown interest in making a double sided board for BITX with top layer unetched and acting earth plane. I have uploaded the artwork files to make it easy for them. Missing hole

Hi! It would be a simple matter to upload the interconnection traces only less the earth plane. I will simply reamove the earth plane from V3 layout. Friends wishing to use a double sided board

All, I'm starting to need reading spectacles, so I took the liberty of redrafting the schematic submitted by Mr. Farhan into a series of modular documents that should take somewhat less effort to

--- Hi Allison, I'd never thought of WWV being a problem in this respect in North America. You are right.It would be annoying to hear that Tick -tick all the time. I will have to consider some

Hello, Comments are inserted inline. I prefer a two sided board where the component side has no traces only clearance holes for non grounded components and holes that are not clearanced so

Most of this V3 board is IF and BFO and as such is well shielded by the prolific ground plane on it's single side.I like this type of layout as it avoids a lot of ground loop problems. To get up to

Hi, It's size and the lack of two sides (top ground plane) make it less than useful for my 6m project. I'm saving it for something else. I mentioned it so others may know that FAR has it. Myself

Hi The last time this item surfaced, I was selling it for a dollar a foot. I think I can do that again. It's a reel of 20 pF NP0 disc capacitors on paper tape, with 1 inch leads, 24 per foot.

Thanks Rahul Jim VE3DDY higher gain and lower NF. So the pin out is B-E-C which is different from other transistors. C-B-E L-R for other devices. For 2SC2570 you cab also substitute BFR90.91,96 or

Hi! For those going in for ver3 board , I once again repeat the mods. 1) Q1 I have used 2SC2570A a high ft cable TV transistor for higher gain and lower NF. So the pin out is B-E-C which is

The Far circuits boards are away too big for my application so I'm strongly considering a run of the CCA design by VU3WJM (Rahul). This board design is 6.5 X 4.25 inches and will fit nicely inside

Hello, This may not be of help to everyone but for North Americans it would be handy to know. FAR circuits www.farcircuits.net They have the the BIT-X board as drawn by the creator. The one I

Hi! Friends Unfortunately we have still not managed to get the BITX PCB commercialy manufactured even though it is quite cheap getting it done here. Secondly postage from India is also rather

Hi Arv, and Group, I've been looking at the CCA Version 3 by VU3WJM as it fits the 884 packset like a glove. I have to find someone who has that board available or else gear up to make my own. I've

Jim VE3DDY One of my BITX units is built on a 7 inch by 4 inch PCB, including the PTO/VFO, a Huff & Puff stabilizer, and three additional transistors for T/R power switching. It is a bit tight, but

Hi BIT-X'ers, My name is Jim and I'm new to the group. I'm a Canadian Radio Amateur and an avid experimenter. I have an old Chinese type 884 VHF radio packset into which I'd like to install a Bit-X

Hello, I have also done transverter for 2M in the past as well as 2m RX designs. A good filter for 2m can be done with 3 coils of helix design using aperture (window) coupling. Constuction is a 3
