Bitx20 and other Qrp projects

Cqbitx was started in 31st July 2000.   That is 10 years now.  We have contributed to the cause of Bitx and have never mentioned that Bitx has to do anything with our contribution towards the design.

We have helped more then 300 members with Bitx 3 Kit as by Ashhar Farhan and Mods by VU3WJM.

Infact from day one we have placed links and given correct info about the authors. Many Bitx version are in the making, we had started this blog to help Radio Amateurs to get kits for Bitx Version 3 as modified by VU3WJM.

In a hurry to publish our new website , we had un- intentionally  not mentioned the author, but had placed links to Bitx Forums and Sites. But we have corrected all the content as regards  to giving due credits to the Author and Contributors.

Bitx 20 name is very appealing as you can understand my sentiments, that I have worked day and night for 10 years promoting Bitx Kit and info world wide with many other kits too.
So by launching a website with Bitx20 domain does not mean that I am misleading or taking credits.

This is a free world and anyone can book a domain name if it is available, and since I am already working for Bitx, so its very easy to under stand why I like and booked Bitx20.com

I have an interest to promote many Kits and offer Hams world wide with Kits. I will also be booking new domains like for Bingo. Avala,etc etc. so does that mean I can not book these names as they are work done by others?
Infact I am making the projects more popular by dedicating my time,my money and efforts, those claiming that I did wrong in naming Btx20 should study all hard work for so many years by working days and nights to just help Ham community. If I spent this much of time on a lucrative business then I could have made many money spinning websites. But since I am a true Radio Amateur , helping hams appealed to  me as a good activity.

I am sorry for any inconvenience caused to parties that may be hurt, but is was a must to make my-self clear .

Building Bitx 3 , by the BiTX20 building group at 147.120 Tech Net

If you  want to keep a track of building Bitx Version 3 with the way friends at the 147.120 Tech Net are doing. Then please do visit their blog and see how a group project is being build with club members with test equipments.
They have build the FLL Kit which was start of their project.  Here is the link
http://technet.147120.com/technet/?p=401

The second meeting was to take up Bitx Bandpass Filter. Here is the link to the building and measurement with test instruments.  http://technet.147120.com/technet/

I think the test equipments have not helped them decide the correct capacitor.  We have made many Bitx and found 39 Pf the best value. That has been tested  in practical receiving and transmitting.   Lets see what is the outcome for club in the next meet.

The error in print is regretted . The PCB shows 68Pf but we have advised for 39PF.

All the best friends

 The Bitx20 website has been launched after remaining unfinished for a long time. The website will give in more details and comprehensive info regarding Bitx version 3.

Rahul  VU3WJM is working on some mods which should make the Bitx version 3 much more better and the errors presently in documents or schematics should be done away it. We would add some extra features , which we will mention when we have incorporated them in the new pcb's.

Also soon we will put on sale  PCB for LSB/USB change,  Crystal Filter For SSB/CW,Band Pass and Low Pass Filter PCB.   We are waiting for TOKO coils so that we can give complete kits for Bandpass and Lowpass Filters.


New items will be placed on Bitx20 site  soon, so keep a watch on the site http://www.bitx20.com.
If you have any suggestions for the website then kindly do email your suggestions.
