Low RF Gain In Bitx 3
If you experience low gain in RF amplifier of Bitx 3 Or Bitx Multiband then please check out the
2SC2570. We request you to kindly change the 2SC2570 .
I have had problem sourcing good quality 2SC2570 and some of you may have had the
one with low gain, supplied in the KIT
If your 2SC2570 is not as per the picture below then kindly change it with 2N3904. You would need to change the PIN connections for 2N3904 .
The picture below is of a good quality 2SC2570 if you are having this type it is ok. The lot number is also given on the transistor.
I could not get a good picture of the one with low gain, as the marking is not good on it, i will post a picture of it soon.

New Version Of Bitx Version 3 Demo
The Bitx Version 3 New Version PCB is to be launched soon.
The following changes have been made:
1. Varactor tuned VFO with connection of FLL freq counter. We have a video below showing
a demo with the new Bitx 3 version connected with the IK3 OIL FLL Counter but the VFO is of
bitx with some changes. The first transistor is BF245 with varactor diode tune,covering complete
band.
2. Mic Pre amp stage has been added to now its quite sensitive .
3. Increased Audio output.
4. Audio Amp mute as the PTT is pressed , this was required for keeping the relay from making a noise
on pressing PTT.
4. Point for connecting optional AGC and CW.
More news soon.
Enjoy the video posted below in New Bitx Version 3 coming soon.
