Increasing Gain of LM 386

The Bitx may be giving a low audio output for some. To increase the output I searched for some articles on Sprat and came across an interesting article.With just a few mods in the existing board the audio Gain of LM386 could be increased by 2 to 3 times.

It would be interesting to try this out. I will be trying it out myself and will put up the results. would request my friends to try it out and email me the results.

New PCB and Kits

Some buy links for a few new Kits have been placed.
The following are the new PCB and kits

1. A two PCB set for DDS VFO, all info can be found n Ham Radio India. Org.
We plan to make this into a Kit, but presently only the PCB are offered.

2. A Linear Amp 50 Watts PCB. An article has been published in QST for this linear.
We presently offer this as a semi kit, which includes a PCB and 2 Final Transistors
IRF 510

3. A Dummy Load Cum Power Meter. This is a complete Kit. All info can be found on
Ham Radio India. Org

4.S.Meter with 4 Led. This is a complete Kit.

The case for Bitx is ready as informed earlier. I still have to make a small write up for it,and arrange suitable packing for it. But if any one is interested then kindly do email me for the case.
The front Panel is available in three types
1. All controls in one line with VU meter and LCD
2. The other design which is not in a straight line is available in VU meter LCD
and the second one with a Bar Graph S.meter and LCD.

Shorty I will put up pictures and details for a set of PCB that can be used for 2 bands, and a pcb for switching between LSB and USB and and as well as a PCB for switching the Filter for SSB and CW.

Bitx Version 3 By Inge LA1ONA

OM Inge Hagen LA1ONA from Norway has build the Bitx Version 3 and has made many
contacts with his Bitx.

He has sent us some beautiful pictures and a video.
Some pictures of Inge's Bitx are being published for our members.

Models of different panels

I would like to thank my friends in taking part in polls and expressing their opinion on the necessary controls on the Front Panel.
It seems from the poll that the best option would be to cut the VU Meter and LCD display box so that the rest of controls can be set as per requirements.

I am publishing some more pictures of the present front panel and a new front panel
with all the controls in a single line and no markings on any control, so that could be
done as per choice.

To provide variety is a fair challenge, so that is why companies that offer a case
provide it as a blank front panel.

I could also provide complete blank panel for some interested persons.
