New Kit: JBOT HF Linear Amplifer
After a gap of long time I have been able to bring out a new kit, from our most popular author Ashar Farhan's collection. Yes its the JBOT kit.
The JBOT has been tested on our designed PCB and works extremely well.
We have used 2N2218, earlier we used 2N2219 which had an higher gain and was giving some problem, but we have found 2N2218 more suitable and also as suggested in JBOT article.
We got a pack of 500 transistors 2N22I8 and so we are glad that we can offer transistor that have been tested and do not oscillate.
We changed just 2 resistors value as per the need of the gain of the transistor, and the complete kit was build as per the article.
Kindly find pictures attached below:
This kit can be purchased from our ebay store.

New Pictures from OM Arek SO5HMI Bitx3C
The earlier pictures of Bitx3C sent by OM Arek from Poland were without the complete wiring etc, so I had requested Arek to send me some of his Bitx3C pictures with complete built up set.
So now we have received some nice complete built up pictures of Bitx3C ADE-1 from OM Arek SO5HMI .
Enjoy them. The construction is excellent so as the working set Arek.....Many Many DX with your Bitx3C ADE-1

Bitx3C From Poland
Recently there has been lot of Bitx building activity from Europe ,radio amateurs from Russia, Poland ,France And Germany are building the Bitx3B and Bitx3C.
We have received some nice build pictures of Bitx3C ADE-1 from OM Arek SO5HMI from
Poland. Congratulation to Arek for completing his Bitx3C and also helping his friends build the Bitx.
Here are some pics as below sent by Arek for Bitx3C ssb tcvr with ADE-1 mixers

Bitx Case In New Colour And Models
We are trying to bring some new colours and models for Bitx Case .
One of the new colour is Black And Silver , this is available in two models, the first one is
the Bitx case with additional provision of Menu switches. So now the FLL counter swithes can be mounted on the Front panel of case.
The second model has the facility of mounting DDS function switches on the Front panel. The Encoder is fitting on the Tune control.
We shall be also offering a DDS very soon, that will fit on this Bitx DDS Case.

Bitx Version 3C SBL-1 With DDS
As promised earlier I am publishing some pictures of the Bitx3C SBL-1 with a DDS for 20mt band.
The set is working absolutely fine with good receive and transmit of 7 watts.
This present set is mono band, but the idea was to use a DDS and also provide DDS with the Bitx 3 kits.

AGC Bitx
In our earlier pictures for the AGC module, there was a connector placed in a wrong direction and also the trimmers were placed in the opposite direction.
We are publishing the correct placement again for the mentioned items.
Some care is to be taken in handing the VU meter as it is quite fragile. Instead of soldering the pins of VU Meter to the AGC pcb it would be better to solder short piece of wire pair and connect to the AGC pcb.
The audio mute pcb is overlapping the PA pcb this happened as the PA pcb was modified for the diode RXcut off switch, suitable spacers can be provided to raise the hight of the audio mute pcb while fixing on the case.

DDS FOR BITX VER 3 SERIES TCVR'S
Test have been done with our DDS to be used with all our Bitx ssb tcvr's .
A 20mt Bitx3C- with SBL-1 mixer using DDS is complete and in the next week we shall pubish some
pictures of the completed set.
Pictures of the DDS we will be using in our kits. The mono band tcvr can use either FLL freq counter
or the DDS.

Bitx3C with DDS And 40mt Bitx3C.SBL-1
Its been quite some time since i posted any info regarding any new development for our Bitx 3 series
transceivers.
The latest info that i wish to share is that a DDS is ready that can be used with all our Bitx versions, presently for mono band use and very soon for multi band use too.
I have been testing the DDS with Bitx3c SBL for 20mt band , and very soon it shall be boxed up. The DDS kit we have connects directly to PIN 8 of SBL Mixer while PIN 7 is grounded, no mod is required at all. The FLL can be replaced with the DDS if one wishes so.
Bitx 40 mt series with all versions B And C will be offered as kits very soon.
The 40 mt Bitx 3C SBL-1 has been tested and it gives an output of 7 watts with 24 Volts power supply.
Some minor work remains of connecting the AGC module and Audio Mute module and Boxing it up.
Very soon I shall upload some pictures and video of Bitx 3C SBL 40mt band and also the Bitx3C SBL-1 with DDS for 20mt band.
Catch up with you guys soon.
