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

Arek has also uploaded a Video YOU TUBE for his Bitx

Keep watching have fun, we shall bring in more news about some new developments with our new
Bitx kits. 

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.

Bitx3C SBL-1 Exciter 

Very soon video of Bitx3C SBL-1 with DDS will be put up on this site and You Tube.

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.
