Bitx-3 By Marcel Jacobs- Netherlands PE1LNX

Good News coming in From Netherlands our good friend Marcel Jacobs   PE1LNX , has completed his Bix Version 3 and sent us some beautiful pictures of his astonishing Bitx-3.

Marcel has constructed the Bitx in a very  attractive case , which happens to be an old transmitter.
The handle and Meter are giving it a professional look. Congratulations Marcel .

Here are some words straight from  Jacob  Marcel on his Bitx..

"As promised, I sent you some pictures of my final version of the BITX20 with the FLL VFO. The housing is an old air navigation beacon transmitter. 

As you can see, I didn’t assemble the PA completely, because I am still busy, building the 4 meter version.

Because of my vacation, and very good weather, is goes on a little bit slowly. But I will keep on going."

Thanks again Jacob, keep the good work going....

As I have a policy of giving exposure to every one who makes the Bitx-3. This time the honor goes to Jacob Marcel for his Bitx.

I greatly appreciate all my friends who have contributed their pictures and videos of Bitx, And hope to keep this system working ......

Best of 73s and Good Luck

DL4YHF Frequency Counter kit

Ramsey HR40C 40 Meter QRP Amateur Radio Receiver Kit

Many of my friends have built the DL4YHF Frequency Counter kit that we sell and many more are in the process of building it.

Before you build the kit, you are faced with a decision as to how to build the kit, you may wish to build as all components mounted on front side of pcb, that as absolutely fine but if you would like to mount it on a panel they parts may obstruct the mounting so you are likely to mount the components on the reverse side of the pcb. Now comes the tricky part.

I would recommend the method of mounting the components at the reverse side of the pcb only when you are good at soldering parts, the tracks of the pcb are quite narrow and fragile, so outmost care has to be taken in doing so. The soldering Iron required is to be of low wattage as not to damage the tracks.
Finally you should be ready to face some risk of repairing tracks and pads if broken while attempting the build of frequency counter.

I have made one of the Frequency Counter on the reverse side and I also had a minor brake of pad while mounting the power pins, which I joined with a small piece of wire.

I have published some pictures of the Frequency Counter and the various functions that can be viewed by pressing the function switch to set your frequency reading options.

We hope that the pictures published have given a view of the different options available with setting of the

frequency counter and what way would suit you best to build it.

                                    

DL4YHF Frequency Counter kit.

The month of June could not allow me to post any new news on Bitx as I was busy with setting up a new office with more space for getting the kits made,packed and shipped.

Recently I came across an error in packing of  one resistance  in the DL4YHF Frequency Counter kit.
There is a 470 ohms resistance which was mistakenly packed with a 4K7 resistance.
Kindly correct the value to 470 ohms or the freq counter would not read any freq from any external source.


The frequency counter picture is being published here to show the location of the resistance 470 ohms.

One kind suggestion is to use a low wattage soldering iron for soldering the frequency counter components,or you may brake some tracks with a high wattage soldering iron.


Thanks and we are extremely sorry for any cause of the time you may have spent in locating the problem to get the frequency counter working.

The pictures are being published of the following :

•  FLL counter with Hartley VCO

•  Experimental LPF for VCO, based on SVCFilter calculation

•  The SVCFilter(freeware) calculation

•  BITX20 version3

•  Front Panel Bitx  first setup design made  by Jacob

Congrats Marcel hope to hear your Bitx qrv on air waves someday.
Keep it up and all the best
