Ebay Store Kits Out Of Stock?

Mark Baldridge
 

I was looking at finally ordering a kit, and now they all seem to have disappeared. Only the PCBs are left.

Do we know if/when they will be available again?

Thanks all!

Try ordering direct from India. It takes a few weeks, but that's how I got mine.

Thanks Mike!

I have a few questions:

1. What is story behind the two different sellers?
There's hfsigs.com like you mentioned, and then what I was referring to:
Sunil Lakhani VU3SUA at https://cqbitx.blogspot.com/
and he's selling his kits on eBay as sunillakhani

The kit I was thinking I wanted to buy was:


2. Would I want the through-hole version referenced or the SMD version you linked to?
Which would be better for experimenting or modifying for other bands?
I also see that the SMD version is already assembled, and cheaper! $45?

I appreciate the input.

Thanks!

Mark, Sunil Lakhani and Asher Farhan are in completely different companies.

Sunil brought out the BITX20 v.3 some years ago (with Farhan's blessing). He has since expanded the line considerably; parts are available from only circuit boards to complete rigs as kits. Sunil has a long and respected tradition in the BITX arena, but he has no smd kits as far as I know. I have bought several kits from him over the years and have always been treated well. They have become more expensive over time.

Farhan invented the BITX and has been involved with the various permutations over the years from start-up.
He has decided to market the smd BITX40 partly (or mainly) as an aid to a womens' group in India. At first, the kit was available only in India, but has recently become available internationally. It is only the second smd version that I know of; the first was by eliamady back in 2009. I have the BITX40 and also the eliamady smd version of the rig. (I will probably post pictures of both for comparison to the group shortly).

As to which one to use...that is kind of a personal question -- it depends...

Sunil's rigs are through-the-hole construction and are designed more or less for complete assemblage by the user, except for making the pcb. Their principal advantage is that missing or different parts are commonly available most everywhere -- including where you live. Asher's rig is pre-assembled and smd, but one has to figure out how to put it in a box and make it work without assembling the main board (or boards). Both are essentially the same design.The one radically different BITX was probably the BITX20A with its push-pull dual output PA. That also is still available.

Every single BITX has been tweaked and modified over the years for one purpose or another. Both Sunil and Asher (as well as everybody else) encourage innovation to make things more to the user's liking. The best general summary I know of for the circuit is that of F8VOA, which has all the good mods in it. It is an excellent reference. The next best reference is this list. Search for any topic and you will probably find it discussed somewhere on this list.

Hope this helps.

Thanks for answering John. I didn't know as much about the history. 
I have Ashar's SMD version, and it works great, but I wouldn't mind a through-hole version in case I needed or wanted to replace a component. Replacing those teeny tiny SMD parts can be quite a challenge. :-)

Are the surface mount parts mounted by the woman's group?

Ha ha! By machineries, as to decrease labor cost & time, otherwise it cannot be so cheap...
BTW, torroids finds way frm pretty soft hands...
Personally inspected & serial by Farhan (Y)
( not hands but BITX, joks apart ;)

Above all previously mentioned already by 'F'
Hats off, a new trend..

Again machineries cannot do everything, soft hands is for sure...

Our new batch of Bitx version 3B 3C kits,shall be available by the end of this week on our Ebay Store. We start with 20mt kits followed by the Bitx Version 3B 3C 40mt kits too. 

Thanks for your patience and great support.

I have a BITX 20m v.3 PA PCB from the ebay shop of Sunil VU3SUA. It has two amplifier stages and two transformers. The description says it can be modified for 40m. But it does not say how.

How many bifilar turns on FT37-43 should I use for the driver and final transformers when I build for 40 meter / 7mHz?

Thank you.
Roy

I just want to say thanks guys for the clarifications. I think for the fun of it I'll be building mine with a through-hole kit. I just feel like I'll have more fun modding it, and it'll look older and cooler. :)

Also planning to add a CW tone generator to it.

THX, KC9DZT Mark
