Hendricks Kits

These days, with dirt cheap kits from China often with free airmail, it is sometimes a wonder that any USA or UK kit companies exit at all. One of these I have mentioned before is Hendrick Kits, which always has a good selection on their website. These are best value if you live in the USA. Several kits are shown as "retired" which I guess means they did not sell well or they had problems with reproducibility. One favourite is the derivative of the BitX SSB design from Ashlan Farhan in India. This uses easily obtainable parts and has been a well proven design. Hendricks sell versions for 20m or 17m.

It looks like they have just moved so there might we a little delay until early May.

The power out, around 10W, should ensure plenty of contacts. These 2 bands are usually good even when the sun is quiet, so make a good choice. You have to choose either 20m or 17m SSB. I am sure Western kit companies would really value our business. "Use it or lose it", is a phrase often used about bands. In this case it apples to amateur radio kit suppliers. If we don't buy from them they will close their doors and cease trading. I am as guilty as anyone having recently bought a 40m Pixie kit from China.

From the Hendricks Kit website:

"The BitX20A and BitX17A are complete SSB kits with board, all parts, digital display and custom powder coated and punched case that is based on the BitX20 that was designed by Ashlan Farhan. The original version was built ugly construction, and you had to source all the parts. I discovered the BitX20 site on Yahoo in 2007, and decided that the BitX20 would be a neat kit for Hendricks QRP Kits. The problem was that it did not have a pcb. A team of Dan Tayloe, Jim Kortge and Arv Evans have worked countless hours making sure that the pcb version was stable and would meet United States F.C.C. Specs. We had to go through several revisions to get it right, and we are happy with the result, even though it took a long time. Some things just take time. The kit includes a commercial quality plated through, silkscreened, solder masked board, and all board mounted parts, plus the polyvaricon tuning capacitor, digital dial, custom powder coated and punched case, knobs and controls. Everything you need to build the kit is provided.
I encourage you to check out the BitX20 users group on Yahoo. They have agreed to provide support for the kits. There are hundreds of messages on there about the history and development of this kit. Our kit puts out about 10 watts, features dual IRF510's as finals in a push-pull arrangement. The schematic is available at the Bitx20 site on Yahoo. Cost of the kit is $180.00 plus shipping and handling."

The BitX looks a nice, useful radio. For a beginner it is just about all you need to get started.

If I was looking for a simple, reliable QRP SSB rig for HF use in the coming years then the Hendricks QRP Kits version of Ashlan Farhan's BitX transceiver for 20m would be in the frame. They also do a version for 17m, but there is more chance of QSOs on 20m.  The rig has a useful 5W pep output and looks straightforward to build for most people. The Ashlan Farhan design is well proven. Going from 100W down to 5W is only just over a couple of S-points. 5W will get you plenty of QSOs on 20m SSB. 5W is fun.

A 10m version would be fun, but sadly is not available, but likely to be less useful in the years to come, apart from summertime Es. A 10m design would need better MOSFET PA devices anyway I think.

The BitX SSB transceiver on the QRP Kits website

http://www.qrpkits.com/ have some really nice kits on their pages these days. If you are new to QRP then they offer a very nice way to join in the fun. One example is the very neat version of the famous BitX 20m SSB transceiver designed in India originally. They also have plenty of CW kits and accessory kits like ATUs, attenuators and simple pieces of test gear. I've never actually built any of these kits but they look well designed with clear building instructions.

Scout Regen RX kit

Hendrick's QRP Kits in the USA have just introduced a nice little regen receiver kit for beginners and more experienced hams and SWLs. The Scout is a simple 2 band regenerative receiver covering from 3.5 -11MHz. It is based on the classic design by Charles Kitchin published in QST some years ago. It is to be launched at Dayton and on sale from May 12th.
