ATS-4B nearing completion

After an easy 2 hours this afternoon the only parts left to be installed on my ATS-4B are the inductors (already wound), jacks, switches and push-buttons.

So far everything is going well. There have been only two typos in the instructions (both minor and easily figured out) with answers confirmed via the ATS Yahoo Group.

I can’t help but be repeatedly impressed at Steve’s design and efficiency. Way back when they were first introduced, I built an ATS-3 so I do have some idea of what this rig will be capable of when finished – 5 bands, 5 watts and a weight measured in ounces. It just amazes me.

As I build this tiny contraption, I’m doing a bit of reading¬†about early radio efforts that paralleled (but greatly differed from) Marconi’s spark gap mentality by a team of Canadian-American-Swedes and their accidental discovery. What a contrast.

One more session at the soldering iron should complete this rig, though I’ll probably stretch it into two to prolong the experience.

Minus the above-mentioned parts, here’s the rig as she looks at the moment:

    Very neat construction John. Looking forward to seeing it completed and of course, to hearing what DX you work with it!

    Good morning John, I have yet to tackle a kit with surface mount components but that day will come. Looks great and looking forward to the review as to how it works.

    Looking good, John. I am sure you have another winner on your hands. Wish you many years of fun and good contacts with it. I envy your building skills – SMT and I have not had a friendly relationship.

    Dave, I just hope it works when power is applied w/o the need to tshoot…always a possibility with (my) SMD soldering (so hold your compliments, Larry!).
    Mike – it’s your next logical step after all the Elecraft products you’ve built. You should consider one of Steve’s (KD1JV) upcoming dual-band SMD kits.+
