Anybody out there building the new Hendricks Survivor SSB transcever?  Just ordered the kit, looking forward to building and using it.  Plan is a qrp field day, 10 meters during the day, 75 at night.

75M SSB QRP on Field Day?  Good luck with that...

I wonder if you can replace that one-turn Polyvaricon
tuning cap with a Ten Turn Pot and a varicap diode......
like you can with the BITX20A and the MKARS80,
both of which use the same tuning scheme. It's a VERY
simple mod, and I don't see it hurting anything to try it.
One turn tuning to cover 350 KHz is a major pain,
irregardless of that "Fine Tuning Pot".

I hope that your Survivor turns out well. Did you check
out the MKARS80 from RadioKits.uk before you picked
the Survivor? The MKARS80 come WITH an LCD digital
frequency display AND an enclosure, all for about $60 less.
(Though I haven't compared the two radios in "real life".)

The man is right, QRP SSB on Field Day is gonna be rough.....
Good Luck and have fun!

The club that I will be with operates QRP only on field day.  Campground on Cascade lake, fishing, boating, eating, adult beverages, and "ham radio".  Can't help but have fun.
As for the tuner, I will have to check that out.  Thanks, John

QRP SSB on 75..  Yes, I've done it and the club I belong to last year did it with
great success.   Pay attention to the antenna!  A tuner manual or auto is helpful.

Yesterday I was on 75m at 20W talking to people throughout New England.  Sure you say 25W, the antenna]
was 60ft of wire at about 3ft using bushes as support and a large rain spout as ground.  I wasn't loud but
I was heard.  Can you imagine what using a dipole at 40-50ft, or a good vertical with a bunch of radials
might do?

Oh, I nominally operate 40M SSB using a KNQ7A (10w) mobile with a 8ft whip.  If that is compromised
I don't know what would be.  It isn't a rock crusher but I was heard in mane and LI NY today
(from eastern MA).

Its' doable.  Nominally daytime ops will be weak, early evening (gray line) will be very good and night
varies.  I'd up for a multiband radio (or several monobanders) as any given band can be dead and
very boring.

Higher power is nice but carrying a battery to run that can be non fun.

Getting back to the OP, I came across http://eksfiles.net/building-the-kd1jv-survivor-75m-ssb-kit/ which you may find interesting.  It goes about 1/4 of the way through the build.  I especially like how Mr. Ek has divided up the build into testable units - something the stock construction manual doesn't do.
