Author Topic: very small qrp ssb rigs?  (Read 10963 times)

While my search for a Mizuho MX-18 S continues I am wondering if there are any super small (backpack friendly) qrp rigs that will work on 17 meter ssb? Looking for something that is 'grab and go'. I am considering the new Argonaut VI but it is just a bit large for what I am looking for. There seems to be a fair amount of qrp rigs listed in the eham reviews but the small ones I have read about seem to be cw only and the ones that do ssb such as the MFJ rigs do not offer 17 meters.

You may be interested in the 17M version of this kit.

The Mizuho rigs weren't all that common--most folks felt the normail retail prices were too high compared to what you got.

Currently two choices...  Both good ones.

ELECRAFT KX3

Yaesu FT817ND (or a used earlier plain 817)

There are few 17M SSB radios in the small catagory.

MFJ makes the 9417 17m SSB radio. Not sure if that is too large for you.

Very easy SSB kits from Spain!

Save for the Iler is only available for 40 and 20. 

The poster asked for 17M, that doesn't answer the question.

The 20M version could be modified for 17m, if the builder is up for it.  Then again there maybe
many other that could serve as a base for a 17M radio...  Not a great answer but it does speak
to the choices avalable.

I have no experience with them, but the TJ2B MK2 5 Band SSB Handheld Transceiver from youkits.com looks interesting.

I was calling CQ a couple weeks ago on 20 meter SSB when I was answered by someone using an X1M.

His audio was a little thin but signal was great. I checked out the rig, it looks rather impressive.

He said the microphone was cheap so would like to see if I could work him again if he got a better mike on it.

Cool looking rig. I think they run around $300

My Elecraft K2 only weighs a  couple of pounds, and is actually quite small and easy to carry. There might be smaller radios out there, but its performance is superb. The new Elecraft KX3 would be my choice for a new qrp radio these days, but I already have the K2. NOTHING out there will come close to the KX3 for features, performance, and small size.

Lane :

Unfortunately I sold my MX-18s a few years ago. If you can't find a used one then
the 17m BitX17a kit from Hendricks QRP might be your best bet.

I have the BITX20A and it's really sweet, especially with the
varicap/ten turn pot tuning mod, which is super simple.
I'm sure that mod will work just as well with the 17m version.

But I am not certain how truly suitable for backpack ops a BITX is.
There are a lot of hand wound ferrite inductors and transformers.
These can be attached to the PC board with hot glue or whatever,
but still....I wonder. Even carried in a nice padded mini Pelican Case, there is always
a lot of jostling about while hiking & climbing, and in packing and unpacking
every time you setup camp. I could very well be wrong, I've never tried using
my 20m BITX backpacking. Too old & feeble, my portable field ops
are out of a tailgate or a "drive in and park" camp site!  Grin

Re: KU7I

  I wouldn't worry about using the BitX17 for backpacking, most all these small rig's coils and Xfmrs are only held in pace by the soldered leads themselves and if the X17 is only half as rugged as an MFJ Cub or Weber Tri Bander carried around in a small semi padded camera case then the only real concern is not tripping over the feed line at the campsite and flinging the rig into the campfire or nearest tree, shit happens.

The BITX would be a perfect candidate for redesign as SMT KIT. The design could easily be broken down into a set of vertically stacked PCB's that could be screwed together
on long threaded rods. All these PCB's could be dropped into a box like a HF manpack radio. This is how the manpack radios of the 80's were designed.  This rigid stack of PCB's would make the whole radio very stable and strong. The BITX would be the ideal experimental homebrew manpack  platform.
