New To Radio / Best Prepper Mobile Setup
« Last post by Drls on July 12, 2019, 06:18:14 AM »
First off... amazing resource.  Iím very excited to have found this community!

After reading these posts, I am interested by two systems most for their portability, low power consumption, and range.

1.  https://www.lnrprecision.com/mountain-toppers/

2.  http://qrp-labs.com/qsx.html  (Comming soon?)

Being able to communicate hundreds of miles on a few AA batteries is nothing short of magical.
I would love to see something like this in action, or learn about other similar systems that may fit the bill.  If anyone has something like this on Long Island and is a member here please message me and I would be so happy to see a working set up.

I would be happy to build as a kit as well, as Iím very hands on.
Looking forward to your thoughts
Thanks again!

Gents,
I tried the 9:1 UnUn with a random wire for field day.
While I made a dozen or so contacts, I was hoping for a little bit better.
I recently purchased the buddipole but haven't used it yet.
JHere is a 20second video of my field day. Look at the location and let me know if you guys think a buddipole would work better.
I was doing FT8 at the time of this video.
Cheers!

When will QSX be available?
We don't have an exact date, it depends how long it takes to finish all the above features and manufacture it etc. *Hopefully* something like November 2018, but this could change. Any updates will be published on this page.

Update 25-Jan-2019:
Development continues, progress is being made but there are a lot of details to take care of. Still no update on projected completion dates yet.

Update 05-Nov-2018:
We have some delays due to poor health, see https://groups.io/g/QRPLabs/message/27851 - recovering nicely now so will make more progress soon and update on this page.

Regarding the last link in there ó I wish Hans Summers the very best health recovery!

If the QSX kit wasn't coming out, presumably soon, I might have bought one already.

The thread about that one: http://radiopreppers.com/index.php?topic=1507.0
[Ö looks interesting - QRPlabs QSX all mode, all HF bands, 10 watts - $150 !!!!]

I finally got my Elecraft K2 on the air. :) Long story short, I bought it pre-assembled / used back in March, but when I tried it out I only got static. The radio is in mint condition, so Iím not sure if the original builder/seller ever got it working.... For a while was stumped, and regretted purchasing it. So I concentrated on getting on the air and making QSOs with the QCX transceiver I assembled.

My Elmer, Ken, took the radio into his shop and correctly diagnosed and repaired all the problems. He used calibrated test equipment to get the radio correctly aligned. All I can say is WOW. Itís so quiet and can pull out the weakest signals from the background noise. Ken showed me the K2 alongside some of his high-end rigs, and the K2 was just as quiet and had just as clear of a signal. The K2s a pleasure to just leave on and listen to. Although I still really enjoy the QCX, going from the QCX to the K2 is a bit like going from a 2-stroke moped to a Rolls Royce, at least in terms of noise.

Here is the battery I picked up from getfpv.com.  I had to buy the buy the battery tester / voltage alarm off amazon.com.

Got any good ideas on how to hook this up to either a 320 or351?  Is 22.8 volts enough to power the radio?

Thanks as always in advance
