My portable HF kit is coming together rather nicely.  To go along with the KX3, I've got a 31' Jackite pole for antenna support.  I have a 88' doublet fed with 300 Ohm twinlead and a 20m dipole fed with 450 Ohm window line.  I tossed a short piece of RG-8x into the bag for use with my binding post-to-BNC adapter just in case I have issues with using the twinlead or window line.

I'm powering everything from a pair of 3200 MAh LifePO4 batteries connected in series to get 13V.  The LifePO4 batteries are rather light for the power they provide and can take a charge rather quickly.

I put up an Off Center Fed Dipole fed with some 450 Ohm window line using a 4:1 balun (rogertango.com).  I'm using 45ft on one leg and 90ft on the other leg.  So far, it's looking good.  SWR is low across several bands and it can hear very well.

Update:  I took the OCFD down and put up a loop.  I need to get it up a bit higher, but it hears pretty good.

I'm really liking the Elecraft K3, P3, and KPA500.  I've made several DX contacts (including TX5K) and am very pleased with the receiver and ability to locate signals with the P3 and external SVGA monitor.

The KPA500 is so integrated with the K3, it's like simply having a 500W capable radio. Turn it on and operate.  No tuning or worrying about band switches.

I'm so glad I went with this setup!

It's all assembled...  Started Friday evening and here it is midnight on Saturday and I've got my new K3, P3, and KPA500 all working.  Now to put them to use...
