Just curious: Where'd you get the whip? Is it military surplus?

Yes, I got it from

http://www.american-milspec.com

They don't seem to have the same model now. It's a "folding" antenna with
shock cord holding the elements together for travel- kind of like the
poles for "dome tents". It was made for the PRC-25 and PRC-77.

I made a base out of some PVC plumbing parts, and put an impedance
matching transformer in it, and a BNC connector sticks out the side. The
bottom of the base is threaded with a 1/4-20 thread so I can put it on one
of my tripods.

I have a 30 foot run of RG-316e to connect the radio and antenna.

It takes about 2 minutes to set up or take down.

Mark do you have the + version. Mine has a three position antenna switch
on the back with a whip amplifier as one position so no transformer
needed. Maybe you found the whip still works better with the transformer?

1. SO-239 socket 50 ohms.
2. SO-239 socket whip amp.
3. connect to the high impedance terminals.

Hi

I have the plus version with the noise blanker and notch filter.

I have my radio set for the normal 50 ohm input because I've also added
the Avantek 30db amp. Frankly, if I find a nice quiet 15-20db amp
that'll fit I may switch it out, as I end up dialing in some attenuation
below 5mhz.

I didn't try the antenna without the transformer because I bought a box
of 100 ferrite cores a while back, and given how much they've helped
with my home antennas, I just automatically include one on every antenna
I make.

In any event, the whip works incredibly well, so there's not much
incentive to change it.

I've done a fair amount of experimenting with portable antennas, as
vacations and camping trips are a great time for me to listen to
shortwave - and this one outperforms everything else I've tried, and
it's at least as portable as the LF engineering Skymatch it replaced.

Need some advice from someone who has used either/both of these
receivers. I am about to buy one of the two radios and am having a
hard time deciding. The radio's I am comparing are in the following
configuration:

JRC NRD 545 D - Stock - ~ $1800.00

AOR 7030+ (Standard Filters 2.4, 4, 5.5, 9.5)
+ Noise Blanker and Notch Upgrade
+ 500hz Collins Mechanical filter
+ 1.0Khz Murata Data Filter
~ $1815

Opinions?

In either case that is a LOT of money for a shortwave receiver. Are
you really sure your listening habits require you to spend almost
$2,000 on one HF radio? Given that there are many high-end used radios
selling for a fraction of those prices, why not go that way. Chances
are you will hear exactly the same stations.

I have a 545 and I've been disappointed with it overall. I use my R8B
almost exclusively these days. I can't even remember the last time I
had the 545 on.
