One correction. The HF Packer is not a 50w amp. It's about 45w at 160m,
and then steadily less as you go up in frequency (40w for 80m, 35w for
40-20m, 30w for 17/15m, 25w for 12m and about 20w for 10m). It doesn't
support 6m. These numbers come directly from a graph in the HF Packer
manual.

Hands down the KXPA100. It isn't out yet - shipping in August but offers the greatest flexibility with a tuner and portability. The Hardrock is ~$260. It is only available to members of the Yahoo group right now. It is 160-6m and generates a solid 50w from 160-10, less on 6m. I own a Hardrock and it was a difficult build but Jim Veatch helped me out a lot - WA2EUJ. No tuner though so you will have to invest in a ZL100 or equivalent. The Elecraft tuner is faster and tunes a wider range. Size wise is only slightly smaller than the Elecraft 4 1/8 wide and tall by 7 deep. The TenTec is a larger amp - $800 plus a 100w tuner. The THP HL45B is a solid performer at about $450 from HRO. Again you need an outboard tuner. You have to manually switch bands. If you don't it will go on standby - a self protective feature. I played with a THP for a while and it works well. You can get one used - not easy - for about $250-$300. There are the RM Italy variants - beware do
no
t overdrive - IMD artifacts - HL300B is the model - only drive to 100W - I
have no experience with this amp. These are not certified by the FCC. Some
people have had great luck with the Juma 100w amp and some on the reflector may
have owned one or built one. The Jumas can be programmed to band switch with
the rig. Again - it needs an external 100w tuner.
So here are your choices:
Juma 100w - no tuner - band switches with rig automatic - FCC certified
Hardrock 50w - no tuner - manual switching - not FCC certified
TenTec - 100w - no tuner - band switching with rig automatic
HFPacker - 50w - manual swiching
KXPA100 - 100w - tuner - automatic band switching - FCC certified
THP HL45B - 45w - no tuner - manual switching (except for FT817) - FCC certified
THP HL100B - 10w - no tuner - manual switching - not FCC certified
RM Italy HL150 - 150w - no tuner - manual switching? not FCC certified
RM Italy HL300B = 300w - no tuner - manual switching? not FCC cerified
Antennas
Too many to list
Personal favorites - G0GSF- multiband dipole - 4 bands are OK w/o a tuner, EFHW
- cut to 45 ft with EARCI matchbox KX3 tuner will match 80-10m

While all these posts have good advice for a bc trip , I really just want the
KX3 amplifier. I have the other items already ( Delorme GPS plus SPOT with
rescue insurance paid up, sat. phone rented , several 2M HT's ( APRS godd idea
, I'll add that ) and the usual flares , panels , noisemakers and things that
go bang ) .
But...I need an amplifier and the right antennas to add to this.
We will be doing the check in via SPOT , sat. AND am. band.
SPOT loses lock in jungle and mountain ,vso do sat. phones and GPS.
Certain unfriendlies like to jam their freq's as well.
In addition to that any or all that gear can be broken , lost or confiscated by
certain sticky fingered locals ( it.s happened ).
Hard to jam 6M-160M all the time though.
I am not "shouting in the dark" for rescue. We have several pre-planned
operators standing by with preplanned times and frequencies and backup frequencies.
But, they are also mobile or may have interference so I want the best chance at
a clear signal both ways.
There are no repeaters out there.
This is in Africa.
Please , any KX3 amplifier advice ?
Ten-Tec , Hardrock , etc. , which specific models with setup/operating tips ?
Greatly appreciated !

HT's have GPS and with APRS one can send messages. I have used it on hikes so my wife can
track me on the internet as I hike. The HT sends a beacon signal out and the movement can be
tracked through APRS.fi Any Ham can get an APRS account. I have even used APRS on my
iPhone for the same tracking capability. Remote from civilization though you would need an HT
with APRS like the VX8R by Yaesu or a TinyTrack tracker. With the HT however, you can call for
help and the reach can be substantial depending on elevation or having a nearby repeater.
Having worked 45 states on Field Day just using a KX3 and a G0GSF dipole, I have no qualms with
getting out and reaching people with a KX3 on HF. When the 2m module gets out - I have a
complete package for all modes of remote operation.

That's what I'd do as well. Some personal locators will send an "I'm
OK" message, too to designated recipients. And, if you don't want to
buy a personal locator... you can rent them, which might be less
expensive, if it's a one-time trip.

I love amateur radio.
However, if I was living 200 miles from the nearest real town, I'd
invest in a good Personal Locator Beacon (or two) . The kind with a
built-in GPS.
Sure, it's not "communications" but it's a one-button "come get us,
we're right here" and the Search and Rescue Satellites are quite good.
I keep mine in the car.

experience
?Thanks in advance.
