I also am anxious to get the internal 2m option for my K3. I have to wait until i
return from Clipperton in March though, since my K3 has already been shipped. I
also am hand carrying my KX3 down there with me, so I will have two rigs for 6m.
I have a Mirage 2m "brick" that has taken a lot of abuse over the years. I also am
sure you would have success with a TE SYSTEMS amp because the K3 does not put out the
notorious power spikes like most of the ICOM rigs. I use a TE SYSTEMS amp with my K3
on 6m, and it works great. If you are looking for some more power that uses the
Freescale transistors, I suggest taking a look at the M2 2m amp.

I use their 6m amp on my 6m EME DXpeditions, and had it modified so I could drive it
to maximum output with under 3w so I could use it with either my K3 or KX3 when I am
on DXpeditions. I am taking this amp with me to Clipperton to use a backup to the
Alpha 8406.
The problem with the new high gain solid state amplifiers is that the FCC doesn't
currently permit 1kw output with a few watts drive, although it certainly is easily
obtained with the new solid state components. So if you are operating in the USA,
you would have to make the modifications yourself for low drive directly from the K3.

As one that has designed and manufactured SS HF, VHF, and UHF amplifiers, the
world in the last 15 years has evolved with many new devices that are really
bullet proof. However, I have not seen any on the market with the new
Freescale devices. I have designed and built several from 13 to 450 MHz for
industrial use in the 100 to 500 watt class. If you decide to build your own,
look up Freescale the gain these devices have is incredible. They have a
wealth of application information and evaluation PCB's available. FWIW.

If I were new to the use of solid state VHF/UHF amps I would make
sure I bought amps with protection for SWR and overdrive mistakes.
I use TE Systems amps with the K3 and XV432 in the shack, but as
others have said, be careful with any amps that have no protection
circuits. The cost of repair (if not done by you) can be as
expensive as a new amp with the protection circuits.
I think Mirage amps are good amps, but haven't had one since MFJ
began manufacturing them.

Does anyone have the K3 2-meter option and use a solid-state linear amplifier?
If so, which one. Also, maybe some information on the best to worst in
available 2-meter amplifiers as I have never looked into these before.
And, a friend suggested building my own 2-meter solid-state amplifier. Has
anyone done this and maybe I can hear a little about that too.
Thanks for any comments.
