<As others have already said, FCC approval does not apply to imported
<amps. That's why you could purchase Emtron's DX-2sp, DX-3sp, and DX5
tetrode amps. The gain was not limited as is the gain for the OM amps.
IOW, you could import a 10 or 20 KW band switched amp with 20 plus db
gain, no questions asked. This gave us the ability to purchase a manual
tuned amp with enough overhead to run digital @ 100% duty cycle. Of
course that overhead also gave the ability to run 2.5 to 3 KW PEP.
The only caveat is they have no US based sales outlets.
The gain limit has long been outdated as the reason for it has not
existed for decades. Will the FCC ever get rid of limiting the gain of
separate amps? Recently there were letters of comment that were almost
irate about removing the gain limits. Apparently those hams are still
living in the past. The same can be said for amps being sold that
require hams to modify them to cover 10 meters.

## check out the OM-4000 on OMs website.....vs the ...FCC approved
version of the same OM-4000 sold by array solutions..on the AS site. The
real deal
OM version the factory sells is rated at 4.5 kw out. The ...FCC approved
version
that array solutions sells is rated for 1.5 kw out..and has an attenuator pad
on the input.
Being cpu controlled with a freq counter built into it, it also wont TX on 11m
and freeband, only
24.880 to 24.890 and also 28.000 to 29.700. It wont work on the 30M band
either...
10.1 to 10.150. it will also shut down if it sees the drive level input watts
exceeding XXX amount.
## so it looks like there is some fcc rules still in effect to have to make
that OM-4000 amp
compliant, to be sold in the USA...AT A US DEALER. The palstar 3 holer was
export only.
I asked palstar about this a few yrs back. They would ship the 3 holer to a
usa address,
the idea being I could pick it up across the border, 18 miles away. However,
zero problems if
it was shipped outside the usa....and direct to my home address.
A buddy of mine in Nevada wanted the 3 holer real bad. The only way he could
get one was for me to
buy it for him, have it shipped to my home address, then re-ship it back to
his home adress...which is
perfectly legal.
## The rules are for US dealers shipping to US address’s...then it has to be
....compliant.
## Anything the US ham imports directly from outside the usa is legal, you
can buy anything you want.
On a similar note, that 4Z4 ham who sells the SS kw amps on ebay, also sells
a 1.5 kw monoband version
for 12 + 10M. And another kw SS amp that sez its for 11m ! The 11m
monoband amps, may or may not
contain a LP filter.
