K3S Semi firm plan

Ok, based on current funds the purchase at Shelby will most likely be as
listed unless there are further discounts. I've asked and they don't offer a
veteran or masonic discount.

Purchase/Order:
K3S/100-K 100 W Transceiver, Kit
KRX3A-K High Performance Subreceiver for the K3S and K3 Kits

* Already purchased a 400hz filter from a reflector participant.
Other - Dust covers from Rose for Rig and Bencher Key.

Future:
Another 400hz filter
Pair of 200 or 250hz filters* I want to operate the rig for a while to see
what I actually want/need.
KAT3A-K Internal ATU with 2nd Ant. Jack for the K3S and K3 kits ** not
really sure I need this as I only plan to use resonant antenna's, we'll see
how sensitive the rig is. I've been told it will back off on power as SWR
rises.
P3-K Panadapter Kit for the K3S, K3 and other rigs ** for the time being
I'll use an SDR to view the band
Misc filters over time as needed.

LOL, I'll be broke for a while but on the air.

Re: K3S Semi firm plan

I've noticed with my K3S when operating with a SWR of greater than 2.5 :
1 the power output does take a dive downward. While I use an external
tuner, it would make sense to have and use the internal ATU in certain
applications.

While resonant antennas are best, I operate 160M and 80M and due to the
bandwidth, some means getting SWR to reasonable value across the band
sure seems reasonable. I find the internal tuner does and excellent job
resolving a match with these bands.

Re: K3S Semi firm plan

The power reduction you see is sometimes called folding and is done to
protect the final transistors. An assessment of the antennas you have or
contemplate with their SWR curves, and whether you will be operating
barefoot or not should tell you whether tuning will be required.

Some will want to handle the tuning chores with a high power tuner that
will also do this for a transistor external amp.

For example a K3, KPA500 and KAT500 would not need the tuner in the K3.

If you expect to use your K3 at a field day, get the KAT3.

If you get it and never use it you can sell it in a heartbeat here on the
reflector.

Another of those very individual decisions.

Re: K3S Semi firm plan

In reply to this post by Bob McGraw - K4TAX

Cool. I have an external MFJ I can use. I just don't have the cash for it
all. Just the 100w rig and sub RX is $3250 and I've already paid $80 or so
for the 400hz filter from the reflector.. If I had the cash I'd buy the full
setup stuffed with filters..etc..

The current plan for 160 is probably going to be a mag loop and a separate
one for 30m. Right now my priority is 40/20/15 and/or wherever DX is.
I'll definitely be posting /sharing my experience and first impressions.
I've not seen a K3S build video so I may even take a vid or 3. ;)

Well if anyone has the options for sale please PM me off or on list.
I'm interested in the subrx, filters, atu, ..etc..
