po tak fachowych wypowiedziach znakomitych fachowców ceny FT2k
polecą na łeb,
a już nie są wysokie,
nadal nie wiem czy można na nich nadawać ?

FT2000 review up-date:
After long waiting and being patience I finally received my NS 3KHz roofing filter.
It arrived just one day before the start of the CQWW SSB 2010 contest.
Installing it was not a big deal..

The main receiver has improved tremendously specially in relation to strong nearby signals.
My test case was the CQWW SSB .. we had the following setup:
Band 20M
- FT2000 + home brew 4-1000 Amp
- 4 element beam 40ft boom @ 100ft

The 20m band was saturated with extremely strong signals. The FT2K preformed average to good.
The main problem was digging weak signals from the strong ones.. which may have been a problem with any other rig.
I’m still testing the FT2K using the NS filter.
I must admit at home the performance with the NS filter is very well., there is a significant drop of noise engaging the NS filter and the weak signals can be better separated from the side band splatter.
The DSP works better due to the less band with to process, in order the enjoy the full benefit I would suggest to play more with the VRF.

So generally I can say.. the NS filter modification is a must, pity that Yaesu never took their responsibility.
We had to wait almost 3 years for the first software improvements the filter flaw was never admit by Yaesu.
So if I have to rate Yaesu it will be 1/3
In my previous comment see below I rated the FT2K 1/5

Now with the NS filter I rate the FT2K 3/5

A FT2000 review on a small expedition.
The PA6Z DX and contest group went down to Luxembourg on a minor Dxpedition LX/PA6Z, the setup was as follows.
A total of 23.195 QSO's was made in six day's

Radio set-up:
- FT1000 mark V + Emtron DX2
- FT2000 + Expert 1K-FA
- FT2000 + SB220
- FT1000d + SB220
- TS950sdx + TL922
- TS950sdx + Alpha 99
- TS440s + SB220
Antenna set-up:
- 6M beam 6 element
- 10M beam 5 element
- 12M beam 3 element
- 15M beam 3 element
- 17M beam 3 element
- 20M TH6DX
- 30M vertical (elevated radials)
- 40M dipole
- 80M dipole
- 160M inverted L + extra beverage RX antenna's
The radio's where not dedicated to the antenna set-up.
All radio's except for the two FT2K's preformed FB one slightly better than the other.
The two TS950sdx radio's preformed flawlessly on CW and sideband, the FT1000d did an excellent job on CW, side band was okay not overwhelming.
The FT1K mark V worked averaged on both CW and sideband.
The TS440 was an average radio nothing special.

But the FT2K's (2006 and 2008 version EDSP 11.53 v1.49) preformed way below all the radio's.. on CW it was workable but on side band both preformed BAD.
We also noticed that both radio's where extremely sensitive for RF feedback.
Both radio's produced so much phase noise that we had to use two external band-pass filters in order to reduce the noise. On 50MHz the noise is uncontrollable when the FT2K was making TX all other radio's suffered from a S6…S9 noise level..
Working pile-ups using the FT2K is a real challenge.. where is was a piece of cake using the TS950sdx.
The FT2K's IF was completely overdriven by strong signals in a pile-up, so signal readability almost reduced to zero.
The audio HISS is an killer… after two or three hours listening you where exhausted.. on all other radio's except the FT1K mark V the long listen time didn't bother at all.

Summarizing:
The way the FT2K is these day's make here a NO go radio. I'm looking forward to the crystal modification of Jeff.
The phase noise is an serious issue if you have an neighbor who also owns a FT2K.
The audio HISS can be modified… and should be modified..
