Hi All and thank you for your replies.
First a little back:
I have been a Ham for over 35years and in that time have owed many many radios.
The LONG AND SHORT of it......, I know what I am doing.
So..........., I have so knowledge.
I am using the same base antenna in all my comparison in FM mode.
I have tested with, and without the pre-amp.
From what I am hearing here on the forum their must be something wrong with the radio I have.
Just an example. A signal on my FT-7800 or my FT-2800 will show and s-10 and be very readable. On the 7000 s-2. And almost unreadable.
I have to sit in front of my house with 35 watts for the 7000 to see a 40 over signal. This holds true for both VHF and UHF.
So something is not right.

P.S. Please......,No green horn questions.

Can you be a little more specific on how the 7K falls short?
I have an FT-8800 and have compared it to my 7Ks, both on the air and on the bench with an Agilent 8924C analyzer.
On the bench, the 7K has better sensitivity than the FT-8800. The 7K has 12 dB SINAD at -125 dBm (Preamp ON), while the FT-8800 is at -121 dBm for both VHF & UHF. The S-meter calibration for the 7K is S9= -84 dBM for VHF and -91 dBm for UHF(preamp ON) versus -91 dBm for both bands on the FT-8800. The 7K is meant to be used with the preamp on.
In a strong signal environment the 7K is less susceptible to intermod than the FT-8800, especially if you turn the preamp off on the 7K. The FT-8800 doesn't have an switchable input attenuator or preamp.
I work weak signal SSB on 2M and 70cm with the 7K with good results.
For public service events I use both radios side by side and in the fringe areas of repeater coverage on long bike courses the 7K has slightly better reception than the FT-8800, but most of the time I can't tell much difference.

High again all.
I was wondering what your thoughts were about the IC-7000's VHF/UHF mode.
I find the receive performance on both bands to be very poor.
I have a FT-7800 that just blows the 7000 away. I have also compared it to other vhf/uhf radios and the Icom falls very short on the receive.
What is your experience with it?
