Dan--Well I have had the PRO III approaching two weeks now so as promised here are some first impressions. I feel the PRO III is more evoluntiary than revolutionary. Having said that do I feel its an improvement over the PRO II ?? No question in my mind that it is a better radio--and I had my PRO II for three years. So where are the improvements? Most noticeable is the display. You can now show three or more parameters at one time. The top third can show operating frequency filter width--Dsp settings etc plus local and UTC time. The next portion can show spectrum scope data--while the lower segment can show filter setting or digital meter or?? Really keeps you informed.The reciever seems to be quieter than on the PRO II-dont know if this is due to the new roofing filter--the low distortion BPF switching or what but it is an improvement. The new Pre-amps seem to allow the signal to come up without dragging the noise floor along. The NR seems to be more effective with less distortion introduced. The NB finally seems to work. While I havent tried it as yet the PRO III does have the 60 meter band available. I have recd excellent audio reports on transmit--using a Heil Goldline in the wide position and a number of the stations have remarked the audio seems louder-dont know why that would be. You can now adjust your SSB transmit bandwidth for both the high-pass and low-pass edges in addition to stting the Bass and Treble points. It will be inetresting to see the first test results to see how close Icom is on the Third-Order-Intercept figur of +30dbm, Anyway thats some prelim observations on the PRO III. I feel Icom has another winner.     de John WB0SQZ

 

Dan, just wanted to drop you a line to tell you how pleased I am with my Pro III. I was very apprehensive in trading the Mark V in for the Pro III, but I made the right decision.
 
Here are my thoughts of the the Pro III.  Of course the first thing that stands out when operating the Pro III is the large display. Its nice to be able to monitor your signal in the transmit mode with the scope, For dx the recieve scope is great. I was working on 6 meters last week and I worked stations that I would never have found if I hadn't had the scope. It really can help you with weak signals or when you think  the band is dead. I also like having the multi meter on the display as it shows swr, alc, po,comp, and signal strength. With the new mini scope you can place it on display as well as meter function.
 
My transmit audio reports are better on the Pro III than the MarkV. The setup for audio is very easy. After  adjusting the  bass and treble in the menu  which took about 5 minutes, I was on the air and had great audio reports from my buddies. I run  a sm-6 with my mic gain and comp at 9 oclock with ssb set at wide comp. I recieved many compliments for  sounding like myself.
 
I am really pleased with the reciever of the Pro III. I like it much better than Mark V. For many different reasons.  The recieve audio is very crisp and clear and I continue to recieve weaks signals as I did with Mark V. The NR   noise reduction is much better than the Mark V. At times I have power line noise  up to a s-9 and with the NR I can bring out the voices which I couldnt do with Mark V. The filters are wonderful. Im still amazed as to how well they work. Just turn the twin PBT to adjust your width and WOW the adjacent splatter is gone. Preamp seems to work fine with little noise.
 
I have transmitted rtty and recieved it with decoder and works great. Its nice having the cw memory keyer as well.
 
The automatic tuner works better for me than the Mark V. I run a homebrew 4-1000 amp without a tuned input circuit. The Mark V struggled and took time to tune to this amp but the Pro II tunes to it in about a second. Its amazing the difference.
 
I hope this might help someone who is contemplating  purchasing a Pro III.  In my book its a winner.
