[ICOM] Icom 740 vs 751A

Sat Mar 31 18:45:33 EDT 2012

John, I am sorry, just read your question. Here is my thought process. While the 740 was very good and the 751A was great there is the concern that you may not be able to find the appropriate parts to fix these old radios as ICOM no longer stocks many critical parts including critical IC, etc. The 746 PRO was outstanding and had 35 filter positions so you would never buy ANY filters and they worked really great! When I saw the 7410 this was my chance to upgrade so I could avoid the back lite issues that the 746 has even though i never had an issue. I sold the 746 PRO for $1000. I bought the 7410 on sale at HRO around Dayton weekend for $1600. That was a no brainer for me. I have not had any issues with the 7410 and it is light years ahead of the PRO with the DSP chip and features which is the same as on the 7600 and higher series. Now it is learned that the 7410 and 9100 can accept firmware upgrades so my investment is completely protected. I run my
 7410 with the Heil PR 781 mic and the Palstar SP-30H speaker and I have a winning combination. Good luck, Gil

John: Receiver performance is a very subjective thing. A good performing receiver to one person my not be good to another. For example. For cw contesting, performance at 2 khz may be very important , whereas an ssb operator knows that a strong station 2 khz away is going to have 3rd and 5th order splatter products anyway.Sensitivity is likely not an issue on any modern receiver, but frequency stability and  PLL phase noise might be.Most knowledgeable hams know that a noise blanker is designed primarily to reduce inpulse type noise whereas a DSP noise reduction may resuce some of all three types of noise. You may want to study and garner information from various sources so you can make the most informed decision that best suits your type and style of operating.

Hi Gil,

How did the 746PRO compare to the 740 and 751A in terms of receiver 
performance?

I owned both the 740 and the 751A each for 10 years. The 740 was a great 
radio but the 751A was far superior in almost every aspect and was one of 
the best transceivers ever built. I then had a 746 PRO for 5 years and now 
have the the 7410 which by far is superior to any of these radios in every 
aspect.
go to http://www.eham.net/reviews/products/14 and check the reviews:

751a a perfect 5.0 with 94 reviews
740 is a 4.6, 30 reviews

Good luck, Gil

The two rigs are pretty much on par but the 740's receiver is perhaps
even better than the 751A because the 740 is a HAM-bands-only rig,
while the 751A provides general coverage. The rest is pretty much the
same. The NBs are just so-so.

If you have an experience with more modern rigs, it will be quite
annoying to see the 10 Hz tuning step and absence of computer control.
But everything depends of your interests, of course. Still, the 740 is
famous for its incredible receiver, first of all, due to its
outstanding sensitivity.

73,
