I owned a 751A some years ago and have always kind of regretted letting it go. Recently I bought a 718 and have enjoyed operating it, but when I sent it to have the cw/ssb filter installed I picked up a really nice 751 just to be my back-up until the 718 returned. Well, while waiting for the 718 I spent quite a bit of time with the 751. Long story short - the 718 is now my back-up! I love the receiver, low noise floor, up front simplicity and enjoyment in operating. I hooked up the MFJ 410D keyer and it works great. One of these days I'll get that PIEXX CI-V rig control board installed - but don't miss it all that much anyway.

What a great piece of vintage technology from Icom.
Outstanding receiver.I live in a noisy environment and was about to quit the hobby when I got my hands on this gem.Cut trough noise like a knife in butter.If it ever fail,I'll pay the money for the repair because it worth it.
Will I buy another one ? Absolutely!!

I have own many and many TRX during my electronician life , the IC-751 is solid , stable and perform well without problems.
IC-PS15 supply very solid also , the twin do not heat even light morning to evening.
Audio is great TX and RX with external large loudspeaker .
Any dynamic , crystal or ceramic microphone work WELL with only one FET transistor and one resistor into source about 1000 ohms to adjust for +5V at drain (+//5 microfarad if low Z as HC5 for exemple to increase gain) , no more needed , drain directly to hot wire "mic" and cartridge directly to gate.
Long life RAM battry , (firs 12 years .!.) and no problem to replace it.
Some units have had drift into last cristal mixer (pass band) but very easy to replace .
If curious problem occur do not forget to verify securely all screws to have good ground contacts at all PCB boards including PA , most problems are there so add one small drop fuel or motor oil at each screw (no more !)

All in tittle ...not so easy to operate that moderns rigs but very solid and perform well , I own one since long time .
Small problem into last series and IC751A : the cristal not very stable at 4th mixer but it is synthetic cristal genuine mount. Replaced by good cristal from DELOOR/DELCOM : no problem.
Battry RAM 10 years and easy to replace , if battry fail just return small card to reprogram , not expensive , or replace by non volatile RAM also not expensive.
Good audio receive and transmit and still better if adjust 3rd mixer cristal , very easy to make !
No difference with IC751A witch have just one filter more on main board , the rest is same.
I regret stupid RIGPIX comments about battry replacement , there is really no problem .!.
Long lasting Radio .

I have two 751's and 1 751A. All have been very good radios. When I bought the first one, I thought I had goofed to find that it had battery ram. But there are several good articles on the web for battery modifications, so this is not a worry. Also, I think non-volatile program chips may be available. Meter lamps can be replaced with LED's. As good, all-around transceivers, they are hard to beat.
They were not designed to be interfaced with a computer for remote control as are most current rigs.
Just a small correction to my review. The 751 and 751A were designed to accommodate an optional CI-v interface to allow them to be controlled externally by a computer, but they are not common and do not normally come with one of these rigs.

I am a relatively new ham with only 6 mo.s as a general, so my opinions are froma newbie's standpoint! I also have a Yaesu FT-897 so My comparisons will be mainly with that. Briefly for an almost 20 year old radio this thing really performs quite well. Many contacts have given unsolicited good audio reports and the receive is at least as good as my 897 with the DSP on. I have no options or mods on the radio other than the wideband mod. and the built in PS. I love the layout of the control panel. A button for everything. Much nicer than the menu driven 897! Compared to most radios today this thing is built like a tank! Of course it's as heavy as one also:) My only concern with the rig so far is getting the ram board from Piexx before my board's battery runs out. So far I have not worked any CW or digital so I'll have to wait on reporting on that. I do notice that with even the stock filters I can isolate individual CW transmissions fairly well when things get a little crowded.
Considering that I got the rig w/PS, an Icom H8 mic and a Diawa tuner all for $350 I think I did quite well.
I would have loved to have gotten a 751A but considering I am a nocoder and poor at the moment it is't that big a deal. I would love to be able to do A-B testing between a 751 and a 751A to see if the A is really that much better. I think if you're mainly a voice op the answer would be no big difference, except in the PRICE!!
In closing at least from my experience I think that the 751 has gotten a bad rap here. For a new ham on a limited budget this thing rocks.

I had an original 751 back in 1983 and it was HORRENDOUS! Riddled with RF feedback & going into TX for no good reason, shoving sproggies out everywhere the only way to stop it was to pull the power!
I've had a few 751's through my hands in recent times (2004-2008) & Icom seem to have corrected most of the problems so when you get a good one, you get a VERY good one BUT BEWARE! There still seem to be the odd one or two about which will scream with RF feedback if you push the mic gain that tad too far. Usually easily sorted with a couple of 0.01's and ferrite beads in the mic, the problem can be more stubborn, especially if you try to use a non-Icom mic. My advice is DON'T!
The IC-751 has a very capable RX and a TX with finals running well within their maximum rating. The PA kind of jogs along when it's easily capable of sprinting all day long! One error IMHO is the usual too-wide filter in the FM IF. I ALWAYS change these from a MURATA CFW455E (15kHz) to a CFW455G (9kHz).
The display may suffer the odd electrolytic dying and there was a missing earth link problem in early sets. The attenuator relay is prone to stick, making the rig deaf and the FM board relay can stick too, leading to low FM TX power. Servisol works wonders here!
If you're not afraid of a soldering iron and have a bit of savvy where wirelesses are concerned, the 751 makes a fine business rig which may require a bit of tinkering to bring it back to top performance. If you are a bit uncertain or perhaps not as dextrous as you once were, get one from a reputable source.
The IC-751? I recommend it, as long as it's behaving itself!

Well purchaced this as a non runner with faults.Spent a good month in the shack in the evenings fault finding as a project and replaced a whole lot of parts.Very inexpensive to sort out but after replacing all the electrlitics and some fet's , rl1 on the connecter board and swithching transistors in the rf sectiion this radio has come to life and i must say that the receive is outstanding with great on air reports a real joy easy to use

This was a bad radio and quickly replaced by Icom. The QSK was too slow - the DC to DC converter for the display would blow up frequently... There were a lot of low-level birdies in the RX... I think it didn't have the keyer that the A model had (It's been a while). The pre-driver stage had a tendency to oscillate taking out either the transistor or a pin diode. The rigs RF performance was great... it was just not as reliable as most Icoms I've used. The "A" model addressed all the issues as well as a quieter synthesizer.
