After the overwhelming power of the Yaesu and Kenwood, in the amateur radio market in the early '80s appeared overbearing on the market for a new home, already active in Japan, but still long way to go on world market
Icom!
practically absent in the competition of the transceiver tube, here it develop and evolve with the transistor devices, gradually more and more interesting.
After having tried the bitter with the Icom IC-701, it was the turn Icom IC-720 and Icom IC-720A, compact apparatus and famous for his four conversions and a receiver for the noise it made when switching the band (hi).
Then continue with the evolution of increasingly sophisticated equipment, such as the Icom IC-740 and especially with the Icom IC-745, an excellent appears to continue in harmony.
But the explosion was yet to come, now Icom mother was ready to crank out a great little device: L 'Icom IC-751 and then the' Icom IC-751A!
still a reference point for all instru Ssion Icom, Icom 751A was a real landmark, famous for his extraordinary talent at receiver 4 conversions, perhaps a little noisy, but solid as a rock and capable of top performance in all operating conditions.
apparatus compact, 12 Volt 100W continuous line and, if 220V power with its optional internal power supply (which warmed quite a bit 'but'). Very aesthetically pleasing with its military-style livery and a big beautiful yellow color from the S-Meter, this gave the impression of what it is: A Warrior
frequencies!
Suitable for all operating conditions, both at home and around the DXpeditions, its combination crystal filters for CW and SSB, are still among the most successful, also has an excellent IF Notch filter and a good PBT.
as it was for the legendary Drake R4C, with a few keystrokes and a few knobs, but behind a great receiver, but the Icom IC-751A, could get you out of trouble of QRM, without pressing too many buttons or small buttons!
jewel born from this then the Icom IC-761 which is nothing but an Icom 751A in an outer shell, and with a heavy feeder el 'antenna tuner.
not valid unless its predecessor the Icom 751, which sostanzialmete has the same receiver.
Curious then that Japan was called the Icom 751 Icom 750 Icom Icom 751st and 750th, of course!
Among the most well-known problems, the battery unit of Ram, that if you get sent completely tilt the device, problem solved then replace it with a card type Eprom
Have a nice Icom IC 751A last series? Eye to the command IF-Shift!
How many versions of the Icom IC-751A were produced?
that I know of three versions were produced, one with the old Icom logo with "The" great, then two versions with the new "i" on the small logo.
For licensing and patent issues, the latest version of the Icom IC-751A that was worse rather than better!
fact instead of PBT, was fitted with a rudimentary IF Shift, if that was activated, dramatically worsened the quality of the receiver, as the filter of the media jumped fully frequency of 9 MHz!
This problem also applies with its contemporary, the legendary Icom IC-765.
Fortunately, with a semplicicisima modification (just unplug a cable!) Found on the internet, you can 'restore the original function PBT, as it was designed and also bring the latest series of Icom IC-751A to the splendor that is his due, one of the best devices ever built for hams!
I want it! How much?
Given that now is a radio that has 20 years of service and that those who have it if he keeps it tight, now find a good Icom IC-751A, is not simple.
Prices are fairly stable from 450 to 550 € for an Icom 751 in order. and from 550 to 650 euro, or even more if with an option for an Icom IC-751A. Bearing in mind that you have already performed the famous change in the battery.
