The new IC-7700 is a self-contained, top-performance HF/6m transceiver closely related to its 'bigger brother', theIC-7800. Its main features are:
Two independent DSP units.
One DSP (TI TMS320C6727B) is dedicated to the transmitter and receiver, and the other (TI TMS320C6720B) to the spectrum scope. These are of a later generation than the TMS320C6713 used in the IC-7800.
HF/6m transmitter with a MOSFET PA delivering 200W output at full duty cycle.
The PA utilizes a pair of MRF150 MOSFET power devices.
The new Rev. 12/13 PA employs a single ST Micro STAC2942 output device.
Quiet, built-in switch-mode mains power supply.
Single HF receiver with I/Q second mixer, offering +40dBm 3rd-order intercept point*.
The single receiver should be seen not as a disadvantage, but as a plus. The single receiver allows no-compromise RX performance at a reasonable price; BNC sockets on the rear panel, and CI-V, allow easy connection and synchronization of a second Icom transceiver such as the 756Pro3 as a secondary receiver. Many prospective IC-7700 buyers already own an IC-756Pro3. Add the IC-7700 to your existing Pro3 for the perfect contest station; use the IC-7700 as your main transceiver, and the IC-756Pro3 as a spotting receiver.
Upgrade from your IC-765 or IC-775DSP, and get the benefits of a spectrum scope.
The built-in tracking preselector, and relay-switched front end, offer unrivalled strong-signal HF performance.
Built-in high-speed automatic antenna tuner.
The tuner covers the HF and 6m bands.
Selectable 15, 6 and 3 kHz roofing filters (refer to Fig. 4 above.)
As provided in the IC-7800. The filters are optimized for lowest IMD. Each filter is mounted on a plug-in daughterboard.
Precision OCXO with ±0.05ppm frequency stability and 10 MHz Reference I/O jack
The precision OCXO with 10 MHz REF I/O allows the IC-7700 to clock other equipment, or to be clocked from a higher-level master clock source.
7' color TFT LCD display.
The display includes a simulated analogue multi-function meter.
Rear-panel VGA socket for external video monitor.
Multi-function spectrum scope with configurable resolution bandwidth (RBW).
RBW is configurable by selecting scope span and sweep rate.
The adjustable RBW permits spectral analysis of received signals. IMD products and spurs can be displayed.
Fig. 6 is a typical scope screenshot. The green trace is the real-time spectral display; the blue trace is the peak-hold display. Note the low 'grass' level in the absence of signals.
Built-in RTTY/PSK31 modem requiring only a USB keyboard.
The built-in RTTY/PSK31 modem allows use of the IC-7700 as a complete digimode terminal, requiring only a keyboard. This is great for semi-portable operation (e.g. Field Day) or when shack space is at a premium.
IF-DSP notch filter with adjustable parameters.
The notch filter shape factor is selectable in 3 steps, and its maximum stopband attenuation is 70 dB.
Multi-function noise blanker implemented in DSP.
Separate, high-performance 6m receiver front end.
Digital voice recorder.
Front-panel USB ports for USB memory drive and keyboard.
The USB memory drive socket permits use of pocket USB memory drives. No CF card is required.
* at 50 kHz test-signal spacing.
User Manual Erratum
Contrary to the statement on p. 3-5 of the earlier IC-7700 user manual, the numerical keypad is not backlit and does notlight when theF.INP key is pressed. This has been corrected in all newer editions of the manual, from ENG_1 onwards. The correct procedure reads as follows:
Download the Ver. 2.20 upgrade and accompanying manual here.
This upgrade was released on 21 May 2015.
Note: All versions of the IC-7700 are upgradeable to Ver. 2.10.

Watch my IC-7700 Ver. 2.0 Firmware presentation at Dayton 2014.
Rev. 12 IC-7700:
This IC-7700 version was released in April 2011. It incorporates redesigned PA200W and FILTER Units. The new PA200W uses a single STMicroelectronicsSTAC2942B dual MOSFET power device in its output stage. The serial number prefix begins with '1' e.g. 1201234 (US/Canada), 1301234 (EU), 1701234 (UK).
The previous serial number ranges begin with '0' e.g. 0201234 (US/Canada), 0301234 (EU), 0701234 (UK), and have the earlier PA200W (2 X MRF150) and FILTER Units.
Q: Why was Dual Watch omitted?
A: Provision of Dual Watch would most likely have pushed the price well above the USD 6K target.
Q: Then how can I monitor my transmit frequency in split operation?
A: By pressing the XFC (Transmit Frequency Check) button.
The IC-7700 received FCC certification onFebruary 11, 2008. FCC ID: AFJ300900

Still top of the line!
Time owned: more than 12 months
Have had the 775DSP for some time now. It truly performs well past some of the current models out there and equally well, if not better, then some of the models now selling for 5 figures! It is a big radio and not prone for portable operation. Mine has all the filters in it. One nit for me is the antenna tuner. When I use my outboard tuner since I have an amp in line, the radio's tuner kicks in when I try to tune the SWR. It is hard to get it now to kick in. Nice feature, but since I am using an amp, I am forced to use an outboard tuner for the amp's sake. I love this radio. Ergonomically, it is one of the best. If you have the chance to get one, do it. They are hard to find and not many were made!

Excellent device
Time owned: 3 to 6 months
I have owned most of the Kenwoods, Yeasu and Icoms. The 775DSP is in a class of its own. This radio is awesome on receive and is better than any other HF radio I've ever used. Audio TX with W2IHY eq is outstanding.

A Competent performer all round
Time owned: more than 12 months
Well where do we start, I have held fire on writing this review for some time. At present I have an IC-781 and IC-775DSP and in the recent past: TS 870, IC756-P2, IC-746P, IC-7400 and have owned and tried many more. My ic-775DSP has all the filters including voice chip and high stability crystal oven plus the rarer 6kc AM SSB filter and rack mounts. 1, The second VFO should be tuned to a redundant band as there is miner breakthrough, I do not consider this a big problem for me. 2, TX over shoot and unsuppressed carrier.. When using an HF amplifier .I have used two amps so far ,one uses a single 3-500 and the other amp uses a single gs35b triode. I have had a slight problem so far after 18 months constant use …with unsuppressed carrier. Note I do not use CW…just SSB…but there is a sign of unsuppressed carrier… carrier suppression was checked and is now up to spec minus 45db .I consider this to be a slight problem, it would depend on mode and gain of your aerial and proximity of other hams .TX over shoot regarding tubes no problem . 3, Audio quality on receive with external speaker or headphones is the best I have heard yet on an amateur transceiver. The noise floor on receive is also one of the best I have encountered. Audio amp is also quite, it’s a good trick to remove the aerials and turn up the volume as a rough guide on ten meters. 4, TX audio quality good, on par with pro2 or 746p and for the audio files out there check out some of the other postings on this site. 5, The external build quality is very good, all controls have a solid feel and are well spaced out, the display is large and clear, I need a clear display as my vision is no longer what it once was .VFO knob solid nicely waited 6, The receiver is not quite as good as my IC-781 but would hold its own with the IC-756pro2 and IC-746p,the later two radios have more bells and whistles, but their receivers or audio amps are not much of an improvement if any. Now this is a subjective comparison as I hear them. 7, The internal fans are very quite, much more so than 756p2 or 746p for comparison. I do not use the internal ATU very often if at all, but when pressed into service it’s fairly fast to tune. Kenwood TS-870 tuner would have the edge. 8, The PA is clamed to deliver 200 watts SSB, mine does closer to 240 watts, not that this is a problem the extra 3db is nice to have on tap. Mine rarely passes 30 watts as I generally fire up the amp. 9, This radio may not be the first choice for a top line contester, but it would suffice as a back up. I use mine for rag chewing to local hams and working the odd bit of DX. The radio is some three years and four months old and has just been serviced and realigned Mod number 01900 plus. All in all much is subjective when reviewing a transceiver this way. I like to put both radios on the bench and listen to them for a few weeks using the same filter settings and aerials with external speakers and head phones. Most of my listening was done with DSP switched off Bang for the buck or pound in my case, definitely a contender for DX or rag chewing. Marks out of ten, eight or four and a half stars bare in mind nothing is ever going to be a perfect ten 73 the ferret ‹^›‹(•¿•)›‹^›

Should have bought this rig years ago..
Time owned: 0 to 3 months
After 2-1/2 years I sold my Icom IC-756ProII and bought the IC-775DSP with one of the highest European serial numbers. In the meantime I did install all the Icom IF-filters, the TCXO and the 19' Rack Handles (great look!). My other rigs are: - FT-1000D - FT-1000MP Mark-V Field - IC-7400 (IC-746Pro) All four rigs are very good and have their own 'pros' and 'cons'. After a lot of comparisons I like the IC-775DSP the best. The IC-775DSP has the same excellent receiver as the FT-1000D (both with four IF's) and has some additional features like the DSP and the perfect LCD-display with very large frequency readout. The IC-775DSP is an extremely solid rig, from the outside and from the inside. It's much better manufactured than the today's rigs who IMHO have a very plastic feeling. For example a big difference between these rigs is the VFO-A knob; the one on the IC-775DSP gives a much better and solid feeling than the VFO-knobs on the modern Icom rigs. I don't like 50 MHz very much, so I prefer the HF-only rigs. I use the IC-775DSP mainly for SSB and as general receiver. The microphone is the Icom SM-20 and the loudspeaker the Icom SP-20. Great combination! The most important part of a transceiver for my usage is the sound of the receiver. It must sound very analoge, clean and quiet without anoying hiss. All these features like IF-filters, multifunctional display, etcetera are very nice at the first look, but when the receiver sounds like a robot these features just faint away.. I should have bought this excellent IC-775DSP years ago!

simply wonderful modern rig
Time owned: 0 to 3 months
To be brief, a bargain radio to consider buying used. I have a SN>2200 which is preferred, a true factory DSP and not a 'retrofit' unit sent back to Icom like early plain 775s. I have compared this to my 781 and it holds its own. My unit is completely filtered up including both 250 cycle CW filters in the 9MC and 455 IFs. The DSP is great on heterodynes and somewhat effective on T and R frequency response shaping. I do NOT notice the opposite VFO 'feedthru' that one reviewer noted.. and I tried to reproduce that finding, couldn't do it even on a crowded 7mc CW band. This radio used and fully filtered up, runs about the same price as a used 781. Overall I would select my 781 as first with the 775DSP a close second based on several on-air comparisons. 73, de K5YY

Simply the BEST
Time owned: 0 to 3 months
From serious DX untill ragchewing, there´s no competitorfor this rig. At same band, mode and time I could compare the 775DSP, FT1000MP, TS950SDX and the PRO and he has the best RX and TX clear. Exactly what we need from a hamradio. Strong as a stone (compare the knobs with the poor PRO !), half amplifier (200W) ! If possible I´ll buy one more.

Still great!
Time owned: more than 12 months
I replaced the original Tx filter by the FL-103 to have a wider bandpass (2.8KHz instead of 2.4KHz)and I am very happy with all great audio reports. I also run the IC-756ProII and I really don't know whcich one I prefer. I like the spectrum scope but I connot live without the 'old' 775. 73

My 775DSP retirement rig has arrived
Time owned: 6 to 12 months
My first ICOM was the 730, followed by the 735, 751 then the 751-A, 761, 765, 746. I have the ICOM bug and wished they made one of those also. I can say without a doubt that my retirement rig has arrived. I use the 775 on all modes except FM. I mostly operate CW and the 775DSP does everything the brochure says. I installed the AM filter and voice synthesizer unit. I find the built in filters adequate. The NR feature really eliminates background noise. The Audio Peaking Filter allows you to copy weak CW signals. And the noise blanker does not distort reception. The only negative feature is the dual watch does not allow mixed modes or reception on a diffrent band. If I sell my xyl's car I would get a ICOM-7800. Who knows she may retire and we could again be a one car and one ICOM family. My first rig was a 6L6 xtal oscillator and regenerative receiver. I still have all my ICOM's except the 761, 735, and 751. Keep up the good work ICOM. All my microphone plugs fit my rigs. Catch me on 3.552 early mornigns and late evenings and 3846.5 at 9 EST.
