The Icom IC-7300 vs. WinRadio Excalibur: Which do you prefer?


[UPDATE: Read the full IC-7300 review–along with listener survey results–by clicking here.]

In the past, receiver shoot-outs in which I’ve provided sample audio for “blind” comparison––meaning, the listener does not know which audio sample is associated with which radio––have produced particularly positive feedback from Post readers.

The WinRadio Excalibur

So I’ve decided to do this for the new Icom IC-7300 transceiver. I’ve pitted the ‘7300 against a benchmark receiver: the WinRadio Excalibur.

I have a number of SDRs (software defined radios) in the shack at the moment, but I picked the Excalibur because it’s the closest in price ($900 US) to the IC-7300 ($1500) as compared to my Elad FDM-S2 ($520) or the TitanSDR Pro ($2500).

Recording notes and disclaimers

Both the WinRadio Excalibur and the Icom IC-7300 offer native digital audio recording (nice touch, Icom!). The Excalibur simply records the AF to a file on my PC’s hard drive, while the IC-7300 records the audio to an SD card which I can later transfer to my PC.


I’ve been using the Excalibur since 2012, so I’m very familiar with its recording feature. I was not, however, familiar with the IC-7300’s digital recorder, so prior to making recordings, I checked to make sure its recorded audio was a fair representation of its live audio. To my ear, the IC-7300 recorded audio was nearly identical to that of the live audio, so I used the 7300’s internal recorder rather than one of my external recorders.

Both receivers shared my large outdoor omni-directional horizontal delta loop antenna for each test.

To keep the comparison on as equal footing as possible, the receivers shared the same antenna through my Elad ASA15 antenna splitter amplifier. Though the ASA15 has both 12dB amplification and –15dB attenuation, I employed neither.

The ASA15 allowed me to make the following recordings simultaneously.

In each case, I tried to set up both radios using the same filter widths, gain, AGC settings, and (as much as possible), audio level. I didn’t engage a noise-reduction feature on either rig.

Note:  the only exception to the radios’ equal treatment was in the AM mode recordings, in which I used the WinRadio’s AM Sync (AMS) mode. Why? Frankly speaking, 99% of the time during which I use the Excalibur, I do employ its AMS mode as its AM mode often sounds “hot” and over-driven when band conditions are as noisy, as they were last night.

The IC-7300 does not have AM synchronous detection (AMS mode), but I felt it compared very favorably to the Excalibur in AMS mode.  The IC-7300 would have easily beat the Excalibur in this test had I only used the Excalibur’s AM mode. In the end, as a shortwave listener, the goal is to compare the total capabilities of broadcast performance between the two receivers (thus using sync mode if available, to maximize broadcast listening performance).

Please vote!

At the end of this post, I have an embedded a survey in which you can vote for the sample recordings you like best. Each recording is clearly labeled to denote that it’s either from “Radio A” or “Radio B” (I had my wife draw names from a hat to determine which radio would be labeled as A or B).

Since there are quite a few recordings, I’d suggest jotting down your notes separately before completing the survey.

Or, alternately, you can open the survey in a separate window by clicking here.

And now…here’s the recordings.

Ham Radio Band recordings

The following recordings were made on the 40 meter ham radio band yesterday evening. Both radios have the same filter width: 250 Hz in CW, 3 kHz in SSB.

Weak Signal CW (40 meter band)

Radio A

Radio B

Weak/Strong SSB QSO (40 meter band)

Radio A

Radio B

Shortwave Broadcast recordings

The following recordings were made on the 31 meter broadcast band yesterday evening. Both radios have the same filter width: 9 kHz and 8.2 kHz.

Weak Shortwave AM (Radio Bandeirantes 31 meter band)

Radio A

Radio B

Strong Shortwave AM (Radio Romania International, French 31 Meter Band)

Radio A 

Radio B

Mediumwave Broadcast recordings

Note that the following mediumwave recordings were made during the morning hours (grayline). The strong station is the closest AM broadcaster to my home; it’s not a blow-torch “Class A” type station, merely the closest local broadcaster.

In the “weak” sample, I tuned to 630 kHz, where multiple broadcasters could be heard on frequency––but one was dominant.

Both radios are set to a filter width of 9.0 kHz.

Strong Mediumwave AM (1010 kHz)

Radio A

Radio B

Weak Mediumwave AM (630 kHz)

Radio A

Radio B

We want to hear from you!

Use the form below to vote for the recordings you prefer in each section.

I’ll close voting at 12:00 UTC on Thursday April 21, 2016. Thank you in advance for your participation in this survey!

Look what just landed on my desk: the new Icom IC-7300 direct sampling transceiver


[UPDATE: Read the full IC-7300 review–along with listener survey results–by clicking here.]

I have a new toy in the shack: the Icom IC-7300.

Last night, a good friend handed over his brand-spanking-new IC-7300 and is allowing me to evaluate it over the next week or so.

The IC-7300 is Icom’s first “entry level” RF, Direct Sampling System HF transceiver.

I’ve only had the IC-7300 on the air for a few minutes, so can’t comment about performance. I can say that it has one of the most intuitive interfaces I’ve seen on a transceiver with so many functions. I also love the spectrum display–small, but large enough to see all of the pertinent information:


It’s a slick machine, indeed!

Time permitting, I plan to post a few audio clips and get reader reactions much like I did for in the portable shoot-out.

I’ll compare the IC-7300 to my Elecraft KX3 and a few SDRs as well. Of course, I’m evaluating this during one of the busiest times in my life, so we’ll see how quickly I progress–!

Simply follow this tag for updates: IC-7300.

Icom IC-7300: retail price and shipping dates set

Icom-IC-7300-FrontMany thanks to Dave Zantow (N9EWO) who notes that Universal Radio is accepting orders for the Icom IC-7300 at a price of $1499.95 US and expects to ship units by the latter part of this month (March 2016).

Several of you have asked if I anticipate reviewing the IC-7300–Icom doesn’t issue many loaners for review, but I will check with them nonetheless.

Icom introduces the IC-7300


Icom introduced a new general coverage transceiver this year at the Tokyo Hamfair: the Icom IC-7300.

Icom has released a preliminary spec sheet (click here to download), but no pricing information yet. The IC-7300 will most likely be the least expensive Icom transceiver with a full spectrum display.

At first glance, I like the form factor and touch screen display–the panel appears to be less cluttered than many other large-display models. The ‘7300 has dedicated knobs for passband tuning and AF/RF gain (major plus in my book). It also comes with a built-in automatic antenna tuner.

I’ll post more info once Icom releases pricing and availability.
