I spent some time playing with the new IC-7300 transceiver this weekend on various modes. My first comment is that having used an IC-7100 for some time I was instantly familiar with about 90% of the IC-7300 controls. Most of the buttons are labeled the same and many of the setting menus are also the same. First thing I installed was a headset adapter so I can use the Koss SB-45 headset. I needed a plug adapter (which I luckily had on hand) to plug in my Vibroplex paddles. Rig control via Ham Radio Deluxe was fairly straightforward as the USB drivers are the same as the IC-7100. I started operating on 20m during the North America QSO party on Saturday with the 1/4 wave verticals.
My first impressions are that the rig works well (and possibly better) than the IC-7100 on SSB. My signal reports were solid 59’s and occasionally 59+ all across the USA. Also made some DX with favorable reports. Receive options make it easy to adjust RF gain controls and filters to help clean up the signals. I like the overload indicator which tells me to back off on the preamp or RF gain or both. The main learning curve for me thus far is in using the scope screen. Once you play with this awhile you get used to operating more visually. You can see whats going on across the whole band and find signals to tune into or find dead spots where the frequency is open. It is also easy to switch in the audio monitor to hear what you are transmitting.
Also tested digital modes JT-65, FT-8 and PSK31 after configuring the software for the rig. The audio scope helps look at the signal quality on digital modes. I did not find any notable differences in using the 7300 vs the 7100 on digital.
So overall I am impressed by the new rig especially on SSB Phone. I’ll likely expand on this review as I get some more time on the rig but I am happy with what I have seen thus far.
The IC-7100 is now setup as my base VHF/UHF rig and I hope to play with DSTAR on it for the first time sooner rather than later. I will continue to have it connected to my PC for rig control and can switch in HF when needed.

It took long enough but I finally setup the IC-7100 for VHF/UHF use. The rig was programmed with the local repeater frequencies using RT-Systems programming software and a download from Repeater Book. Pretty straightforward overall. I should be able to use the IC-7100 on digital VHF nets run hear locally. There is a 6:30 net on Wednesdays through the repeater and a Simplex net on Thursdays at 7pm. I will still share the discone between this rig and the Yaesu FT-2900R.
One thing I noticed thus far is that he IC-7100 is hitting the repeaters in Harlingen and in South Padre Island. Not sure why this is but glad it seems to work.
Next up I’ll try and configure DStar.

I broke down this week and bought an ICOM 7100 rig this week. I have it installed with an A/B switch to the Yaesu FT-450D so that I can use both (though not at the same time). As usual, any changes to my shack wiring has caused issues with RFI. I have resolved most of these except I am noticing my HRD logbook locks up occasionally. This is a sweet rig. I have tested it on SSB on the HF bands and got the internal sound card modes working with PSK31 and JT65/JT9. It has some neat DSP features on Phone that really work. The automatic Notch filter seems to work on most birdies and the noise reduction works quite well. Still learning many of the features and doing some A vs B comparisons with the Yaesu. It has DSTAR built in so I will be trying to play with the local DSTAR repeater. Also looking forward to try and do some satellite work with it as well.
I asked Cliff, KF5INZ, for one of his Easy Digi interfaces for my FT-2900R so that I can work the weekly digital VHF net. Cliff makes these interfaces in Los Fresnos and ships them globally. I picked it up from him at the CHARRO meeting last Saturday and will likely start getting it setup in time for Wednesdays net. The 7100 has this capability built in but I will likely be using the Yaesu for for this purpose.
