Icom 7300 First Impression

K0PIR

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

I have had my 7300 since last Thursday. Its a wonderful little SDR radio, my first. The scope was one of the main reasons why I bought the radio. I was a bit disappointed by the fan noise at first but now I don’t really notice it. I use my Palstar AT-500 tuner instead of the internal tuner. Haven’t tried it yet maybe when I have the time to test it. Otherwise it’s a great radio. This my third HF radio in the 28 years I’ve been licensed.

Hi Rich,

Thank you for the write up on the 7300. I’m going to be purchasing one and probably using a Tarheel vertical antenna or G5RV. Did you disable to the AUTO tuner on the menu setting when using the external LDG? Do you have to do that? Also, do you have an interface cable with your LDG to the 7300 or do you just run from the antenna out of the 7300 to the tuner and tuner to antenna?

Thank you and 73s,
Vincent

Hi Rich,
I just purchased an IC-7300 and it’s hard to beat. I also have a TS-590 not the latest version which is very capable as well. I just wanted to mention on the subject of antenna tuning. Whenever feeding any antenna with coax where you’re trying to use it on a non-resonant band/frequency, the loss in the coax is substantial. If you were to change to ladder line on that same antenna and use a balun near the radio with a very short piece of coax to the radio, you would be much better off IMO. The variations you may find with the different auto tuners in situations like yours are usually based on the length of feedline. So if you were to experiment by just adding 10 or 20 feet of cable to your existing setup (perhaps with an SO-239 barrel), you would likely find the internal tuner would also tune your antenna.
Enjoy, and thanks for the first impression.
