Working the CQ WW SSB Contest on the ICOM 7300

I was on a short business trip to China last week and arrived back home late Friday night after the CQ WW SSB contest had already begun. I started working the contest after lunch on Saturday using the Icom 7300 on 100W and with the N1MM logging program. I took a little time before starting to enable the spectrum display feature on the logging software as well as the spotting capability. This was fairly straightforward and only required that I change the baud rate on the rig. How did this all work? Well all I can say is I wished I had this in earlier contests! Here is a view of my contest screen:

Spots match up with the spectrum display and a simple click on the signal of interest adjusts the rig. There are screens that display the spots that will maximize my score which is really handy. I operated search and pounce on 10m, 15m, 20m and 40m bands. Here is a summary of my score:

2017-10-30

Action on the daytime bands was centered on 15m. There was some intermittent activity on 10m during daytime hours. 20m was very active but also seemed difficult for me to make contacts. Not sure if this was related to the antenna or propagation conditions. 40m at night was also quite active with very decent DX. Overall a good cross section of DX with 63 DX entities contacted over 35 CQ zones.

Lots of fun with this and a good test of the vertical antenna system.

Bad Behavior on HF Pileup

It’s been awhile since I have seen real big DX pileup. That was the case yesterday afternoon with Annobon Island on 20m SSB. I was not able to make a QSO. The operator was working split and listening up 5 to 20. Most of the stations responding were stateside and while many were well behaved the number of lids and cops on the frequency made it extremely difficult for all operators. I am a strong believer in the DX code of conduct.

The IC-7300 waterfall makes it fairly easy to see where the DX station is listening. When he calls QRZ the waterfall becomes almost solid in a band between 5 to 20 kHz. It dies out when he answers and then the answering station comes out in the spot he was listening. Some monitoring of this will tell you where he is listening to maximize your chances of him hearing the call I hope to see this op again this afternoon as he is only QRV for a few more days.

IC-7300 setting to work with WSJT-X (and others)

I prepared a short how-to on setting up and ICOM-7300 with WSJT-X for working digital modes. If you can get this working, other digital software can be easily configured in a similar fashion. The file can be found on the “Projects” page or from this link:

ICOM 7300 – First Impressions

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.

Ham Shack Changes – Part I

I made some changes to the Shack today. First up was removing the FT-450D and the FT-2900R and their associated cabling. The FT-450D will become a portable station along with an MFJ-4230MVp Power Supply in a pelican style case. The FT-2900R will eventually make its way into my Ford F-150 for 2m mobile operation. The IC-7100 is now working as my VHF/UHF rig. I have kept the rig control and HF connection intact so I can also use it on HF. I have now installed a new Icom IC-7300 for my HF base rig. Installation was stratight forward and operation is VERY similar to the IC-7100. The main new features are of course the spectrum scope and the filtering. I have Ham Radio Deluxe, N1MM+, JTDX and WSJT-X configured and working with the new rig.

Today is the North America QSO Party so there is an active band on 20m to play with the new rig. I’ll review later as I have more operating time built up on the rig. Here is the new “minimalist shack”…so far:

Addtional changes in the works are:

  1. Swap my ground braided strap connections with copper strap.
  2. Install S9 Antenna and radial plate
  3. Secure the FT-450D and FT-2900R in their new homes

Major Changes to the Ham Shack are Planned…
