Icom IC-7300 SETUP for WSJT/FT8 Digital Modes (Easy and Simple)

Icom IC-7300 SETUP for WSJT/FT8 Digital Modes (Easy and Simple)

Got a Icom IC-7300 you want to use on digital? I will show you exactly how to setup your Icom IC-7300 for use with WSJT-X and other digital modes such as FT8. These are my settings on my radio that work perfectly for WSJT-X.

**See below details on CI-V control and Split**
The baudrate you use in WSJT-X is dependant on if CI-V USB Port is set to Unlink from [Remote] or Link to [Remote].

Link to [Remote] = Use the CI-V Baud Rate on Page 1 of the CI-V menu
Unlink from [Remote = Use the CI-V USB Baud Rate on Page 2 of the CI-V Menu

**When setting Split in WSJT-X**
"Either method (Rig or Fake it) will result in a cleaner transmitted signal, by keeping the Tx audio always in the range 1500 to 2000 Hz so that audio harmonics cannot pass through the Tx sideband filter"

How close can Antennas be? (#449)

Bpb, KC1MOF, is setting up his second antenna, a mfj 1846 hex beam, and wants to know if his hustler 4btv may be too close, and if the two antennas may interfere with each other.

Antenna Showdown – New Packable Yagi vs Vertical in the 6m Sprint

Antenna Showdown -  New Packable Yagi vs Vertical in the 6m Sprint

Every year, the Central States VHF Society hosts a series of Sprint Sprint contests – one of which is a 50 MHz event. It’s a 4 hour contest with a point for each contact, and a multiplier of the number of 4-character grids worked. So I figured, I should probably operate from a SOTA summit for this event.

Spring Sprint Website: https://sites.google.com/site/springvhfupsprints/home/2021-information

Show Chapters:
0:00 Headed up the peak
1:42 Antenna intro
4:00 Telescopic Pole and Extended Double Zepp setup
6:19 Yagi Assembly and Setup
15:05 Contest Begins
21:32 Wrap-up

Not fully satisfied with the size of my 3-element 6m yagi, I constructed a larger one… much larger, actually. It consists of a 4-section 5 meter folding aluminum C-channel boom, and arrow shaft elements. Spread out on the boom are 5 elements which give a theoretical free-space gain of about 8.5 dBd. At 12 ft above ground, with sloping terrain all around on a summit, I expected pretty solid performance. And that’s what I got.

For the contest, I set up two antennas: the yagi, and an extended double zepp – a high-performing wire omnidirectional vertical antenna. I had each connected to an Icom IC-7300 with a coax switch to quickly change antennas. It was awesome switching back and forth to compare signal strengths on each antenna from the same source. The yagi crushed the vertical for longer-range contacts, but closer stations were much more mixed, likely due to signal polarization.
