First Four States Fusion Net - Awesome !!

The first run of the Four States Fusion Net was a complete success and just in time before the winter thunderstorm heated up. We had 10 total stations on the net, 2 states represented. There were 6 different Fusion models used to talk on the FSFN this time.

Most radios had their GPS turned on and we got good information from that and the mileage matched on both sides that were reported. The longest was WØHL Dennis who was 36.6 miles away in Nevada and he had a nice clean signal. The Closest to me was .6 miles N3LRH Leon and Matt KØVLL was mobile and started 1.8 miles and he reported when he stopped he was .4 miles from me. We did have KBØDXS from Racine MO but I don't think I received his GPS info.

I will track this information when possible and report it here. Let's keep it rolling and be sure and to invite those operators you know using Fusion to join us. It will be awesome when we get our first actual all FOUR STATE check ins!

Here is a rundown of the checkins, radios and distance

(NC) KAØEGE Jeff FT1D
WDØCFH Jack FT70d
KØVLL Matt FTM-100 1.8 to .4 miles
KEØCZR Milton FTM-100 25 miles SSE
KØSMK Willis FTM-100 19.8 miles S
N3LRH Leon FTM-100 .6 miles N
NØSLT Steve FT70d
WØHL Dennis FTM-400 36.6 miles NNE
KBØPQP Tyler FT-991
KBØDXS Brain FT-3200

Four States Fusion Net

We are having a Four States Fusion Net every Wednesday at 8pm on the 442.675 repeater or in the KANSAS CITY WIDE network. Everyone with a Fusion radio is invited to participate when possible. We would like to get 3-4 volunteers to run net control once a month so let us know if you would like to help out!

A lot of us have a Yaesu radio that does Fusion and we just are not using it. Let's test and get more familiar with the C4FM side of our gear. We will use DN mode and it is recommended to NOT have your radio in "AMS" mode or Automatic Mode Select as you could have your radio change to FM during the net and could be confusing.

Here is a link to the Net Control Script !!

And here is the link to the LIVE ONLINE LOG !!

SEKARC Exam Day Friday

We are starting a regular new feature here on SEKARC every Friday. This could help everyone refresh their memory and to keep learning new things. We will post 2 questions each week from the GENERAL Class Exam and the answers will be posted with next Friday's posted questions.


Let's have fun and keep learning and even discuss these questions at the Coffee QSO. I am tracking the posted questions so there SHOULD not be any dups. Have fun!

 
G1A05 (A) [97.301(d)] Which of the following frequencies is in the General class portion of the 40-meter band in ITU Region 2?
A. 7.250 MHz
B. 7.500 MHz
C. 40.200 MHz
D. 40.500 MHz

G3B03 (A) Which of the following applies when selecting a frequency for lowest attenuation when transmitting on HF?
A. Select a frequency just below the MUF
B. Select a frequency just above the LUF
C. Select a frequency just below the critical frequency
D. Select a frequency just above the critical frequency

Winter Field Day 2019

Greg WI4T

Winter Field Day 2019 was a TREMENDOUS success. There are some details listed below along with photos and video from the event. A special thanks to Tyler KBØPQP for hosting the WFD event this year. The antennas were great, indoor shack was warm and we had lot's of operators and visitors. Greg even gave us some bonus points by making a satellite contact with WA6RLR in California on SAT AO91 (see video below). What a great field day!

Thank you for these members and guests operating, logging, helping with antenna setup and shack wiring and for stopping by!! Great job by these hams, Tyler KBØPQP, Matt KØVLL, Jeff KAØEGE, Willis KØSMK, Ron WØSEJ, Ron KBØNRG, Phil KØPR, Milton KEØCZR, Leon N3LRH, Steve NØSLT, Greg WI4T, Cecil NØEHP and Bob AEØAQ visiting from Parsons. If I missed anyone please let me know!

Tyler KBØPQP Presentation in Parsons

SEKARC member Tyler Costantini KBØPQP will be giving his EMP and Ham Radio presentation at the Parsons Ham Club meeting on Monday February 4th, 7pm at the Arboretum, S 21st St & Briggs Ave., Parsons, KS 67357. See clickable map below for directions.

This will be similar to the info he presented to the SEKARC a while back. If you can, plan to attend. The Parsons club is working on reviving their club and it would be great to show support from the SEKARC.
