W0JV Repeater Testing

The CTCSS tone for the repeater is 192.8; your radio must generate and insert this tone in yout transmitted signal in order to open the repeater.
If this CTCSS tone is not present the repeater ignores your signal.

One of the repeaters in Minnesota uses the same frequencies as our repeater and this time of year is is not uncommon to hear from them.
We are investigating measures to allow you to ignore the traffic from the Minnesota repeaters.

Normally the repeater controller suppresses this CTCSS tone as it is (annoyingly) audible.
You would hear the CTCSS tone as a low pitched hum.
Some find it annoying so we typically leave it suppressed (the repeater controller filters it out).

We are conducting a test by leaving the transmitted CTCSS tone on for the next few days.
If you can hear it and find it annoying, please give us your opinion during the Sunday Evening Net.
The purpose of the CTCSS tone on output is to allow you to ignore traffic from the repeater in Minnesota this time of year.
We think the repeater controller can manage split CTCSS tones, where the 192.8 tone is required to open the repeater, but the repeater controller sends out a different (lower) tone.
This requires a bit more setup on your radio, but the hope is that you won't hear it (this assumes your radios audio bandpass filter has enough out-of-band rejection)

More discussion of this test will be heard on the Sunday Evening Net.

What is Amateur (Ham) Radio?

This section was suggested by Brownie Girl Scout leader Carla Rodriguez and her daughter Willow. Her Troop has been talking about ham radio in their meetings lately while learning about emergency preparedness and communication skills. One of the girls mentioned that her grandfather and father have been ham radio operators for many years, and all the girls are really interested! We hope you will be, too!

Willow found a great introductory web page, and I am pleased to publish a link to it here:

This web page concludes with a list of many interesting links to other web sites about amateur radio. The first one, which I will repeat here, is this page, published by the American Radio Relay League (ARRL):

My thanks to Carla and Willow for providing the inspiration for this section!

Weather Spotter Safety

Skywarn ®  
NWS is now conducting the spotter training via webinar on Tuesday and Thursday

We have provided a page of Weather Spotter Safety information (from the National Weather Service) to remind you of proper safety procedures when you are engaged in spotting severe weather for the Johnson County Skywarn® Net. Please read this information before you become active in Weather Spotting, and review it every month or two during the severe weather season!

Please Keep Your 2 Meter Radio ON!

2m Radio
To truly make amateur radio a valuable emergency communications tool here in eastern Iowa, and to make our local amateur community more welcoming and open, we must all resolve to keep our 2 meter radios ON, both at home and in our automobiles, at all times (except maybe when asleep!). You should try to monitor at the very least the 146.85 (WØJV) repeater. If you have scanning capabilities on your radio(s), it would be helpful to include the 147.15 Coralville repeater and the national simplex frequency (146.52 MHz) as well. And, if you are so truly lucky as to have a dual-band FM radio, there is some activity on the 444.75 MHz repeater, too.

Let's all give it a try! Keep the radio on, and respond when somebody announces "KØXYZ monitoring". Most importantly, respond to visitors to our community who are looking for directions or just somebody to talk to as they pass through town. We can have a much more enjoyable, open and friendly hobby if we all will simply have QSOs with other local hams or travelers as they pass by on the Interstate. It doesn't have to be a half-hour "rag chew" -- short "How are you today?", or "Can you believe this weather?" QSOs are often quite adequate.

So, how about it? We'd love to hear you on 2 meters!

Share a Radio Program

If you have never been on HF and would like to find out what all the excitement is about, the Share a Radio program provides a way for you to become acquainted! Share a Radio allows hams who have little or no HF experience or who do not currently have an HF station to team up with hams who do have HF stations for a demonstration or to get some time on the air. When visiting a station, you may use your own call sign and log while operating under your own license class privileges; or with the station owner as control operator, you may enjoy the "Extra Class" experience. Please visit our Share a Radio page for more information!

DX Code of Conduct

Click to visit DX Code of Conduct
(The following is from the DX-Code web site. This should be required reading for everyone who chases DX. Please read and heed these rules -- or, even better, a copy of the Code in PDF format is available here for you to print out and hang over your operating desk! Just think how much more pleasant DXing would be if only everyone followed these rules!)

It is no secret that the on-the-air behavior of hams, especially in pileups, has gotten worse in the last few years. Unpleasant, uncivil, impolite behavior of our fellow hams reduces the enjoyment of our hobby.

It does not have to be that way nor should it be. Impolite behavior is counter-productive and simply inconsistent with the aim of our hobby, to have fun.

Just as we work to improve our technical skills, we should all aspire to hold ourselves to the highest ethical operating standards. This Code is a reminder of the high ideals of which we are all capable.

  • I will listen, and listen, and then listen some more.
  • I will only call if I can copy the DX station properly.
  • I will not trust the cluster and will be sure of the DX station's call sign before calling.
  • I will not interfere with the DX station or anyone calling him and will never tune up on the DX frequency or in the QSX slot.
  • I will wait for the DX station to end a contact before calling him.
  • I will always send my full call sign.
  • I will call and then listen for a reasonable interval. I will not call continuously.
  • I will not transmit when the DX operator calls another call sign, not mine.
  • I will not transmit when the DX operator queries a call sign not like mine.
  • I will not transmit when the DX station calls geographic areas other than mine.
  • When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
  • I will be thankful if and when I do make a contact.
  • I will respect my fellow hams and conduct myself so as to earn their respect.
For a detailed discussion of the Code, please visit DX-Code.org.

What's New?

News of the day.

3Y0J Dxpedition to Bouvet Island, January/February 2023

Press Release from the Intrepid-DX Group
As we completed our successful VP8STI-South Sandwich and VP8SGI-South Georgia DXpeditions in 2016, we began to plan for our next Dxpedition. Our target is the Norwegian Island Bouvet. This is the #2 most wanted DXCC entity.
At this time, it gives us great pleasure to announce that we have joined forces with Intrepid Norwegian DXpeditioner Ken Opskar-LA7GIA in our quest to activate Bouvet.
Together, in January 2023, 14 men will board the Braveheart in Capetown and make the treacherous voyage to Bouvet. We will plan to spend twenty days at Bouvet and weather permitting, we plan to have 14 to 16 good days of radio activity.
This will be an arduous and expensive mission. Our budget is $764,000 USD and the 3Y0J team will fund much of this mission. We desperately need the global DX Community to support our mission and help us make this important activation of the #2 most wanted DXCC entity. It is only through this kind of support that we can achieve our mission of making 100,000 contacts or more from Bouvet.
We plan to make best use of Propagation and Modes on 10-160 meters.
We pledge to assemble the strongest team possible and to use good operating practices to optimize your ability to reach our stations. We are confident that the Braveheart crew can get us there and back safely.
In closing, we especially wish to recognize and thank the Northern California DX Foundation and the International DX Association as our premier donors. Without the support of the NCDXF and INDEXA, operations to the world's rarest entities would not be possible.
You can follow our plans from our website and the 3Y0J Facebook pages:

INDEXA is a proud supporter of the 3Y0J DXpedition to Bouvet!

Video Conference Initial Testing

We are rolling out (or at least giving it a try) a video conferencing system for the monthly meeing.
This, we hope, will allow us to present an interesting program, much as we would at our (seemingly ancient) face-to-face meetings.

We plan to use the Sunday evening net to stress test the system prior to having it in active use for the August Meeting.

Links to the video conference may be found near the top on the primary ICARC web page.
Clicking on the Sunday Evening Net Link will take you to the Local & HF Nets page where the actual link to the video conference meeting.
Please let us know how it works for you.
