Pennfest

By Uncategorized

Just a reminder to everyone that this Sunday is Pennfest in Richfield. It runs from 12 to 5 p.m. Once it starts, Penn Ave. will be closed off so if you are able to help with setup than be there early to park, help set up, and than find a close parking spot off of the street. We are going to be partnering with the Richfield CERT group. Our club will be located near the Richfield water tower. Once again anyone who is able to make it to show to the public a little bit of what our club can do and what amateur radio is about would be appreciated. If you cannot make it than please monitor the 444.475 repeater so we can demonstrate to the public how ham radio works.

August meeting minutes

By Uncategorized

Thank you to the members who showed up for the August meeting.

The main focus of our meeting was to prepare for Pennfest and our GOTA event in September. For Pennfest we are teaming up with Richfield CERT and will demonstrate what ham radio is. Pennfest is September 16th from 12-5.

Our GOTA event will be the following Saturday, September 22nd from 11-3 at the Richfield community center.

Finally the Twin cities FM club is having their last chance swap meet a at the West Medicine Lake Community Center.

please be sure to check in on our Thursday night next and the next meeting will be September 19 at the Richfield community center at 7 p.m. It is after Pennfest but the Wednesday before the GOTA event. I hope to see as many people come and participate as possible.

Sam (future ham radio operator)

Meeting minutes -Field Day was a great success. Thanks to Bill the Fox hunt was a great time. 63 people showed up and we made 187 contacts, 60 of which were from Herman. Lewis had many compliments for his cooking. People were talking about the food after field day and are looking forward to next year. Our club model for field day is a great example that other clubs are interested in following to get the hobby to grow in the community.

we are planning on having a setup for Penn fest in Richfield on September 16th and we are planning a Get On The Air (GOTA) event the Saturday after on September 22nd. It will be from 12-4 p.m. and we are looking to have it at the community center.

Don gave us a demonstration on the HT’s of the second and third harmonics of a Radio signal which was pretty interesting to learn about.

we are still having a problem with interference on our repeater. Keep monitoring the repeater and report it if there is any interference.

Finally the club is trying to get the study group going again. more details to come but let us know if you want to join us.

I look forward to seeing everyone at the next meeting and hearing you on Thursday during the club net. Our next meeting is on August 15th at the Richfield community center at 7pm.

Basic operations

By Fun, Uncategorized

Basic Ham Radio Operations…

Simplex…

      Communications method to talk directly to another station with no additional aides. 

 

Equipment need:

Is each person needs a transmitter & receiver on the same frequency.

 

(KA∅AAA) TX & RX <————-> 146.520

(KB∅BBB) TX & RX <————-> 146.520

 

Advantages: more private, more local, can be used anywhere, & simple programming

Disadvantages: needs high power, not used a lot, & limited range

 

 

Half Duplex… 

     A common repeater system. This has one common TX frequency & one common RX frequency. 

 

Equipment needed:

Everyone transmits on one frequency & everyone receives on second frequency with another source to receive everyone’s transmitted signals on one frequency and send it back out to another set frequency. 

 

(KA∅AAA) TX ———–> 449.475 (Repeater input)

(KA∅AAA) RX <———- 444.475 (Repeater output)

(KB∅BBB) TX ———–> 449.475 (Repeater input)

(KB∅BBB) RX <——— 444.475 (Repeater output)

 

Advantages: If you able to hit the repeater you can use all the repeaters resources allowing an extended ranges to a weak signals or unheard directly, have more likely to have another person on, & less power needed to talk.

Disadvantages: Repeater must be in a good location, can be busy, doesn’t work everywhere, & may have restricted access.

 

 

Full Duplex… 

     This is most common with telephone calls. You can talk & listen and the other person talk & listen at the same time.

 

Equipment needed:

A low powered transmitter on one band and a receiver another band. with everything reversed on the second station.

 

(KA∅AAA) TX ——–> 147.555

(KA∅AAA) RX <——– 446.000

(KB∅BBB) TX ——–> 446.000

(KB∅BBB) RX <——– 147.555 

 

 Advantages: Have real time updates, may be more exclusive, you can throw off the other persons concentration, send multiple information simultaneously, & kind of fun.

Disadvantages: each person needs 2 radios on 2 different bands, your location needs to be close to the other station, you can get possible feedback, This is harder on the radios & takes a bit of skill.

 

 

Hope this helps everyone. If you want a topic to have posted please email us at: W0RRC.RARC@Gmail.com

Field day and upcoming meeting

By Uncategorized

Thanks to everyone who was able to make it to the June meeting. We went over the final details for Field Day. Field Day was once again a big success. Ben from Radio city came by and took photos of our site and you can them at www.radioinc.com as well as other Field Day sites that he visited that day. Our next meeting is July 18 at 7 p.m. at the Richfield community center. I hope to see everyone there.

ISS RXed by KC0TJ early Sunday!

I was scanning on a big VHF band opening early Sunday and I jumped out of my half a sleep slumber when some strange tones came from my radio.  I realized this was SSTV signal (Wow!) I haven’t heard that on radio for a long time. I went to check the freq and it was 145.800? I had thought it might be from out of space? I also went to turn on my other radio to see if I could decode this message. When I was more alert I quickly turned on my MMSSTV program and the sound was set to the wrong radio. (Crap!) I changed that when I was getting nothing on my PC and half the picture was already done. (Crap!) I saw mode was pd140 and then picture stopped. I had no cw ID or other encrypted info. (Crap!) I then try screen copied the partial image in hopes to figure out what I had. Then it started again and I was ready for it all. I had to keep adjusting my squelch to RX.  I went to my cell phone app to find the ISS and it was already starting over Lake Superior. I also tried to Googled what frequencies they used and mode and everything was checked to what I had everything set to. I realized afterwards that I left my antenna aimed North East and it was an extra bonus to get the whole picture see below. This was also one of the ones used by them per the website link below, and I did log it on that website.
