November 21st meeting

Our November meeting is coming quick. We will be talking about antennas and the basics. Please feel free to bring your antenna wows & questions. Herman & Don our club advisor will show different types of antennas with an explanation of what, where, & why.

Again, this will be interactive meeting from a rubber duck to a many element beam discussion forum.

Don’t be a dummy load and miss the gain of knowledge.

Pennfest review

Pennfest did not go quite as we originally planned. Some of it was was preventable and some was a learning experience. First we owe a big thank you to Bob (W0BAD) who was able to be there for the club. Jeff (KG7ONF) and Bob were there for set up however, it didn’t take long for us to realize that we didn’t have anything to advertise the club so we spent our time under the Richfield CERT canopy tent. What we weren’t expecting was the CERT team brought out a generator which made it extremely difficult to engage with the public and have them hear people talk on the radios.

I do appreciate Matt (N0TNL), Tom (KE0KTD), and Don(KC0TJ) for being able to monitor the repeater for whatever conversations we were able to have. If anybody else hopped on the repeater and I didn’t mention because I didn’t hear them, I apologize.

In the end, for next year we have a lot of room for improvement. The biggest improvement that I ask for is trying to get more participation. Without the members of our club getting involved, we can’t get more community involvement. I hope to see people at the meeting on Wednesday and the Get On The Air event next Saturday, September 22nd.

 

A sad day

Sept. 11th, 2018

It’s Time to Retire.

It’s been a wonderful 36 years for us at Radio City and we have decided to retire and close Radio City. We are so thankful for the many years of support and we have enjoyed working you, our customers. The technical, intelligent and polite conversations plus advice have been invigorating, thus making this decision extremely difficult for us.

We appreciate all the teachers, Elmers, VE examiners, ham and astronomy clubs efforts in growing new ham radio operators and amateur astronomers into our special community.

We will also miss going to and supporting amateur radio and astronomy clubs all over MN and IA at their events. We will greatly miss all the friendships we have been privileged to maintain with many of our customers.

We plan to exit by this year’s end or a bit sooner as we empty our shelves of new and used materials.

Upcoming Events:

Sidewalk Sale:

Our final sidewalk sale is this Saturday Sept 15th. We are digging deep for this event. It will be held rain or shine. Currently forecasts are calling for a mild 85F with just a 20% chance of showers.

Final Goodbye Tour:

We will be at Smartfest in Cologne, MN on Saturday September 22nd. We will also be in Carlton MN for their Fallfest on Saturday September 29th.

Goodbye Party:

Please come on by on Saturday October 6thfor our good bye party. We will of course have cake and coffee for everybody.

Other Necessary Details:

Service:

We will complete servicing items we currently have in the service dept. We will not be accepting any additional ‘Out of warranty’ items. ‘In warranty’ items will be still be processed by Radio City per normal until about October 31st, 2018.

Consignment :

We will no longer accept more items for consignment. All items that have NOT been sold need to be picked up the week of Oct 13th, 2018. We will consider all items not picked up by then to be abandoned.

In closing we will very much miss all of you and perhaps there is someone out there interested in running the store under New Management.

Thanks again for all your support,

Dan and Maline Fish

 

Pennfest

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

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.

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

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

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.

Some Contest fun after FD

After Field Day fun!

I, KCoTJ had fun working many contests that was around the forth and all was easy to do. The one I really liked was 13 Colonies and can’t believe it has been going for 10 Years. I did the contest right after my dad passed away. It was my way to learn how to do HF without my Dad’s help and I was better than I thought back then. I worked every station easily I aimed the antenna and tuned up the stations. I was learning that even with a pile-up I was the strong one. I found my dad had a great tuned antennas and made me a quick study. http://www.13colonies.net   However this year I mixed it up a little. I decided that all my cantacts would be 5watts I was very good at that, but the bonus was Great Britain and he was doing a lot of non-phone or voice calls. So I struggled and tried to hear him there no success. He finally near the end went back on voice and I could hear him. I had a phone app that WEBSDR I scanned one that I could hear him and it work fine, but I was noticing that there was no delays from the stations I could hear on both. So my great idea was to see if I could hear myself nope, but he was able to hear me with a 59 report. I RXed him on my cell 57 to 59 and conform my info. Yep-pi a clean sweep, I no longer was qrp but I made all my Qs. So in my haste I found that he was on D-Star earlier, I sent a DXcluster that I was on D-Star REF063B which he was on 10 mins prior. Next thing there he was. I set my radio to 5watts and QRP status was back. Below is a clip of the next station working him. remember this contest is always during the week of 4th of July for 1 weeks time.

 

I wanted to give a shout out all that make this a fun contest….
