January Tech Night Making the Most of Your HF transceiver

The January Tech night was about getting the most out of your HF transceiver. Fred had an interesting  PowerPoint presentation where he demonstrated how to do just that. For anyone else new to HF, I wanted to comment on it here. In his presentation, he described how you should use filtering first and digital signal processing (DSP) as a last resort. That’s the exact mistake I was doing. if you use a lot  DSP with a narrow filter selected the audio sounds hollow and really difficult to listen to. If you turn off the DSP  select the narrow filter and then bring up the DSP if needed you get less noise and a pleasing audio output. Also turning down the AF gain can be your friend too!

Home Brew Your Own Arduino UNO

The first question you may ask is, Why would I want to build my own Arduino UNO?  Economically speaking it does not add up in your favor after you acquire the parts and consider the time it takes to put it all together.  This is especially true when you consider that a Nano “clone” could be purchased for around $3!  You might have a permanent use application that makes building one your best option?  Maybe you just like to learn and do stuff just because you can!

The unit below is built on a prototype shield that has become the main board.  For my keyer application, I have no need of USB communications and I can keep the wiring down to only what is needed.  The 5v regulator will soon have a small heatsink as it gets warmer than I would like.

Below is the other side of this board.  I used #4-40 screws as “legs”.

Our Club Moving Forward Into 2017

Our club has accomplished a great deal in the last year. We have grown to over 130 members. We have introduced many new people to Amateur Radio, helped them to earn their Licenses and worked with them to get on the air and develop their knowledge and operating skills. We’ve also worked hard to provide opportunities to enjoy and learn about Amateur Radio for members of our club and for the Amateur Radio community which we are a part of.

Much of the credit for our club’s success this past year belongs to you, our members. We very much appreciate all that you have done to contribute to our success and the fun that we have all had as part of what we have done together. Your enthusiasm and support provide great encouragement and inspiration to the many new members who have joined us as well as to all of us who are part of our club’s Leadership Team.

We, as your club’s Executive Committee, have been working on a set of goals and plans to continue on this path during 2017 – to provide even better opportunities for our members to learn more about and to enjoy Amateur Radio, to continue to encourage people to join the Amateur Radio Service, and to provide opportunities for STEM learning for young people.

Our goals and focus for 2017 centers around continued success in and focus on the following areas to benefit both our members and our community as a whole:

To do these things and to be successful as a growing club, we are also pursuing status as a 501(c)(3) non-profit. This will enable our club to more effectively secure support from other groups to further our work towards these goals.

Each of us has taken ownership for creating a focus on meeting different aspects of our goals for this year. We are planning to share more about our plans for 2017 at our February Club Meeting.

We are asking that each of you, as members, to consider how you can get the most from all of these and the other opportunities that our club provides. We are working hard to try to create something for everyone that can provide enjoyable opportunities to have fun, to contribute, and to expand the value that we all create and derive by being part of the Amateur Radio Service. We are also asking each of you, our members, to consider helping us with these initiatives in 2017.
