Peaked out of hibernation for a quick #hamradio #amateurradio CW #morsecode #qrp #pota #parksontheair activation with my #hb1b into #linkeddipole

@alex #introduction

Hi Alex and All:

Steve here. My NU7B call is in QRZ. This past fall my wife and I moved to the province of Pescara, Italy. I'm presently applying for my I*6*** callsign - not sure what the turnaround time will be for that. This is our new home.

I've been a ham since 1973. Made a career in RF IC design. Radio is main hobby - but also do solar photography, and side projects. Haven't set a new station up yet but that should be soon.

GA Everyone! Next week my YL and I will be in Chile. I plan on doing some POTA from Torres de Paine National Park (CL-0092), which has 0 POTA Activations, while we backpack there. Grid Squares FD93.

We'll finish up our trip in Santiago, Chile where I plan on activating Cerro San Cristobal (https://sotl.as/summits/CE3/SA-019)

Please add CE/N7KOM and CE3/N7KOM to your HamAlerts!

I'll have my KX2, so I plan on doing some high bands!

Israeli Prime Minister Netanyahu is said to be hoping diplomatic achievements anticipated from Monday’s planned talks with President Trump at Mar-a-Lago will score him political points and improve his image ahead of Knesset elections. https://www.jpost.com/israel-news/politics-and-diplomacy/article-881485

Connecticut recently rolled out “The Pizza State” license plates. I asked the DMV if they could combine it with the amateur radio license plate, and they did. This might be the state’s only combination pizza/amateur radio plate.

If anyone wants to make a QSO at the nearest Frank Pepe’s, you know where to find me.

last 24h - it's not perfect DX but hey, I'll take it, considering I'm using a very thin wire hanging off my study window towards the garden, with a non-existing grounding...

A half-wave dipole for 20 m also covers 30 and 40 m with a tuner. Use it for 60 or 80 m? Bad things start to happen.

Short dipoles are attractive for city dwellers like myself! But to feed them, high voltages AND fairly high currents are required. Losses become an issue.

I developed FLOSS Python code to run nec2 antenna simulations automatically. I showcased it studying relevant aspects of dipoles as they become shorter and shorter.

Good fun. I learned a thing or two.

Antenna simulation driver showcase

I provide a Python package antenna_simulation_driver. When you are here, I assume that you already knew that and have a notion what that is about. If you don’t, I recommend you head over to that proj

4 years later, my 3D printed ball bearing protectors are still in excellent shape. #hamr #amateurradio #3dprinting

Here is the detailed writeup:

Protector for SKF ball-bearings on antenna masts

At ED1R we use industrial ball bearings on our towers to turn the antennas. The ball bearings are reliable IF you protect them properly. We learned this lesson the hard way. After almost three years in service, I feel confident sharing our solution for adequately protecting the SKF bearings on antenna towers.

My thoughts on Amateur Radio & Software Development
I designed an enclosure and EMI filter for slightly modded HP Server Power Supplies giving them a second life in our ham radio shacks
