Antenna preparation – cables and plugs
A lot of work goes into getting antennas up and running. First, we have to solder plugs onto the end of our coax cables.… Read the rest

Listening is fun too…
Since I do not yet have my license, I listen a lot. Today I made use of one particular feature of the IC-7300 receiver, namely the ability to decode telex (or RTTY) transmissions. I thought this was fun, because I worked with telexes in my time in the military. See… Read the rest
Antenna preparation
Today, my son in law brought me a piece of 7 meter (21 feet) scaffolding pipe. Together we mounted two brackets to the wall of the house. The brackets need to extend 0,5 meter to allow the mast to go past the gutter.

Radio manuals
Together with the ICOM radios we get the ‘basic manual’, which is okay to start with. But soon one wants to dive in a bit deeper and investigate the more advanced functions. For that purpose one can download a PDF file from the ICOM website, for both the IC-7300 and… Read the rest
HAM shack
Made a little riser so the Power Supply Units could have a spot below the radio’s. Nice huh?… Read the rest
Antenna Matching Unit
1.
Today I came across a second hand manual antenna matching unit (an MFJ-971). It can alter the inductive and capacitive impedance of antenna’s so they match impedance of the transmitter.
For a description, see this page.… Read the rest
New radio’s
Yesterday at HAMshop in Maarsen I picked up my new radio’s and unboxed them. Today I’m looking at all the settings, browsing through all the menu’s. The combination of these two radio’s covers all of the legal amateur bands in the Netherlands.

First satellite image!
Today I captured my first satellite image with my SDR. It is a picture that was scanned by the NOAA 19 satellite (ch 1-4, northbound 10E) at 2021-3 -26 14:39 UTC. The pass took about 20 minutes.
Granted, the quality is not yet very good, but when you look carefully,… Read the rest
Radio & satellite tracking
With my new SDR (Software Defined Radio) I am able to listen to radio transmission ranging from 1KHz to 2GHz. This includes most amateur bands, long wave, short wave, HF, VHF and UHF. That’s a lot of options! The radio is a RSPdx from SDRplay:
I started out simple by… Read the rest
