My Ham Radio Logbooks

This is the first page of my very first amateur radio logbook. My first amateur radio contact was with Anders SM5DOP answering my CQ on 144 MHz on 2 Nov 1971 (38 years ago). My QTH was Trångsund near and south of Stockholm. My equipment was a Heathkit HW17 transceiver with FM modulation and 10 W input transmit power. This transceiver with its superregenerative receiver was called "Blåslampa" in Swedish. The antenna was a Halo antenna. SM5DOP´s QTH was in Södermalm in Stockholm, so the distance was not very far between us.

Since many years my logbook is of course computerized. Now I am using the Ham Radio Delux logbook software developed by Simon HB9DRV. See some of the user interfaces above.

With the Ham Radio Delux logbook you can perform an analysis of the logbook content. Here is the link to where you can download a detailed analysis of my logbook since 26 December 1993:

Spectrum Analyzers

A spectrum analyzer should be part of every ham´s toolbox. That for easy checking what is going on inside a radio, transmitter performance, filter response, antenna matching, cable losses etc.. But the price tag puts of course a stop to this. Those who absolutely need such instrument and cannot afford a new instrument have to find a cheap old used one. But those working with very high frequencies are not cheap either.

PC USB connected black box analyzers are becoming lower in price and also stand alone very competent analyzers. The reduction in price is because of more and more advanced hardware and software

A recent example of a spectrum analyzer with astonishing relatively low price is the Siglent SSA3021X (9 kHz - 2.1 GHz). For example if equipped with tracking generator (software option) and a VSWR bridge for antenna measurements it cost less than a better transceiver. This analyzer has been tested in ARRL´s lab (QST Nov 2016) with good results. Before the test ARRL let Essco Cal…
