Welcome to the Club / No QRO please
« Last post by PA1CJT on October 26, 2019, 05:32:57 UTC »
Dear all,
I noticed, looking around the website, that it is common that new members introduce themselve with a small or perhaps larger 'Who am I'.
The subjet is 'No QRO please' but QRO is not for everyone the same. I have a QRO radio (FT-7) but others say it is QRP. My name is Kees and my callsign PA1CJT and living in the western part of the Netherlands. I am licensed since 1981 and had severall callsigns before. Still working for a living and no place the build up a large antenne causes lower activities on HF and VHF. My antenna is a home made magnetic loop which covers at least 40 - 12 m bands and and onther antennas are really QRP build (dipole, end-fed etc with max power 10W). It is again fun to build these antenna's and go out in the field to make some QSO. I made US contacts just with 2,5 Watt portable so yes it works fine for me. Instead of powers is operating practise teh message. First I start listening to the station and even pile-ups I can win with QRP jut waiting for the right moment knowing how thw other side operates his or her station. Wash all readers of this intro lots of fun with QRP. 73's de Kees

I posted my introduction spiel this morning, and just noticed that the most recent post in this forum before mine was back on June 20.
Did everybody moved to another forum? or is QRP moribund?

Very little being posted for the past year. I used to look in frequently and tried to keep things going with the odd post, but it's starting to look rather dead now. Rather a shame as it was a very active and intersesting group when first established.

Builder's Corner / A Chance Crystal Radio Project
« Last post by vu2nan on August 19, 2019, 16:26:18 UTC »
A vintage unmarked inductor/transformer had been lying neglected in my junkbox for decades and I had to resurrect it.

Resistance checks showed that 2 windings, with a tap each, are terminated in its 6 pins. One measured 70 Ω with a 5 Ω tap and the other less than 1 Ω. A threaded core, with a movement of 5 mm is situated at the top of the unit.

The 70 Ω winding appeared to be suitable for a crystal radio. It was wired up as per the schematic shown below.

Builder's Corner / Tarnished Silver as a Crystal Radio Detector
« Last post by vu2nan on August 19, 2019, 16:05:36 UTC »
A fully tarnished, shiny black silver artefact was tried out as a detector in place of the germanium transistor in my series-tuned, shunt-fed crystal radio.

Builder's Corner / Carbon Microphone as a Crystal Radio Detector
« Last post by vu2nan on August 19, 2019, 16:01:59 UTC »
A vintage telephone carbon microphone, which possesses multiple contacts between carbon granules and metal, was tried out as a detector replacing the germanium transistor in my series-tuned, shunt fed crystal radio.

I retired last week and decided to come back to ham radio, QRP to be specific.
I found out my CW is a little rusty at 20 wpm (used to good at 25 wpm). but will catch up soon.
Using a Heathkit HW-9 and a Vibroplex Champion bug.  The  antenna is a Butternut HF-6V and it isn’t quite tune in yet.
