Finally, thanks to Stefan DK7FC, I’ve my first “human” signal on 8 kHz band. Stefan was active for all the last week-end on the band to give me a chance to receive his signal, and pixel after pixel the signal apeared in this way: A well marked peak exactly on 8270.005 Hz shows the integration […]
Ready again to receive VLF with my new loop. At the moment the antenna is located on the roof under the TX antenna for MF-LF.
The preamplifier circuit comes from the easyloop of VLF.IT with an OP27 and few others components.
The antenna is composed by 32 turns of 0.15 […]
Tonight I’ve decided to try QRSS on MF and while I was transmitting I’ve seen on DK7FC grabbers a strange signal between mine and IK1HGI’s. The call was C7MW which prefix is allocated to the World Meteorological Organization. With Stefan’s RDF spectrogram is possible to see on the next picture that signal comes from E/W direction.

This is my umpteenth upgrade to the TX antenna to try to get better general performance and get the possibility to work on 136 kHz without tons of electrical wires outside the terrace. The new layout is drawn in the next basic picture: I’ve passed from 4 top wire and a single vertical […]
To make a clean sweep of spagetti wires on the bottom of the antenna, to make my XYL happier, i tought to use the aluminium strip for the first section of the TX antenna.
After removed copper wires I connected the variometer to an old 4 el triband yagi for HF aluminium boom by a […]
In the last weeks I’ve tested a new antenna for 630m band. To have also something usefull for 2200m I’ve built an helical loaded vertical antenna followed by a 3-wires hat, so to have a longer radiator that resonate about on 350 KHz.
The coil was about a 45 meter long 3 cm aluminium […]
Tonight was the second night for my new 630 meter antenna test. Thanks to the increase of Lowfers fellows I’ve had the possibility to have more receivers that last year. I’ve been listened by about 40 different stations in more than a dozen of European country.
This image is relative to the night between […]
Wandering on the Internet I found an interesting LZ1AQ kit about a broadband antenna amplifier for small antennas.
I immediately felt that it was a great product also saw the multitude of schemes and research carried out by Chevdar. I then bought a kit AAA and started with the construction of the antenna. These […]
Here is my result for the 2015 CQ WPX Contest. 80 meters QRP is really hard to do with minimalist vertical antenna. I achieved something beyond my expectations. See you in the CQ WW CW at the end of November.
