Re: Radio "limbo"
Some final comments on my "radio limbo" experiment. I've left it running since October 7th and will shut it down today (October 17th), in order to reclaim the step attenuator I've been using to

Rolf,
I am using three different amplifiers built by N4CY Everett Sharp. They all are 11 dB gain. He has changed the version several times, one has a relay to disconnect the antenna when no power is

Re: HB9VQQ testing Kiwi SDR
Not sure I’d consider myself a big gun, but I have had very good results with high spot counts.
I am not using any and pre-amplification on the resonant antennas.
The only antenna with a pre-amp

Re: New install on Pi4 question
There is also an access speed issue that the ram disk helps.
this line needs to be added to the end of your /etc/fstab file
tmpfs /tmp/wsprdaemon tmpfs defaults,noatime,nosuid,size=300m
