The radio can receive between 5.800 MHz and 6.200 MHz in AM-mode.
Besides the normal radiostations I wanted to see if I could hear the D.A.R.C. (Deutschen Amateur-Radio-Club) 10 kW shortwave transmitter on 6.070 MHZ from Ingolstads in Germany. They also make use of the big shortwave station in Woofferton in the UK on 9.670 MHz.
You can get all the parts, sorry no sigarbox, at box73.de and they have a radio for 6.070 of a radio for the 2 frequencies the D.A.R.C. uses.

![The SWR Indicator
Its a small device that shows if your swr [ standing wave ratio ] is ok. You place it between your transmitter and an antennatuner or antenna. If the led glows very low than your swr is ok but when the led shines brightly than the swr is very bad and than you have to retune your antennatuner or adjust your antenna.
It uses the reflected inputpower from your transmitter via de diodes. The diodes act like a rectifier so no battery of powersupply is necessary. Always use low power [ 5 Watt of less ] to protect your transmitter. If all is well just switch the swr indicator on through of disconnect the swr indicator.

UVB-76 (sometimes referred to as UZB-76 is the call sign of a shortwave radio station that usually broadcasts on the frequency 4625 kHz (AM suppressed lower sideband). It is known among radio listeners by the nickname The Buzzer.
It features a short, monotonous buzz tone, repeating at a rate of approximately 25 tones per minute, for 24 hours per day.
The station has been observed since around 1982.
On rare occasions, the buzzer signal is interrupted and a voice transmission in Russian takes place.
Despite much speculation, the actual purpose of this station remains unknown to the public.
