> Used to listen to 16 khz from GBR in England on an RAL... That should be the VLF/LF/MF RAK (15 TO 600 KHz), not the RAL, which was the MF/HF companion receiver (300 to 23000 kHz). These 80-year-old-design TRF/Regenerative units were outstanding receivers during their era as the US Navy's principal shipboard set before and during WWII. The RAL still does well today on HF, especially for CW.
http://www.virhistory.com/navy/rcvrs/rak-ral.htm This whole thread was mis-named. The specified frequency of 10 kHz is far far far from ELF. Tbat is merely a Very Low Frequency VLF, 3 to 30 kHz. Ultra Low Frequency ULF is 0.3 to 3 kHz. Super Low Frequency SLF is 30 to 300 Hz. Extremely Low Frequency ELF is 3 to 30 Hz. I doubt that there is a firmware mod that could make the K3S work at ELF, either going in or coming out! :-) Mike / KK5F ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
