Title: VLF station test from Sweden Post by: Bill, KD0HG on December 05, 2008, 12:41:32 PM SAQ, the very old wireless station in Sweden on 17.2 Khz (no typo) will be on the air this weekend. Mode is CW and power will be 200kw using an Alexanderson alternator.

Good time to check out my newly completed R3090 VLF RX that tunes 500 Hz to 500 KHz Title: Re: VLF station test from Sweden Post by: Todd, KA1KAQ on December 11, 2008, 02:01:48 PM How did this work out? Did anyone copy the broadcast?

My sdr set up had a spur right in the wrong place. I need to change the crystal on my QSD converter to move the spur. The R3090 on 17.2 KHz. I thought I could hear something but could not copy it with a 100 uv noise level. I turned off the agc to hear it. I need a better antenna. I was using the center fed inverted L for 75. I need to put up a k9ay or something similar to reduce noise. OTOH Jay W1VD was strapping at 1000uv on 600m Tuesday night. VFL is a different animal. There are some strong signals below 100 KHz. |
