Re: "Low Noise" Vertical Antennas for Receiving
Bill I'm glad to see someone else give Lankford the respect that he deserves. I found his articles on flag antennas arrays particularly interesting. I'm responding to your request in the earlier DCF77 thread: "From what I understand you have designed an active antenna and I hope you can post a littl...

Re: AM Broadcast Stations on 22 MHz
That should work. I had problems on longwave with out of band HF and MW signals. I built a 3 pole elliptic LP filter in an Altoids can for the HiZ port that cuts everything above 520Khz. Works great, virtually no OOB stuff, it also lowered the noise levels somewhat on LW.

Re: DCF 77 77.5KHZ
There is a gentleman from NZ on the NDB list who has received the carrier of DCF77 there. He must have a very quiet location to work from.

Re: AM Broadcast Stations on 22 MHz
Here in the US Par Electronics sells them. They also will make custom filters according to their website. I don't own any of their products. http://www.parelectronics.com/index.php and DX Engineering https://www.dxengineering.com/parts/hiz-hpf 75ohm connectors for Hi-Z antennas Try a google search "...

Re: AM Broadcast Stations on 22 MHz
Amazon sells them for 16.95USD, but the 3db frequency is 2.5MhZ which would attenuate 160 Meter band, they have SMA connectors.

Re: my problem with ..uno
From what I can tell by viewing the audio spectrum with PDBPF filter on and off. It acts as a low-pass filter with a cut off around 8 kHz

Re: A FOOLPROOF ANTENNA SWITCH
Years ago I purchased a new Akai reel to reel stereo tape deck. It had many features. One of them was auto-reversing. It enabled playback of a full tape, both sides without the need to remove the full reel flip it over and place on the right capstan, and rethread to the empty reel. To accomplish thi...

Re: AM Broadcast Stations on 22 MHz
If you set your SDR to 24000000 (24 mhz) you will be tuned to the SDRplay's local oscillator (within a few hertz). Center this frequency in the screen, enter ZIF mode & select a sample rate of 4.0 mhz. You will see any image products generated from 0 to 2 mhz starting at 24mhz up to 26mhz with a mir...
