Re: AM Broadcast Stations on 22 MHz

I did the same and the results were excellent. As I like to listen to the sub 100kHz band, I built another LPF specifically for it and the noise level dropped by about 10dB and the images from MW disappeared. IIRC (I never make notes), mine is a two section Chebyshev. It's amazing what signals have...

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. Thanks again Mike I will take a look, appreciate your help. The ones I have seen so far also effectively knock out long wave bands to. I think maybe the best ...

Re: You must enter at least two poll options.

Still happening.
Not sure why it is happening here, I have a phpBB forum and have never had this problem.

Thanks, so I am guessing with this I would not use the HiZ port and just into the SMA Ports on the RSP? Obviously I would need to get a balun for the long-wire then.

Yes, use a high pass filter, as shown here:


Silly question maybe, is there anywhere I can purchase a hp filter, or at worst someone who constructs them?

Re: AM Broadcast Stations on 22 MHz

You should not see this issue with newer models, where the design was improved to address this issue and as observed by others, an external HPF will resolve this issue on the RSP2 I have an RSP2, which I brought about a year or two ago, can't recall precisely right now. Re MW on 22MHz, it was purel...

Re: AM Broadcast Stations on 22 MHz

Hi VK3MHZ, Yes, use a high pass filter, as shown here: I forgot to mention a very, very important point. If you use an antenna amplifier or an amplified antenna ahead of the RSP receiver, it is very likely that the spurs you experience could be generated inside these amplifiers: then it is evident ...

Re: AM Broadcast Stations on 22 MHz

I have 22MHZ loaded with images at night from the AM BCB. I'm using the hi_z port. I was going to say use mw/fm notch filter. I just tried that after switching to the A port on the RSP2. That doesn't help a bit. Wondering why. That gonna be just great when good propagation returns. Mike, this was d...
