0410 Hello Redhat. I have you in stereo. Sounding great.
Shortwave Pirate Radio In North America And Around The World, And Other Signals That Go Bump In The Night
We seek to understand and document all radio transmissions, legal and otherwise, as part of the radio listening hobby. We do not encourage any radio operations contrary to regulations.
Always consult with the appropriate authorities if you have questions concerning what is permissable in your locale.
As you already know. This is just for others.
The best way to keep SDR’ S on frequency is to use a GPS clock frequency source (as done on kiwi’s) if they have a external clock input or a calibrated TCXO OCXO for example. The better SDR’s do. I am amazed by some of the SSB (not AM) recordings I receive off frequency that the listeners think sound good.
The R-75 has 3 stock filters 15k 6K 2.4K. If properly set up in the filter selection menu (see operation manual) you should be able to access all of them. You likely have it set up wrong. If a filter is selected to off (in the menu) it will sound muffled. The 2.4K filter is to narrow on AM but is still useful on very weak stations. If you off tune the AM station you should hear a difference between the 15K and 6K filters when switching them. I found that my R75 was not set up correctly. Now I have all 3 filters working as W-15K, 6K, N-2.4K. Also if you can get a used or old new stock DSP it works very well.

It is nice to see the relay station on the air again.

You can see it drifted up in frequency after it signed on, probably thermal drift in the oscillator.

Equipment / Re: ICOM ICR-75 vs. TECSUN S-2000
« on: October 08, 2020, 1808 UTC »wondering, if your R75 has the DSP installed. Unfortunately mine doesn't have the DSP, and I wonder if lack of DSP in the set makes the narrow filter sounds muffled.
Yes, my only problem with the R75 is that, when the narrow filter is selected, the audio becomes awfully muffled. Due to this, I have been using it with the Wide filter selected only, but many times, I find it too wide, which gives selectivity problems.

My R75 has been collecting dust. I fired it up after seeing this post. It is a very good receiver. Especially for SSB, it needs a TCXO. I need HI FI broadcast audio so I will build a SDR 9 MHz IF board then feed it to a 192Khz sound card with HDSDR with CAT control to sync frequency with the R75. This would make a great setup.

Equipment / Re: Crossed Parallel Loop Antenna - back to passive
« on: September 22, 2020, 1703 UTC »
The S/N factor from the design of this wide band loop antenna is a big factor. Reducing the loops inductance can help. If the gain is not sufficient with your passive transformer you can design a different active per amp circuit with a acceptable noise floor.

How does this loop antenna compare to a single loop antenna? Sometimes with a proper match with a step up transformer you can achieve good gain to the receiver without the added noise of using a matching preamp.

Mostly I do not use a closing song because I play a variety of music genres. In the past I used a nice classical song ‘Con te partirò ‘ or ‘Time to Say Goodbye’ by Andrea Bocelli & Sarah Brightman.
