Re: HIGH PASS FILTER FOR OPTIMUM HF RECEPTION

Responding to the original post of the thread.. For the one scenario I didn't see, 500 ohm longwire and 50 ohm radio. Would I build a 500 in/500 out filter with a 500/50 transformer on the output of the filter or a 50/50 filter with a 500/50 transformer on the input of the filter? Or can it be done ...

Re: Is SDRuno C++

OK. Thanks. I guess I'll have just have to live with the minor inconvenience. Other than that, keep up the good work.

Is SDRuno C++

A friend of mine knows C++ and said he would spend an evening but no more to see if its within his skills to implement this. There is a small,but important to me, feature I would like added to my SDRuno program. I like to keep my main spectrum display baseline at the bottom of the window to get best...

Re: AM modulation monitor software

Just to clear any possible confusion, the program in question is only the upper left corner window. SDRuno does not monitor positive and negative modulation peaks and display them separately in a meter or bargraph form. That is the main function of that program. It has nothing to do with frequency o...

AM modulation monitor software

In the link attached I see this modulation monitoring program working alongside an SDR program. I was wondering if anyone out here knows of another piece of software or one being developed that might be cheaper than the REA setup in the vid and would be compatible with the SDRplay. For what it does ...

Re: Gain Reduces When Centering Signals In HF

I can confirm the issue. VFO and FREQ are separated by 80khz. I monitored an unmodulated carrier 1460khz with zoom all the way out which put the signal at the right 1/3 of the screen. Mouse pointer at the very top of the signal spike and numeric display on the left of the main screen matched at -50d...

Re: Update SDRuno issue

I have an RSP1 and running 1.22 Is there anything to be gained by installing 1.23 or 1.24 I haven't been on these forums much lately and from what I have read it doesn't seem so. Have we been forgotten? When I bought my unit a little over a year ago there were a lot of suggestions from users for upd...

Re: SDRuno: best settings for AIS decoding?

I am receiving small blips at those 2 frequencies so I assume those are the AIS signals. I'm about 7 miles west and uphill from the Lake Michigan shoreline in Milwaukee with a 2 meter antenna at the top of my 40 foot tower. So I'm probably set up for good reception. What type of messages are you dec...
