Re: LW-MW-SW Relay Tuned 15' Noise Reducing Vertical Antenna

Hi Paul, I wish to correct my statement on the abnormal difference in sensitivity between the HI Z and the 50 Ohm input. This has been caused by an unsuitable transformer used on the 50 Ohm input, because being far from home I have very limited resources here. I hope to get suitable 50 Ohm transform...

Re: Diversity - how does it work?

Look here: https://www.sdrplay.com/community/viewtopic.php?f=7&p=16068#p16068 You must go click on SINGLE it will open up so you can click on DIVERSITY. Then it will be all automatic, provided you have two different antennas, one for each 50 Ohm tuner input. You will not believe it, it takes tim...

Re: LW-MW-SW Relay Tuned 15' Noise Reducing Vertical Antenna

IMPORTANT Paul I have discovered that I have the best performance using the HI Z input, as I have been doing since yesterday evening and using the following low noise transformer: Toroid core: FT-37-43 (material type 43) Ext. dia.: 0.375" Internal dia.: 0.187" Thickness: 0.125" PRIMAR...

Phil,

It is really rewarding to have around a guy like you. Nothing can substitute experience and your experience in antennas is a great gift to all of our Community Forum. Will surely pester you in August, when I come back. looking forward to setting up this giant square!

Re: LW-MW-SW Relay Tuned 15' Noise Reducing Vertical Antenna

Paul, I will be very glad to hear about your experience with this simple antenna. The only important thing for success must be elevation and in this my setup is OK, because I am three storeys high, or up about 16 m. Superior performance is with the antenna in horizontal position. In vertical positio...

Re: GETTING READY FOR RSPduo DIVERSITY SOFTWARE

THE DIVERSITY AGE HAS ARRIVED! Figure 4 shows RSPduo Diversity on left laptop and control RSP-1A in operation on right laptop. Figure 5 shows the antenna interconnections. To minimize PC generated interference, the RSP's are remoted. Finally Figure 6 shows a -117 dBm signal (invisible on the displa...
