Re: Testing RSPduo receiver sensitivity with noise generator

Dear Phil, it is 18:00 hours and I am back (tired) from the Riviera. Tomorrow I shall study your material in detail. Here I wish to give you physical details of the Beverage and of my setup, because I fear it is far simpler than you imagined. The antenna is held to the side of the house with a tripl...

Re: Testing RSPduo receiver sensitivity with noise generator

Dear Phil, It is six in the morning here and I have just seen your fantastic response. Unfortunately today I cannot even read it properly, as I have to go to sea, on the Riviera, to bring help to a friend of mine who has burned out the diesel on his sailing boat and I have to go there to see the wor...

An intermittent antenna connection, perhaps?

Re: Testing RSPduo receiver sensitivity with noise generator

More PC screens enclosed. Use of a correctly matched balun lets you use all the sensitivity advantage of the Hi Z input from broacast band up to the 40 m band. By using normal windings on the cores (not wireline) it is possible to keep the Hi Z input balanced as well (terminal "N" floating) and this...

Re: Testing RSPduo receiver sensitivity with noise generator

Dear Phil, Thanks a lot about your offer of assistance, which I surely need. I can see from your photos that you must have accumulated a big experience! The necessary complement to a Beverage antenna is a properly working balun. To feed an RSP type receiver we need a nominal 600 Ohm antenna input to...

Re: Sdrplay rsp1a signal meter calibration sdruno

Hi Mr. Paul, as far as I can see the S meter DOES NOT NEED TO BE CALIBRATED at all: in my RSPduo and even in my previous RSP2pro the meters show EXCELLENT & STABLE calibration to the dBm table!

Kinds regards,

Re: Testing RSPduo receiver sensitivity with noise generator

Hi Phil, Glad that Tech Support put the decimation issue to bed. As I wrote you yesterday, I was initially very curious about it, and tried to discover differences in sensitivity, while with very weak signals from a short antenna, but did not discover any. Now I understand...in order to kill leakage...
