Re: NOISE ADVANTAGE OF LONG WIRE ANTENNA FAR END TERMINATION
Glovisol it looks to me perhaps there is something wrong in your results. If you have a more sensitive antenna, it will also pick up more noise as well as the signal, just as Mike2459 shows in the reference in "Receive antenna & impedance "matching". Also I do not understand what you mean by counter...

Re: RSP2 + gnuradio + airband = no big success :-(
Hi Raymond, it is my experience that in many areas giant FM station signals do exist and they can badly overload and / or desensitize the RSP receiver. Make sure you use the FM notch when on the airband and if this is not enough use an external filter to blot out the FM band completely.

Re: Using two coherent RSP2's
Being aware of all material published by Sdrplay on the diversity issue, in my opinion the two units within a single RSPduo are coherent, as intended for your work, but these two will NOT be coherent with the other two receivers of another RSPduo, even if you use the same reference oscillator signal.

Re: FT 990 IF output
In some Yaesu units the IF rides on 9 V d.c. better check. If this is the case you can isolate with an in between capacitor. Your RSP measures the power level it receives very accurately in dBm, so you can immediately judge if you are safe or not. You approach the safety limit with 0 dbm and you CAN...

Re: Ant Input: RSP And RSP-2 Ant A Input ?
Hi Bob,
I see from your posts you are jumping from one software to another practically every day, while you did not report if at least you now work with your RSP2 and SDRuno without problems...I wish to help if you still encounter difficulties!

Re: RSP1A HF Signals
It will take you 10 minutes flat to download SDRuno and install on your PC. Then, if you still experience low sensitivity as compared to other receivers CONNECTED TO THE SAME ANTENNA AND IN THE SAME WAY, then you should open a ticket, but chances are you have a problem with Console's attenuation or ...

Re: THE POWER LOSS ADVANTAGE OF USING 3 dB COUPLERS
Glovisol, from your calculations it seems that ON5HB, apart strange theories on local oscillators, mixers, RSP receivers, vswr and so on, was not completely wrong in practice, after all!

Re: Receive Antenna & Impedance "Matching"
I am glad to be your source of amazement and wonder, but , Mike you should not change the object of your discussion with every new post...you start by splitting hairs on receiver's input impedance and end up, on your last instalment on radio know how, with advising the obvious.....A new Monsieur de ...

Re: Receive Antenna & Impedance "Matching"
Antenna and/or receive impedance is an important parameter, regardless of the concerns of Wellbrook antenna users. As far as receiving signals buried in the noise, the issue here is to use the right level of gain, or attenuation, as the case may be, but this has nothing to do with impedance. If you ...

Well done, glovisol, I think it could not be explained simpler!
