Hi Ralf, I agree, but I do not see your location in your post. Better you omit the useless we from the PC screens. Much better see large so with received levels & noise level floor. So from where you receive?

Hi glovisol thanks for the info!

Very clear glovisol! Give info about Balun for rsp1a in the photo, thanks

Hi Arcosine what is your receiver the 1a or the duo?

Hi ON5HB, you mean I do not need such sensitivity & the 1a is O.k.? For me one input is O.k.

Thanks!

Hi glovisol thanks for the explanation.

Hi Roger, I really appreciate your help & work to give info! I wait for next post before choose it.

Thank again guys

Guys I want to buy a Rsp and now I am confused: must I get the 1a or the duo? For glovisol the duo is more sensitive by 35 db, very good. For Roger it is 123-101 = 22 db, good in one post and now is 14 db, not so hot in the last post. But the 1a is far cheaper. Can someone explain and help?

Hi z inputs cannot be compared with 50 ohm in of rsp1a. Better compare 50 ohm of all sets to have best idea.

Do not take chances with unbalanced connections to the AC line. Use a small step/down transformer PRIMARY: 125 V Secondary: 5v Use one decoupling capacitor on each lead of the secondary, then a balanced H resistive 30/60 dB attenuator to the balanced input of the RSP. If signal still too strong, inc...
