Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
Think with your own head, do not believe in false prophets, trust what you measure and see...I have gone to walk the dog...take it easy.

Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
Funny is, I installed and MFJ SDR-switch the other day, the RSP1A's have the same signal as before, but the Icom7300 dropped by 10~20db in reception. Why did the Icom drop and the RSP1A's didn't? Bas, it is the rsp1a magic....It receives better because it has no mixers... : :oops: In fact where Sdr...

Re: 75/50 ohm for RSP1a connection
For FM signals are generally so strong you can take the mis-match loss between 50 and 75 Ohm and safely connect the antenna to the rsp receiver. Remember though that it should be advisable to have some protection in between, should you have lightning nearby and related induced transients. A small ch...

Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
The right reply is that nobody in his senses would use a 50 Ohm connector on a 75 Ohm coax....come Mike, stop this nonsense and have a peaceful Easter,

Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
Hi Mike, in the same sentence you say that in the spec SRDplay states for "Connectivity" e.g. "input" is: "single 50 Ohm RF connector" and then you say that 50 Ohm has not been specified? Next time you are going to tell us about flying horses? In the same vein then Sdr play does not specify the rece...

Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
Bas, First I asked you to state what splitter you were using, so you could find in the forum somebody that could help you sort out your problem, you did not even reply on the point, sure you know it all already & you do not need any advice. My dear Sir, electronics is science, radio communications i...

Re: Metal Case for RSP1A
Some time ago I saw boxes for the rsp1a sold on eBay, try there.

Re: LOW PASS FILTER FOR OPTIMUM LOW FREQUENCY RECEPTION
Hi glovisol, the filter looks good, but in the response pics I see glitches that look like signals to me. Shielding does not look so good even if you use a metal box

Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
What do you mean wrong info and specs? It's not a transmitter but a receiver, as such impedance isn't crucial to good workings. Exactly what I wrote. The official published specifications by Sdrplay say: 50 Ohm input impedance. If you write in so many words it is not so, you are being unfair to Sdr...

Re: 3 dB HYBRID COUPLER/ISOLATOR FOR ANTENNA SPLITTING 100 KHz -10 MHz
It could help to know what splitters you are using. The RSP1a input is rated 50 Ohm, why should it be different? Why should sdrplay give wrong info & specs?
