Re: SDRplay 2 TCXO PN and external locking

Hi, yes it all works perfectly well thanks. Thanks for clarifying that there is a switch and not a PLL operating on the TCXO, I suspected that would be the case. My question is not a 'how to' or operational one but one of performance. I will ask again perhaps a little more directly. Is there ANY cha...

Re: HDSDR, Omnirig and 3 radios

I can ask Alex, he did give me some pointers on how achieve the functionality that I needed. It was quite a copy paste exercise to be honest so Alex can probably just use my code. I will ask him, I am pretty sure that I am not the only one who would like this functionality. You are correct that this...

Re: SDRplay 2 TCXO PN and external locking

OK, I know how to set it up, I have been using it locked to a 24MHz oscillator for quite a few weeks now but I still do not know anything about the TCXO performance. I want to know the phase noise performance of the TCXO and if it is locked or if there is just a simple RF detector that switches the ...

HDSDR, Omnirig and 3 radios

Hello. With the help of a work colleague I have managed to compile an Omnirig executable that works with 3 radios. However HDSDR only shows syncRig1 and syncRig2 as options. The RIG3 tab is available in OmniRig set up and a com port sniffer shows that the port is indeed active. So I assume that HDSD...

Re: SDRplay 2 TCXO PN and external locking

Did I post this in the wrong place, nobody has anything to say about this? I am overwhelmed to be honest.

Re: SDRplay 2 TCXO PN and external locking

I found the schematics here: http://sdrplay.com/docs/SDRplay_RSP_Schematics_r2p2.pdf So I see from this that the TCXO is not shown as such, rather a simple Xtal oscillator. The datasheet shows a TCXO and I have found the frequency accuracy to be quite good out of the box. What is also not evident on...

Re: SDRplay 2 TCXO PN and external locking

So this information is not available? Ok then I will measure it myself.

SDRplay 2 TCXO PN and external locking

Hello all, I have 24MHz GPSDO. I was wondering what the PN of the internal TCXO is, just to ascertain that my 24MHz TCXO will not degrade performance significantly. I am just running the 24 MHz oscillator on an FSUP to measure the PN this afternoon. I presume that there is a PLL on the TXCO when an ...
