Re: Buzz in AM mode

Hello Paul, This problem can occur if you have a coaxial feed cable that runs close to mains wiring. We have seen people able to couple several volts of signal on to the shield of the coaxial feed cable. The problem is usually more prevalent on port A than on port B. This is because port A has a bet...

Re: RSP2 Band Pass not working?

Hello Phoenix, What matters is the frequency of the LO, not the VFO. If your Tetra signal is at 397.74 MHz, if the spurious response is cause by mixing of this signal with the third harmonic of the synthesizer, then if you set the LO to 132.58 MHz, I would expect the ghost signal to sit precisely on...

Re: RSP2 Band Pass not working?

I should add, that if your RTL dongle uses a Rafael Micro tuner, it uses a low IF architecture whereas the RSP uses a zero IF architecture. This means that that your RTL dongle will still have a spurious response withyour Tetra signal, but it will appear in a different part of the VHF spectrum. If y...

Re: RSP2 Band Pass not working?

Hello Phoenix, If you are using SDRuno, please measure the power of both the original Tetra station at 390 MHz and the Spurious response at 130 MHz. Such spurious responses occur because the Synthesiser is tuned to 130 MHz and it has a 3rd harmonic at 390 MHz. This third harmonic will mix with the T...

Re: RSP2 with SdrSharp

Regarding SDR#, this has been covered before ad nauseam. We would love to support SDR#, but it is not within our gift to do so. All attempts to collaborate with the authors of the software have been rebuffed. Please check through the various threads on the subject. Regarding SDRuno, we will have a n...

Re: RSP2 with SdrSharp

Hello Phoenix,
If you can get hold of release 1361 or earlier, you can use the RSP2 via the ExtIO plugin. After release 1361, it is not possible to use the RSP2 with SDR#

Sincerely

Re: SDRuno and DAB FM Digital Sidebands?

Hello Phil, I am afraid that we still don't have a schedule for incorporating DAB within SDRuno, but I can assure you that it will get done. Unfortunately, I cannot say when as we have a long list of features and improvements to make with SDRuno. In the meantime, you might want to look at SDR-J as i...

Re: Request for clarification of s/w authorship

I should also add that the APIs supplied for the RSP will almost certainly not work with non-RSP devices, even I they do use the Mirics chipset. That is because there are a range of auxiliary control functions in the RSP that will not necessarily be available with other devices. Sincerely SDRplay Te...
