Sharing antenna with RSP2 & transciever via MFJ 1708SDR - problem

Hi All I have bought the RF sensing switch from MFJ. However, when keying up (transmitting) I am seeing RF all over the band scope (the SDR is shunted to ground during transmit). It's the effect same with a dummy load. I have posted a video of the issue below. Any ideas/advice on solutions would be ...

Re: Sdruno, IC 7300, MFJ1708 help

Are you guys using the "ORIG" section in the "RX Settings" of the RX Control, or the "cat" menu in that same box? People get confused with those two. Use the "ORIG" tab..(for Omnirig) NOT the "cat" tab. The other thing is to make sure "RSYNC1&q...

Re: Sdruno, IC 7300, MFJ1708 help

Me too! Have FT 840 (got the FTDI CAT cable), MFJ 1708, Omnirig & SDRUNO. Just got everything today and I'm really struggling to get things off the ground. It may something to do with pairing com ports. Have you had any luck?

Re: Balanced Line Sharing of RSP2 with Rig. Yaesu FT 840

Hi Adrian As a newbie to SDR I recommend you use it in listening mode for some time before transmitting into the antenna!. I have been licensed for 55 years and will probably spend the next 6 months using my newly purchased RSP2 to check out RFI sources in the shack. The first RFI problem has alrea...

Not sure how the twinlead is going to connect but look into one of these devices. https://www.dxengineering.com/parts/dxe-rtr-2 http://www.mfjenterprises.com/Product.php?productid=MFJ-1708 http://www.ebay.com/itm/Antenna-sharing-device-QSK-TX-RX-switch-For-SDR-and-Radio/122558706221?ssPageName=STRK...

Re: 1.2 Doesn't work properly - can I download original again please?

Hello Adrian, I suggest that you open up a support ticket. This will almost certainly be a settings issue as 1.2 has a different registry map from 1.13. What I can assure you of is that nothing whatsoever has changed within the core signal processing engine, so if you are having a problem leading t...

Re: 1.2 Doesn't work properly - can I download original again please?

Adrian, Looking at your video, I notice that you have the fatal combination of listening to AM with the receive frequency and the local oscillator frequency being the same. The software that removes the "centre spike" on a Zero IF signal will also remove the AM signal's carrier. Try offse...

1.2 Doesn't work properly - can I download original again please?

Hi SDRplay team I appreciate the time and effort that has gone into SDRUno 1.2. However, it doesn't work properly - I don't know what the issue is and haven't a clue around how to fix it. All I know is that receive quality is significantly degraded across all bands. As an example I have attached a c...

Re: PC (laptop) power induces significant noise

Hello Adrian, The problem you all have is nothing new - it is called EMC. Many devices especially those cheap ones coming from Asia do not fulfil the requirements of the EMC-directive (Europe) or FCC (USA). They produce to much noise on the power-lines, the power-lines radiate this noise and you he...

Re: PC (laptop) power induces significant noise

Thanks DerekR for starting this thread. I have isolated my own noise issues by switching on and off the circuit breakers. There are two offenders: 1. the house alarm (I can switch off the breaker, as I'll be in the house when using the SDR - so no biggie there). 2. The lights in our kitchen extensio...
