New HF Dongle

I came across this and if it,s true about the receiver Sensitivity: being at 0.05 uV at 20M band, preamp = 0 than I think it may be as good Windradio . It has my interest and I am looking foreword to getting one when they hit the market . https://sunsdr.eu/product/colibrinano/?utm_content=buffer3eea...

Re: Have people tried using Satellite TV Switches

The satellite splitter /combiners I think use a voltage to switch to different antennas that is supplied buy the satellite receiver . For myself I use an A/B switch and it work"s just fine .

Re: First timers Antenna and Overall setup suggestion RTL SD

For frequencies above 50MHZ a disc cone antenna it a good choice . Just be careful about the connector that comes with the antenna . You don't want a disc cone that has a PL-259 connector on it . That connector frequency only go's to the high 300MHZ . A disc cone antenna that has a female N connecto...

Re: Direct sampling hardware mode

Hi ClipArt .
If I may add my two cents to this . The 1:16 RF transformer that he is talking about comes from Mini-Circuits it's a ADT16-6T the other 1:16 RF transformer you can use is from Coilcraft and it's number is C 16-A . If you have any questions just do another post .

Re: The V3 Dongle

I would like to add more information that I hope people would find helpful . After playing around with the V3 dongle for a couple weeks I would like to say that the V3 and the MFJ1020c is a very good match . The reason why I say that is that MFJ1020c is only pre-selector that can attenuate a strong ...

Now MFJ makes other pre-selectors MFJ-956 Pre-Selector/Antenna Tuner , MFJ 1045C , MFJ 1048 , MFJ 1046 , some of them don't have a RF Amp in them . Their are company's in Europe that make ham equipment also pre...

The V3 Dongle

I would start out by saying that I am in no way putting down the V3 dongle at all . I think the people that engineered it did a good job ,I like that they did it as a direct sampling dongle . I like that they have a -10 db amp. in front of the RF transformer. Because of the lower noise I am able to ...

Re: Does the RTL SDR also function as an antenna tuner?

SlowBro Just so you understand I am talking about frequencies that are in the 160 meters 80M 40M 20M 17M and 15M . This is were the MFJ 1020 works with a direct sampling dongle . The 1020 isn't a antenna tuner , its more a preselector . This is a Quote from a friend by the name of Martin Ehrenfried ...
