RSP2Pro Configured for Inmarsat L-Band

Greetings, A few test sessions ago I constructed what I have labeled as a 'Cantenna Helix' which I then used to signal feed the RSP2Pro tuned to a swath of L-Band Inmarsat Frequencies. For those Forum members whom are not 'Tweeters' , out of courtesy i decided i would, (as i have been doing since i ...

Re: RSP2PRO..Its a W.I.P...Work In Progress

Thanks for that bit of nfo Roger, I may have a copy of that version of SDRSharp. However I don't think that by reverting to that version will help me to catchup on my backlog of work. I am all about Moving Forward.My initiation using SDRSHARP has armed me with the confidence to engage in 'Moving For...

Re: RSP2PRO..Its a W.I.P...Work In Progress

Greetings, I have been subjecting my RSP2Pro unit to a myriad of signal monitoring configurations. It is definitely not a 'Toy' in the true sense of the word..a very professional unit capable of being 'suited' for a wide range of purposes. Basically i am still getting familiarized with the various S...

Re: New product availability?

Greetings, Just read this announcement via Twitter regarding the theft of SDRPlay products.What a bummer that is. https://twitter.com/SDRPlay/status/997050175272169473 How does that situation affect the availability of the RSP2Pro? I am about ready to order another one of your units,is there a wait ...

Re: Antenna Recommendation for L.E.O LRPT

Greetings. After wireing the connections to the QFH i performed a set of active RF test to determine the resonant frequency of the Build. https://twitter.com/fearlesslyloyal/status/968565374672429057 I was surprised when i found that the unit resonated at 128Mhz https://twitter.com/fearlesslyloyal/s...

Re: Antenna Recommendation for L.E.O LRPT

We have been taught the Theory of Reciprocity which states that the receive and transmit properties of an antenna are identical. I was fortunate to have been provided the opportunity to construct quite a few Circular Polarized Aerial systems for FM Broadcast Curious how such a circular design radiat...

Re: Antenna Recommendation for L.E.O LRPT

Greetings. Thanks comrades Mike2459 and NOBGS for the recommendations. Yes i have read about all those designs, actually i have compiled quite an extensive list of construction articles related to Weather satellite reception. The Double cross Antenna is definitely among my picks and have started to ...

Re: Antenna Recommendation for L.E.O LRPT

About 15 (or more) years ago I built a QFH for the 137 MHz band from a broomstick, some plastic rods, 75 ohm coax and a few cable ties to hold the coax in place. The hardest part was soldering the steel coax shield. I had to use acid core solder. Used an inline TV signal booster as an LNA. It's mou...

Antenna Recommendation for L.E.O LRPT

Greetings, I am presently narrowing down which design(s) i ought to use for my Weather Satellite and Earth Observation projects. I have been reading quite a few design notes published on the Internet.There seems to be a lot going for the QFH . a)Compared to the other designs such as Turnstile/crosse...

Re: RSP2PRO..Its a W.I.P...Work In Progress

I have been using the RSP2-PRO to monitor a few frequencies. used for NOAA weather satellites 137.5Mhz and also 1.707Ghz for local terrestrial interference. From prior SDR Stick use, I have seen quite a few cases of RFI from local terrestrial emissons.So i have been 'looking' at the spectrum around ...
