Hi Paolo, As always, much thanks for help. Old age can be rough, even for the simple stuff. Which Plug-In please ? Regards, Bob

Hi, Looking for some advice. I have made a receive loop antenna using a Hula-Loop and a basic pre-amp circuit. Inside the Hula-Loop I have fed some old mains flex which has 3 x multi-strand conductors. My question is: Would I be better connecting the conductors together in parallel, leaving me with a single turn loop. or Would I be better connecting them in series making a 3 turn loop. My interest is in frequencies below 10Mhz so I am guessing the more turns the better, but this is not a tuned antenna so I am unsure. Just some simple advice please. Thanks Martin

Dear All Beginner here so apologies if my newbie question is a tad naive. I've been using SDRSharp for sometime just to explore the AirSpy network and mostly for monitoring RTTY signals. I would like to know if there's any way to connect a cheap external oscilloscope to display the mark/space ratio (the two elipses at right angles)? Alternatively, is there a software app that looks like a real oscilloscope that would do the same thing? I realise that most SDR programs have some sort of scope display built in. I'm just wondering if there's something better that can be plugged into say, the audio repeater software. I used to use a cheap external scope in the old days with a Yaesu FRG 7700 using the audio feed. I really miss the physical buttons and knobs! TIA Trevor

How to add a new Tetra plugin for version 1920? I have plugin files and a line that used to be added to the Plugins.xml file. I will add these files in this discussion thread. The plugin decodes Tetra's voice well, better than what is currently in the package. Could you please tell me in detail how to add it? Thanks. Magic line: <add key="Tetra1" value="SDRSharp.TetraNetMon.TetraNetMonPlugin,SDRSharp.TetraNetMon" />

Building on the previous thread, I intend to try to build some more antennas in terms of mechanical engineering to maximize strength and convenience and minimize cost. I am perfectly aware of hula hoops and rigid steel and pex and even corrugated waveguide based options. https://www.amazon.com/Nets-More-Fiberglass-Captain-America/dp/B097NMT4YQ nets and more sells a reinforced nyglass hoop design for use in craft projects. it's a little bit small, but i'm requesting their larger 30 inch diameter hoop via email. to go with it i made some clamps. I was able to get this made in the usa of nylon 12 for $14 each shipping included through craftcloud3d. I opted to order the simpler build I made first because the dimensions are more proper(no decimals involved) and it can probably be machined easily if I need more. The more complex rounded design here needs more polish to make it look good, but could save on materials https://www.amazon.com/Qlvily-Stainless-Thread-Threaded-Threads/dp/B0CP8Q669Y?s=hi&sr=1-13 Here is the current design: the saddle clamps are placed around the fiberglass rod and the lamp pipe inserted through the hole and then secured with nuts and washers on both sides. a hexagonal pattern is used with 6 points to secure the hoops together in this fashion. If necessary, I will line or pad the inside surface with rubber or another suitable material to improve the fitting. This will make a very stable scaffold, which can then be rigidly mounted to a pole or on top of a post any number of desired ways by virtue of pure right angle mating surfaces. This is both reusable and extensible. If I for example make a bigger loop out of pex, and want to do a double loop, or otherwise support the loop with off-center rods, such as the fiberglass chimney sweep rods I already own, that option is doable! If you know where I could have gotten these blocks made of nylon 12 for less than $14 each shipping included, I would be interested in finding out. These mounts are the most expensive part of this particular experiment. I have some other block designs I have made in the past for general purpose universal mounts which never made it past the mspaint stage, but they will be bigger and require even more material. best regards

Hi all, I have just received an email from someone called Desmond from theweathergal@... with the text "Screw you and your server". Humm, not very polite, I wonder why. On the off-chance, would Desmond be on this group or anyone know of him? I would love to know what the problem is. The only connection I have to my server is from Russia, (Moskovskaya oblast'), so it could just be random hate or a VPN or the person at this location could be nothing to do with it. Anyone any thoughts?
