How hard was to create a VOR receiver with GNUradio? I really like the idea, but I found GNUradio very difficult to learn (and I have a master degree in Telecommunication Engineering). The basic things are easy, but when things becoming com

What always surprises me on the ham world is the huge number of possibilities. Beside having voice QSO in HF or VHF, there are many other options: QRP and SOTA/POTA, digital modes, DYI antennas and radios, SDR, EME, identifying unknown

As Italian, I really hope so. Our green party and ecologists raise a lot of terror after Chernobyl and Fukushima incidents and people voted twice against nuclear. Italy has some very competent companies in the nuclear field.

In the past I had very frequent migraines, I suspect caused by stress and irregular sleep (I worked for years in-call and making lot of night works). Migraines will usually come in the weekend and take sometimes more than 24 hours to end. T

In my team there is an ex professional cyclist from 80s. Sometimes he come in the Sunday group rides with one of his 80s bikes and he is able to overpass everybody. At the other side, I tried climbing the same hill at same power with my 201

Guess why only Basso and Ulrich get disqualified after the operacion Puerto and why Spain dominate in almost every sports for more than a decade.

I remember Fabio Aru saying that he was allowed to eat a pizza once in an year, at the end of the season. This is one of the reason why several modern cyclist had a mental breakdown like Tom Dumolin

In Italy, the most busy domestic route (Roma-Milano), was replaced by the high speed trains. Who would take a one hour flight if you can take a 3 hour train with no security controls, more space and arrivals and departures in the city cente

Disclaimer: I have worked in the past for one of the major HSM vendors, but things can be changed in the last years. To authenticate an application, you should generate a client certificate and share to the application, in order to create a

Public key encryption is computational expensive in embedded devices and microcontrollers. Using a simmetric key encryption with a pre shared key it's simpler and less complex.

What about having a better estimation of the speed of sound according to temperature and humidity? Do you think it can improve the accuracy ?

One of my unfinished side project is a physical time tracking. Nothing fancy, just few color buttons, an ESP32, an MQTT server and a unfinished frontend. Just need to find the time to finish it and release open source.

I am using the ones from SRICAM brand. The quality is not great, but they are cheap and they work well with ONVIF and motion.

As someone that I have worked for years with this kind of products in a couple of F500, I hate them with all of my heart. I really prefer the approach based on DNS and IP filtering, it's easier to manage and doesn't have all the p

Problem 6 has a similar resolution too: you have the circle of radius sqrt(3) and the rect a+b=n^2. Considering the fact that n is natural is easy to find the solutions: n=0 and n=1

It seems that there is a firmware doing SSB (I don't understand if it's real SSB or something emulated). Anyway, the radio chip of UV-K5 is able to manage distinct I-Q signal, so it just a matter of implementing SSB via software.

You can, but the problem is that the radio chip is not designed for the 27Mhz, then you will generate an huge amount of spurious that will pollute other bands and wasting lot of power. I advise don't do that, just to avoid to interfere
