Know-how: The Single Sideband Radio - SAIL Magazine Is single sideband radio still relevant in today’s Starlink world?

SSB radio enables long-distance communication without satellites or infrastructure, using HF bands to bounce signals off the ionosphere. A lifeline for sailors beyond VHF & cellular range

WSPR is a great tool to:
- Optimize your RX/TX
- Assess your HF Propagation
- Compare performance with other stations
- Compare performance of Antennas
- Compare RX performance of Radios/SDRs

Some of the tools I use on a daily basis

The DX peak for the high ham radio bands was likely in 2024. Autumn MUF will show #sc25 #hamradio #spacewx

Look at the progress of their projects.

They are moving to slow. Too much overhead

Yes we will start with one transmitter and one rx

I was reaching out to ARDC to check if this project would qualify for a Grant. Unfortunately, individuals don't get grants without fiscal sponsors. Furthermore, ARDC wants to have evidence of demand from potential future users. Too many roadblocks...

This is bloody brilliant. I've spent months optimizing my RX and it's finally a top-notch receiving station. Over 1000 WSPR reporters in the last 24 hours, which I rank 12th for unique spots and 33rd for distance. Not bad at all considering my suburban QTH, far from an RFI quiet location

Thanks to WSPR, we know the rf power and thanks to the intl. WSPR Beacon Project, we also know the Antenna gain. We can derive a model from that. Step by step

The prediction quality is expected to be as ~good as that of terrestrial weather... Far from an exact science.

FT8 is not a good fit, no pwr information. WSPR contains locators and has a central DB with an API currently holding more than 9 billion historic spots. Thank you

The WSPR DB holds more than 9 billion spots, worldwide coverage, that‘s a good data source to start with

I am taking a break from social media. I need a digital detox. I will continue to experiment and chase DX. 73 #hamradio

Then do it. Not my interest

Deepseek's answer #hamradio

Question for the experts. Is there a difference in inductance between a copper tube and a copper rod with the same diameter?

Difference between the Wellgood and the N4CY Amp - RX-888 HF Spectrum #hamradio #swl

Tasmania, Australia and Ecuador ! 👍

What call r u using?

I have found a way to reduce the loop inductance of a magnetic antenna by 20% (using the same 22mm copper tube). I discovered this 5 years ago out of curiosity and it improved the RX, but I didn't know why at the time. Now I do... I'll have to confirm it with another 24 h WSPR comparison.

That my new radio setup inspired of @hb9vqq.bsky.social work

i duplicate that setup for all band 144/222/432/902/1296/10G

that replace the need of the costly flex6700 and permit to monitor all VHF band instead of only 2

More than 7000 WSPR Spots past 24h where distance > 6000 km at HB9VQQ - RX is King #hamradio #WSPR

The RSR200 will be in series production starting in January 2025. The price target is just below 1000€ and includes 2x 16-bit ADC, 2x HF inputs 0-71 MHz, 1 VHF input 70-250 MHz, diversity reception, and 1 Gb/s SFP LAN interface. The 2 ADCs can be interconnected in parallel or serial order #hamradio
