#Multiband

Other key points :
• Neural predictors of risky choice can be triply dissociated from neural correlates of sensory input and motor output.
• Predictors generalize across samples, tasks, and analyses (a priori and post-hoc)
• Predictors also account for individual differences in risky choice within the lab, as well as debt beyond the lab.
• Findings robustly support a #BrainAsPredictor account of risky choice of gambles (if you don't blow out your signal in the middle of the brain with #multiband #FMRI acquisition, see Study 4)

Hoo boy (could check with #MID data?)… #multiband #FMRI

Are there any #Bitwig v4.0+ users out there who might want try out my #Drawmer1973 inspired #Multiband #Compressor preset? If interested please leave a comment. What’s a Drawmer 1973? This - drawmer.com/products/70s_serie

Warning: #Multiband acquisition can decrease #FMRI signal to noise ratio due to smaller voxels, shorter echo time, and nonlinear noise induction (thanks to Matt Wall for the mention):

#Multiband acquisition increases #FMRI signal dropout (from Wall, 2023)

After some experimental review at 30ish watts, the 10 meter element on the #hexbeam needs some inspection, but the other bands seem to behave. On the #trapped #multiband #fan #dipole, however, receive is fine but my #transmatch just can’t cope on transmit. I hope that’s a #feedline problem and not an #antenna problem. Either way, I must ascend to the roof to see what’s what. Perhaps two weekends from now; next weekend is booked for #portable #operating already 😁

A 3-6-9 Antenna Pulls in the Signals

Every time we see a dispatch from [Mr. Carlson], we imagine it is being beamed from his orbital station packed full of vintage radio gear. We are certain the reality is more terrestrial, but if we were going to build an orbiting lab, it might look like [Carlson's] shack. In his latest communique, he shares his progress working on a high-performance 3-6-9 receiving antenna design and you can see it in the video below.

Although the antenna isn't done, it is already working and looks impressive. There's a lot of wire, so this probably isn't a condo-friendly solution. The name of the antenna derives from the three wires, one tuned for 3 MHz, one for 6 MHz, and the other for 9 MHz.

The mechanical construction is impressive, with springs and pulleys. The wire used is actually MIG welding wire which is cheap and durable. Supposedly, the antenna has already performed well with an average receiver, but we didn't get to hear it ourselves. Maybe in the next video.

If you are looking for more antenna theory, we got you. If height's got you down, try rising to the occasion.
