# How Many Drake 2-Bs Were Ever Made? Counting Boatanchors with the German Tank Problem It started, as these things do, with Bill (N2CQR) thinking out loud. On an episode of the *SolderSmoke* podcast he wondered how many Drake 2-B receivers the R.L. Drake Company had ever actuall
Yet another Greensleeves numbers-station transmission, decoded and analyzed.
A long late-September transmission from the fake Greensleeves numbers station.
A new fake numbers station emerges, reading oddly high-pitched numbers between 0 and 25.
A pencil-and-paper observation about the asymmetry of the borrowing algorithm.
At the start of every UTC minute, WWV and WWVH each transmit an 800 ms pulse on 15 MHz — often both audible at once. By stacking those pulses and fitting a smooth envelope model, we can read off their relative delay and watch WWVH fade while WWV stays steady.
A strange shortwave signal spotted by Ormu on the HF Underground Discord.
Some excellent basidiomycete fungus nearby today. This is the false Turkey tail: Stereum ostrea.
Parasola plicatilis
This one just came up in a sandy and rocky part of the yard that is complexly neglected. That seems to make it extra special.
Another hazy day with smoke from the Canadian wild fires. I’ve noticed this before, but shadows on a day like this are subtly interesting. To me they seem to have a hint of blue in them (see below) and for that matter the lite areas seem more red. Is this an optical illusion or t
Probably Panaeolus foenisecii or Panaeolus cinctulus.
Captured this last night. From left to right we have Mars, (tree), Venus and then the Moon. I don’t claim this is a great photo, just a cool conjunction. Captured on the (northern) Summer Solstice as well.
Most likely Coprinopsis atramentaria or the common ink cap
Not ‘the Fall’, just Fall – as in Autumn.
Mushroom season is well under way and this weekend in the Middlesex Fells I came across the largest patch of ‘Chicken of the Woods’ mushroom (Laetiporus sulphureus). See below: This lovely mushroom is apparently edible but I didn’t take any to try. Regretting that now. It should
I know I’ve been coming thick and fast with the mushroom updates but this weekend I solved a mystery that has been bothering me for a while. There seem to be two major, large, polypore mushrooms that I see attached to tree trunks in my area – the first was identified as the Birth
Wild mushroom literature is obsessed with a few types of mushroom species – usually for their flavour or medicinal value. When it comes to medicinal, none seems to be more prized than the Turkey Tail Mushroom (Trametes versicolor). This polypore mushroom (think pores, not gills,
We recently had some warm weather often extremely frigid conditions between Christmas 2017 and the first week and a half of 2018. Well, it warmed up to about 13 °C / 55 °F on Saturday so I hit up the Middlesex Fells with the dog. Over Christmas I’ve been reading more and more abo
6950 kHz, just before 0100 UTC 2017/9/5 – heard from Florida.
I had a another nice walk in the Middlesex Fells this weekend – just a quick one really with the dog this time. We happened to stumble upon this nice cluster of mushrooms, however. If anyone knows what species they are, I’d love to know! I have never seen such a cool cluster of m
Today I went on a nice little walk in the woods, just me and dog – like I do most weekends. Our favourite haunt is the Middlesex Fells, situated in the northern suburbs area of Boston. We’ve been going for about a year, so I have seen all seasons in the park/forest and know most
Following on from my last post, I’ve been trying to read the voltage values that are generated from the random number generator I put together. I was initially using an arduino unit so I could control the voltage output down to below 1 volt. Ultimately I want to read the values w
Intro: The notion of randomness has consistently intrigued me, so I have always wanted to build a random number generator and play with it. Just how easy is it to generate truly random numbers as opposed to pseudo-random numbers? First of all, pseudo-random numbers are based on a
