It is a mess posting on 8kun. To make posts, anons having to go back out to catalog and post. It is seriously messing with ability to have a conversation with anons on a subject. Error messages like I’ve never seen. Came here for Sanity.

Just how far could Nellie Ohr communicate with her HAM radio? Think she had the same level of equipment that the average amateur has? Same training as the avrrage person? Extra training? When one hears about such things as using such a thing as a meteor shower as a reflective surface to bounce comms off of, makes you wonder if chemical spraying with variants of aluminum oxide might not help an agent in the field communicate when conditions were not adequate using “moonbounce” method.

Weak Signal -- (VHF-DX, Meteor Scatter, EME-Moonbounce)

Introduction

Communicating over great distances via VHF continues to fascinate many amateurs. EME (Earth-Moon-Earth) communication, also known as "moonbounce", meteor scatter, and VHF cw DX are some of the techniques used. In the case of EME and meteor scatter, the concept is simple: use the moon or the ionized trail of a meteor as a passive reflector for VHF and UHF signals. A simple but effective station is within the reach of most amateur experimenters. With the advent of very sensitive receiving preamplifiers and commercially available high-gain Yagi antennas, many VHF operators are enjoying successful weak signal contacts. With a total path length of about 500,000 miles, EME is the ultimate DX -- for the time being! Weak signal VHF work is discussed in a operational way at the Weak Signal Operating page.

Just posting this here for real anons who like to dig on stuff related to Q drops. Not you metaphysical faggots who really should find another board to post on.

Won’t allow a pic. Trying just text. Catalog page - no nav icons but QRB page had icons which allowed me to captcha but no pics. Trying text.

Site currently not responding when trying to respond to a poster. I typed your post# in manually.

 

Thanks Baker!

 

Wonky but lucky to be up all. Can’t find a QR (8kun) new thread in that catalog.

In QRB catalog onserved nav icons not populating, however tried the QRB thread and after.couple of refteshes got the nav icons to do captcha. In my first post the pic selection tab went to my pics but when selecting image did not get a blue check mark on inage to verify that correct image is srlected- went straight back to post page which caused me to doubt pic was selected.

Looked for conf on the ppst entry but was not seeing it. Am now seeing it on my second try. But no blue check conf when selecting image.

 

Thanks for everything you bakers are doing.

Yes. Not as pretty as Melania’s but I hope very BIG surprises behind each one!

 

In my mind I picture actual doors with Santa’s Helpers serving search warrants and bringing Christmas cheer.
