Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

this is just a really extravagant heater, physics forbids antenna this small to have good radiation resistance. for your contrived below noise communications scheme, you need more bandwidth that is physically possible on hf, yet you choose antenna design that is even less wideband than regular dipole. 40m of wire is for 80m band, which is usable more often in this configuration, ignoring everything else

As for throughput: a channel that is 9 KHz wide is supposed to transfer 9.6 kbit / s

5500kbps in extremely favourable conditions is your peak attainable speed, bandwiths in normal radios are narrower

A reasonable detection avoidance technique might be broadcasting from a depressed location or an urban canyon with tall ground clutter

if you don't want anyone to hear you

launch your guerilla transmitter on a free flight balloon, and will have plentiful line of sight.

with what power source? better study for and get your license, start using radio and stop embarrassing yourself
