I guess there is nothing to learn by doing nothing...

of course, a REAL CONTESTERS mode would just be hardwired to send "5NN" and maybe their call - 20 KHz high - of course.

I think the software would be locked on QRP calling frequencies and 14300. Time between calls would also be hardcoded to 0.1 second. Minimum power 500 Watts.

Thanks guys. I'm still wondering if 160m is worth a try or not... Its ground wave penetration capabilities are interesting. I learned it was even used in speleology. It makes me wonder if a dipole laid on the ground could work... Other than that, I guess you'd have to use a kite antenna. Not so many prepping applications it seems. Not to mention that very few people use it.

What do you think? Try it? Don't bother?

Excellent. The Technician license is easy. You might want to check the General book, it might convince you to give it a shot as well...

Google or ebay the ME40+. Just might fit your needs.

Thanks Rick! Great to see this awesome transceiver from Dave Benson (SW40+) back on the scene!

Gil, It is not clear how the three pieces are held together to make a solid unit?

Hi, I used a plastic rod inside the copper tubing for the gaps.

Quote
Was the 6 M antenna too flimsy because of the splice or not related.

Both because of the splice, plastic rods and the tubing being too thin. A 16mm tube will allow me to use a thick wooden dowel instead of a thin plastic rod.

Why not just use a regular straight fitting?

Fitting for what?

I presume this antenna is directional? How much gain?

Yes, gain is around 5.8dbi.

I've found that CONTESTIA 4/250 has a very good resilience -vs- speed and bandwidth.

Thanks Ray, I remember you mentioned it before. I'll test it as well. What an awful name though :o

Gil, I had been looking for a 40 M antenna and ordered one yesterday. Based on your review. Do you get some kind of credit for that ?
Hi, no but it couldn't hurt to mention my channel. Maybe that could get me more stuff to test...

Hello. I never have... Wondering about its utility in a prepping context...

Have you tried the 160m band? What is your experience? What do you think about it?

There are much better modes for chat than FT8.
Those "chatless," time-dependent modes are useless for prepping.
FSQ or Olivia come to mind, much better. I should be testing them soon.

i think its a great idea. but would the ability to atleast monitor the air bands or marine bands be important? offering an ability to know if someone who may not be on hf could be close enough to see a visual signal or close enough to keep your eyes open to avoid being found if thats is needed.
Yes, that's what a "General coverage receiver" does. Air band would be difficult to do but no problem for marine HF.

they state to have an ssb and an amateur radio on board but lost comms by loosing their antenna...

If you have a tuner, anything made of metal and a tad long can become an antenna, but maybe they did not have the technical knowledge to rig something up, the same way they couldn't rig a sail with what they had...

Maybe it wasn't a lack of preparation after all, but a lack of education and creativity in the technical realm.
