2M FM Simplex
« on: March 27, 2022, 1114 UTC »
Turned on my VHF rig while tuning HF bands. 2M has great conditions this morning. Running 20 watts into a small vertical @20' I was able to work a station 38 miles West of me (146.520 FM) at 11:13. I normally have a very tough time working to my West. It's a bit of a dead zone for some reason. There's a station running 50 watts into a vertical at 110' working just about the whole state. He's got a pretty great set-up for sure.
Yaesu FT-950, 135' OCF dipole @ 28', SignaLink interface, Vibroplex Square Racer paddle and a Grundig G3 when portable.

Just glanced at the estimated MUF map. Consider giving 6m a try today. I suspect you might find opportunities for TEP DX into South America.

Is there any way that you could get your VHF VERT above the tree, foliage, level? Being in the land of FL, I would believe that 20W on 2M could talk 38 miles daily. And, if you happen to have a 2M beam, you could bounce off of a tall BLDG and see how far you could get out. A friend of mine and I did that with 222MHz national Simplex FREQ 223.500MHz FM. He was over 20 miles away on a IC-3AT HT, (MAX'es-Out at 1.5W.), and I was on my base with a home-brew 1/4-Wave GND-plane. I talked him into downtown Corning, NY, mobile, then lost him. Minutes later, I heard him call me. He was standing 10ft from the front wall of a Wagmans Supermarket and found a sweet-spot to work me on his HT! If he moved a couple of feet, I couldn't hear him. It was a neat test. We also did that bouncing signals off of hills too. BTW, that trick works well on 440MHz, 446.000MHz simplex FM. Passing thoughts.
Proving and convincing that someone is correct could be seen as a notable achievement. However, proving, and trying to convince, that someone is wrong can bastardize you for life.

Oh well. I noted a rather high MUF in SA earlier today, though yeah, our MUF was like 15MHz lower so 6m was a somewhat long shot.

Sad

The furthest I ever worked simplex 2 meters fm was from Pennsylvania to FloriDA with a home made antenna up about 30' off the ground.

The most important part is to buy the very best coaX AND THE VERY BEST ANTENNA AND PUT IT UP ON A TOWER AT LEast 30 or 40 feet off the ground and buy a good radio - 50 watts - not one of those cheap POS chinese radios you see that are copycaTS of a good radio you should have bought in the first place.
