Commentary about Les Paul into music around 0012z. Peaking S7 on the 31' vertical. Occasional fades and static crashes, as in the usual tropical HF noise for Florida summertime, though still an easy copy with good modulation. SINPO 45444.

Thanks for the broadcast!

On a related tangent, FreeDV might be of interest for spoken-word and similar low-complexity content.

~S5 but well underneath rather powerful UTEs here.

2240z - Intermittent UTEs, but now peaking up to S9 with a much better copy and clear modulation.
2241z - SSTV

"Patrick Jr." playing hip-hop, rap, and rock. Commentary about transmitter repairs and a new antenna needing trimmed.

S9+10 at SINPO 55455 via the 148' loop-on-ground antenna and preamp. Strong modulation.

2215z - Multiple SSTV if anyone has decodes.
2230z - Said to be transmitting from Ireland.
2235z - Off air.

Add a connector and build a basic wire j-pole. Lots of j-pole plans and calcs on the net. Opt for a BNC if you want to retain handheld use of a rubber duck or similar.

You can use 450-ohm twinlead for the antenna, 50-ohm coax for the feedline, and air-wound coax for a simple choke. Get a slingshot or fishing pole, and raise the antenna via a tree.

Do the same for two units, and you might successfully complete line of sight comms up to several miles assuming enough height and no significant obstructions, even with just milliwatts of radiated power.

I recommend a wire j-pole for being lightweight, easy to build, and readily deployable with a single support. It is also vertically polarized (unless hung sideways ;), which is a plus for talking with other typical handheld users in your expected comms group.

BTW, 49MHz also can do over the horizon even at QRP just like the nearby 6m amateur band, but think more along the lines of using multi-element yagis at decent height on each end of the connection.

Rock music peaking S9+ and SINPO 45344 at 0309z via the 148' loop-on-ground and preamp. ID a minute or two later.

Considerable static crashing, but that is generally expected for the tropic bands at my location this time of year. Otherwise, a decent to good copy with clear modulation.

Thanks for the broadcast.... and shoutout! :)

Chillout, downtempo, jazz, etc. music peaking S7+ and SINPO 35434 at 0032z via the 148' loop-on-ground with preamp. Some significant fades but a decent copy. Clear modulation, too.

0033z - Audio breakups noted.
0035z - Audio restored. :)

Thanks for the broadcast!

Music peaking almost S9 at 0022z and SINPO 43444 via the 148' loop-on-ground with preamp. Some intermittent interference.

Thanks for the broadcast!

Heard it at the time while rolling a receiver VFO. It was modulated loud and wide enough that I actually caught it around 6928.5 in LSB mode.

Likely related, as same or similar siren heard here a few minutes ago:

I hear the modulation and an occasional lyric, but the signal is largely in the noise floor here.

Nonetheless, thanks for the broadcast!

Techno bass. S6 and SINPO 35444 via the 148' loop-on-ground and preamp. Strong modulation. Some fades and static crashes, but otherwise an armchair copy.

SSTV at 0113z if anyone has a decoding to post.

Thanks for the broadcast!

Averaging around S2 and SINPO 25333 via the 148' loop-on-ground and preamp. Static crashes and some fades, though good modulation and a decent copy considering current conditions here.

Thanks for the broadcast!

Jazz music. Under S1 and SINPO 14333 via the 148' loop-on-ground without preamp. Intermittent UTE and fades, but good modulation and a surprisingly decent copy. I think an ID at ~0019z, but I missed it.

Thanks for the broadcast!

Commentary, skit, crank call, ranting, or similar at 2208z. Slightly above the noise floor, so a tough copy.

Modulation fading in and out of the noise level at 2145z. Intermittent UTE currently on frequency, too. It is a rough copy here, but I know it is there.

Thanks for the broadcast!
