Amateur Ham Radio Shortwave (LF, MF, HF, VHF, UHF, SHF) Communications + Space Weather
WTWW Air Check, 2021 November 28 @ 03:25 UTC
Reception of WTWW here in Ohio was marginal, but worse, the audio feed into the transmitter appears to be having intermittent cuts. The audio drops often, intermittently, during this short air check.
The international shortwave broadcasting station, WTWW, was broadcasting on the HF frequency of 5085 KHz, from their transmitting location which is south of my receiving station.
My station consists of an SDRPlay RSPdx radio receiver, hooked up to a 220-foot doublet antenna.

Does Your First HF Antenna Need to be Perfect? Just Get On the Air!
It might not take as much antenna as you may think would be necessary to make two-way contacts on shortwave radio (as an amateur radio operator putting an HF transceiver on the air). However, often, makeshift antennae are effective enough to be viable. Just look at all the contacts many amateur radio operators make with their low-power (QRP) rigs (transceivers) using short, helically-wound, mobile antenna sticks.
If they can work magic with such inefficient antenna setups, surely your effort at an antenna would pay off to some degree. Right?
Of course, I want to make a proper dipole out of this example antenna. But, while I wait for the rest of the parts I need to complete this antenna project (pulleys and a ladder, and maybe a potato launcher), I've put this makeshift antenna on the air, with it just high enough so that I can enjoy some time on the shortwave bands.
With this antenna, I've made successful two-way voice and Morse code contacts (QSOs) with stations in Europe and across North America. I am able to tune it on the 60-, 40-, 30-, 20-, 15-, 17-, 12-, and 10-Meter bands. Reverse beacon detection picks up my Morse-code CW signals, especially on 40 meters (the band on which it is tuned physically). Yes, this antenna, even at its current elevation, works. It works well enough that I can be patient on getting the rest of the supplies and hardware needed to erect this antenna high up in the trees.
The bottom line for you: just get something up in the air and start communicating. Improve things over time. You'll have much fun that way!
I'll be making videos during the builds and deployments of my antenna projects, as I go forward, so please subscribe and click the bell icon so that you will be alerted when I post new videos.
