Broadcasters who aimed to join the Conerlad network had to upgrade their sets, in order to switch to one of the said frequencies, also adding capabilities to modulate the antenna power down to 5KW and to pulse it to zero. Aviation radio frequencies are found in the low frequency (LF), medium frequency (MF), high frequency (HF), and very high frequency (VHF) bands. Twenty meters is a good all around band but Ive talked very long distances on 40 and 80 meters at night, and the higher hf bands can be quite good under the proper atmospheric conditions.
