I mentioned to John that he’ll hone his skills the more he captures these Radiofax transmissions. John just sent the following update:
Indeed you are correct.
Having more luck decoding the Boston service… remembered I have a Sony AN-LP1 external antenna and so I unpacked and unraveled it and plugged in to the D-808 … drop that noise floor and…
