Great news! 7335 always was a crap frequency for them.
Peace!
How do you figure that?
If you lived on the west coast, you would not say that. Other than a couple of years around sunspot peaks, 40M is a crap E-W propagation band.
Peace!
Then, can I make a hint of a suggestion and recommend that the receiving party switch to another frequency?
A 'bad' or crap freq for one person might actually be a good frequency for another ... a better way to have expressed that might have been 'always had crap reception on that band given propagation and my location'. These are, after all, utility (time and frequency reference stations) stations; one should suffice for another JJY, WWV, WWVB, CHU etc. for the purposes they were designed.
Anyway, just sayin ...
(In the spirit of full disclosure - for both work and ham-hobby, I have zero-beat/made use of these time-base/frequency references stations on a number of pieces of gear over the years including counters, signal generators and now the higher-accuracy synthesized gen coverage and ham rigs over the years using WWV; WWVB, the VLF source, used to be *the* standard phased tracked by labs to keep the central 10 MHz frequency source accurate before GPS ... you probably know all this! Sorry for the history lesson! Full disclosure: been in comms, incl. engineering and even ops aspects for awhile in the yrs since school!)
