[160m] Re: Topband: Digi transmitter spur

[Jon Zaimes AA1K]

At 0645-0655z today (9/23) I am hearing the spurs on 1814 and 1832.4.

They are only S4-S5 or so on a fairly quiet band. I hear them on the 
205, 245 and 280-degree Beverages but they seem strongest on the 245.

The signals below 1800 are a bit stronger, with 1777 strongest at S6 to S7.

I'm not hearing the "minor spurs."

And nil hr on the SYZ signal.
