7000dle Squeal noise while TXing Digital Modes
Posted: Thu Mar 05, 2020 8:08 pm
Recently while typing in a frequency an error was made and HPSDR mRX PS software set the frequency
to ~62.xxx MHz. A BIG resounding bunch of relays clicked inside the 7000 and ever since that event there is
a fairly loud high-pitched tone coming from inside the case during digital (FT8/WSPR) transmissions.
While in TX condition, I can back-off the tone-level driving the RF output level and the high-pitched tone goes
away.
Any ideas what is happening ? 73 Dick/w7wkr
