I have had a sudden occurrence of interference on all my HF receivers /
transceivers recently. I cannot gain access to the remote location where they
are and am operating them remotely at the moment. At the site is my Trimble
Thunderbolt and it's been on permanently for several years with no apparent
issues. It feeds a divider by David Partridge. I am wondering if the TB could
be the source of the QRM in some way as it's bang on 10MHz. I no longer see WWV
but a very loud noise on all receivers on 10MHz, 20MHz and 30MHZ. If I zoom
right in I see what looks like FSK on the signal. The spurs are all over the
place and particularly bad, if they are indeed spurs of the 10MHz noise, around
21 MHz.
Would some Sherlock Holmes who is familiar with remote operating a Kiwi SDR
receiver have a look around and tell me if they think the TB could have gone
berserk in some way please? I can't think of any other 10Mhz source at the
location. Thanks and a belated happy and healthy New Year to all.
The Kiwi can be accessed at:
