If you're not getting spots and you think your setup is good ... it won't hurt to verify your TX QRG.

Lately, I've been noticing some WSPRs outside of the software's band pass (screen capture attached).

2016.11/26

it seems my other laptop has issues.

i swapped out one laptop (w/ OS X) for another laptop (old Windows Vista). all other items in the chain are the same, cables, interface, radios, antenna. sending out 30dBm on the ft-817.

Tokushima (some 500km away) is hearing me and reporting me at different frequencies w/ different SNR. at first i thought there was a bug w/ the 1.7-rc2 release i'm using but the same issue occurs with the official 1.6 (r6263) release. my ft-817 is showing 0 bars of alc.

Has been QRT for several months, just got lazy and overworked.

Finished moving to a new apartment! I have unpacked my HV-5S, FT-817 and SCU-17. I was disappointed after checking my setup last night and this morning. S8 noise on the bands supported by the HV-5S (40mb, 15mb, 6mb). Sheesh. Noise was tolerable in my previous appartment.

Antenna is indoor (attached to a tripod) since now I have no veranda. :-( Apartment is made of wood so indoor made sense to me.

I've got old JRC AC line noise suppressors on the outlets that I use.

So I've let the FT-817 run Tx for a day. The last Rx I got was 0048Z with a local station (JH1HRJ) after that the band seemed dead. I get VK4TVL around 0900Z but on this day I was not able to hear him/her.

The attached file shows the waterfall I saw when I checked the laptop running WSPR-X. There is very pronounced "banding". On "normal" days everything will just be covered with noise (i.e. the bands aren't perceivable).
