.......... my Kiwi SDR in Wrightwood, CA. http://ak7v.hopto.org:8073/

I forgot to ask for tech details on your SDR. Please share!

Jim

Sure! Itís here at my place in Wrightwood, CA at 6275í ASL and Iíve had it working for about a year, but just put it online for the world a few weeks ago. Itís a KiwiSDR with a home brew 5v linear power supply. Antenna is a W6LVP active loop on a speaker stand in my backyard, fed with about 25 feet of RG-6.

Relatively rural area, but houses are close together so there is some domestic RFI. I donít seem to hear much above 15MHz - not sure if thatís the antenna, recent propagation, and/or being tucked up against a mountain. At some point I will put some wire up in the trees and see how those compare. But it seems to work great for MW and pretty well for the lower HF bands.

I used to live on a few acres and had bigger wire antennas (plus a vertical I transmitted with) and used my Perseus to listen. This setup now isnít quite as good, but for the space I have, itís acceptable.

Thanks for your interest and enjoy the SDR!

DW's I-TMP reading hit 105 today and it didn't seem to stop it from working  ;D

The three digit PV numbers are puzzling!

I noticed listening last night that the last whoop before telemetry is now more of a long dit than the normal whoop.  Was that just an anomaly of yesterday?

I've noticed that the higher the I-TMP number is above 80 degrees the shorter the last whoop is before CW is sent

the signal is peaking at 25 - 30 dB above the noise here at home

Interesting how the O & I temps are close. They are usually 5 degrees apart. Maybe thermal lag from the I temp location? Wish I had temp numbers for the whole day......
