Good catch. This is a consequence of how the extension code is now loaded only on demand when selected from the extension menu or via the ext= URL parameter. The same needs to occur from the denoiser/autonotch buttons in the audio tab.

Correct. The WSPR extension ignores the tuned frequency. That's why it has WSPR band menu -- to allow the standard WSPR frequencies to be selected. It never even occurred to me to support non-standard frequencies. Why would I go to that considerable trouble when virtually no one would do that? (aside from maybe the transverter scenario) I don't even know how wsprnet.org would handle an uploaded spot with an odd frequency. Probably just filter it out.

Metal above the base of a E-field probe antenna is not a good idea. Pieter-Tjerk de Boer, PA3FWM, creator of WebSDR, explains why in this excellent article: http://www.pa3fwm.nl/technotes/tn07.html

Short answer: The Kiwi GPS is not as good/sensitive as other commercial GPS devices you may have. You cannot place the antennas of both at an inside window and expect similar results. Why this is so is a complicated story. Before you decide your Kiwi GPS puck antenna is broken it really needs to be tested while outside with a clear, unobstructed view of the sky (and without any cable extensions). Or with a longer length antenna/amplifier/low-loss cable combination that delivers an appropriate signal level to the Kiwi GPS input.

What you observed while unscrewing the SMA connector is likely just the elevation of the noise floor causing spurious sat acquisitions. The Kiwi GPS acquisition threshold is set very low to try and compensate for the low system gain at the expense of more false acquisitions. You are not receiving legitimate sat signals until the numbered "subframe" blocks start turning colors. Whenever the acquisition SNR exceeds 16 an attempt is made to track the signal (real or not). At that point you'll see gain, watchdog, status and RSSI numbers as you mentioned until the watchdog goes off after there have been no valid subframes detected and the channel goes back to being idle.

As to why the Kiwi isn't as good as a commercial GPS I'll save that for another post.
