New from pryiom.org is rx.linkfanel.net, an alternative to sdr.hu/map that features color coded Kiwi status and a day/night map overlay.Thanks Pierre! -

lookup databases websites for NDBs and LW/MW bands.
Tonda,Yes, I was undecided about perhaps selecting the Europe or NA lists depending on the ITU region (admin configuration setting) of the Kiwi. I thought for the benefit of DXing it made sense to always select the worldwide list and let the user narrow the selection after that. You could say the same thing for my decision to select the DGPS, NAVTEX and NDB categories as the default.Once again, in the future this could be a per-user customization that you set once and it would apply to all Kiwis you visit. -

Worried about time?
[humor, sarcasm]Sure, but be careful. For some people this is a slippery slope into full-blown "time nuttery", e.g. Time-Nuts, LeapSecond.com. Believe me, I know. It starts with PPS-producing GPS modules. But then quickly escalates into buying a GPSDO and/or surplus rubidium OCXODO from that Ebay guy in China. All of a sudden you're building your own GPSDO. Then acquiring an old hp 5370A/B TI counter, or two, or three or ten. Perhaps even adding my CPU upgrade. Then you score your first cesium standard off Ebay. You might even get one with a semi-working beam tube. Pretty soon the Allen deviation/variation plots are flowing and three-corner hat comparisons being made. This list is maybe 2% of what's likely to happen.Now things really fall apart. You decide you need a hydrogen maser. So the sports car and/or summer home get sold to raise the cash required..Absolutely no cure, except to get distracted by something equally interesting/addictive. -
KiwiSDR Clock Lags?
One thing I could do I suppose is have the Kiwi server occasionally check for NTPd running and restart it if necessary.Something like that always sounds simple. But when it comes to implementation there are always funny edge cases to consider and the possibility I'll release a version that bricks everyone's Kiwi. I've been lucky about that so far.. -
How to set the DST?
In the v1.77 release the lat/lon for finding the timezone will be taken from a GPS solution if the lat/lon field has not been set on the sdr.hu tab of the admin page. If you look in the log tab there will be a bunch of messages beginning with "TIMEZONE" that describe what is going on including any errors in the process of converting lat/lon to timezone. -

Using BB Black wireless or BB Green wireless board
Yes, a WiFi dongle on the end of a USB cable with some type 77 and/or 43 toroid cores as a common mode choke is a great idea. Be sure to use a 5V power supply of at least 2A. The Beagle manual warns about the increased current requirements when using WiFi dongles.A long Ethernet cable shouldn't be a problem (the spec is 100m max). Just use toroids as above at the Beagle end. Because Ethernet uses differential signaling it isn't much of a problem except for the EMI from elsewhere that rides down the cable common mode. Be sure not to use shielded Ethernet cable as this may cause a big ground loop depending on your equipment grounding.
