New SDR receiver kit available

From Hans G0UPL:

"At last, the receiver module is now in the QRP Labs shop! This receiver kit is a high performance single-band receiver module, with I-Q output for SDR programs or WSPR (for example).

One year from today...

...the track of a total solar eclipse will cross the United States from Oregon to South Carolina.

Many populated locations along the path will experience from 1min 30sec to 2min 40sec of late morning or early afternoon darkness with visible stars.

According to this very descriptive website, hotels will be booked far in advance for this rare event. The last one occurred here in the year 1257; the next one is in 2316.

Borah Peak - Idaho's highest - will be in the path of totality. What a great time for a SOTA activation.

First look: Icom IC-7610

It's nice to see a major manufacturer migrate to SDR architecture. We have Flex of course, but for one of the Big Three to jump into the SDR field - I believe it is representative of things to come.

2001 QRP Rendezvous - why didn't it catch on?

Guy Hamblen N7UN inadvertently jogged my memory with his SOTA audio interview. Though I've never had much interest in activating a SOTA myself, Guy's talk about groups of QRPers heading outdoors for some on-the-air wilderness activity reminded me of the "2001 QRP Rendezvous" sponsored by the Adventure Radio Society.

"Heavy Water War" and the Kon-Tiki wireless op

Science combined with war history is a rare genre for a TV mini-series but Netflix is currently streaming one that appeals to my interest in both categories. If you don't mind subtitles, you may find the series both educational and entertaining.

Flex going to Bouvet

It's surprising to see a major DXpedition use anything other than Elecraft gear, but doubly surprising is that the upcoming DXpedition to Bouvet Island will be using eight Flex 6500 SDR transceivers.

A weather-resistant QRP rig from the last century

80m Bobcat (3500-4000 kHz, CW only)
As Elecraft and KD1JV continue to develop smaller and more capable QRP rigs for outdoor use perhaps the next step in their development lies not size reduction but in environmental protection.

This year's NPOTA event has put people in the field with their radio gear - perhaps many of them wouldn't have considered it otherwise. Smart phone manufacturers are now giving increased attention to "weather-resistancy" long before HF ham radio manufacturers follow suit?
