Chevron East Bay Cities street map cover, 1964

Above: The cover of the 1964 East Bay Cities (Oakland, Berkeley, and so on) street map, published by the H.M. Goushá Company for Standard Oil of California, now Chevron. Chevron maps of the early 1960s featured color drawings of scenes from the area that the map depicted.

What's at this site?

This site features photos and other articles about interests of mine that I have shared over the years. See the Features listing on the right side of this page for links to different parts of the site.

Radios: In 2014, I gathered together articles that I had written about my collection of radios on various blogging sites, and put them here. A much earlier version of this site in the mid and late 1990s attempted to keep track of the comings and going of radio-station formats in Missouri, Kansas, and Illinois. When I moved to California, I discontinued that part of the site.

Roads: I was once a frequent participant on the Usenet newsgroup misc.transport.roads where, in the late 1990s, roadgeeks or roadfans would publish sites for the states where they lived. Remember that there wasn't Facebook or even blogging back then. Even though I didn't live in Missouri in 1997, I spent a lot of time there, motivating me to publish a site about Missouri roads. When I moved to California in 1999, I added photos of California road signs and sites. Subsequently, I added similar sites featuring New Mexico and featuring US highways in other states. Road maps are also a big interest of mine, especially historic maps of Missouri and California.

More: Aside from the list below, I have an interest in telephones and phone directories from the 1950s through the 1980s. I am also a road cyclist, but I don't have any related photos here. I'm really not a very fast or strong cyclist, but I can climb hills!

Where did the name come from?

The Cosmos-Monitor was the name of one of two daily newspapers in St. Charles, Missouri. It ceased publication in 1959. The other daily newspaper in St. Charles, the Banner-News, stopped publishing on May 31, 1978. Even though St. Charles and St. Charles County were rapidly-growing suburbs of St. Louis, evidently the Banner-News wasn't able to compete with the big city newspapers from St. Louis. After all, St. Louis County was just across the Missouri River.

Updates

All dates shown are based on the Mountain time zone in the United States (Note that I was in the Pacific time zone before 2024).

March 25, 2025: Added review of the Lijiani RD239 AM/FM/VHF/shortwave/weather-band radio with media player/recorder and flashlight!. Also updated the head-to-head performance comparisons to include an evaluation of the Lijiani RD239. Also updated the review of the Sangean DT-160 headphone radio.

Sharp-eyed readers and font fanatics will note that the Merriweather font used at this site changed recently. The spacing between letters is narrower and, unfortunately, text figures ("old style" numbers) have been replaced with lining figures. While I have plans to rearchitect this site, if I can ever get myself to start on those plans, I didn't expect to have to change fonts. I intend to investigate further. I chose Merriweather for the site because it provided old-style figures by default. I would like to restore them if possible.

March 4, 2025: Marks the 27th anniversary of this site.

March 1, 2025: Added some more material about area code changes in central Missouri in 1971, something that was rare at the time.

February 25, 2025: Small update, to fix an error in the spreadsheets used for comparing FM reception among radios. I incorrectly identified a translator for KTLF as the main station in Colorado Springs, rather than the translator that's based on Lookout Mountain west of Denver. No other changes, but a new review is coming soon.

January 22, 2025: Extensively updated the Tecsun PL-310ET and Tecsun PL-380 reviews, which had last been updated ten years ago. I've added new, improved photos of these radios, too!

January 15, 2025: Finally wrote an in-depth evaluation of the Qodosen DX-286's AM bandwidth filters and the surprising conclusions that I reached about them.

January 4, 2025: Find out how much radio you get for $20 by reading the SEMIER SM-817 radio/media player review.

December 28, 2024: Enhanced the head-to-head performance comparisons to compare the FM performance of the NAD 4300 AM/FM component tuner from 1989 with the two top-performing DSP-based radios of today, the Qodosen DX-286 and the Tecsun PL-320. In the process, I also extensively revised my 13+-year old review of the NAD 4300 AM/FM tuner.

December 23, 2024: Added a review of the XHDATA D-109WB AM/FM/shortwave/weather band radio and media player. Updated head-to-head performance comparisons to include an evaluation of the D-109WB's performance. Made a minor update to the Qodosen DX-286 review to reference those additional performance comparisons.

Life happens, and plans to do something different with this site had to be postponed to 2025. I'm still looking for an easier way of managing this site. I need to fix some things and will probably reduce the portions of the site devoted to roads and road signs, but that will take time. There are also many other things I want to do. I'm retired but have never been busier!
