About

This site is used for my personal DX loggings and related radio geekery.  Most of my interest is on the medium wave (AM) band however there will be occasional updates from other bands.

I launched my first DX site in 1998 as ‘eudx.net’.  For the next three years I updated loggings on that site on a fairly regular basis.  Around 2001 my DX activity tapered off.  I relaunched that site in December 2007 updating very rarely until 2011.  The loggings from each launch have been included in this new site’s master freq list.

Glossary/FAQ 

• DX – stands for distance listening.  It is the act of receiving groundwave and skywave broadcasts from far outside the typical range.
• Skywave – broadcast signals that are reflected off of the ionosphere back down to earth a great distance away from where they originate from.  This phenomena occurs most noticeably after sundown because the lack of UV light and Xrays from the sun decreases the number of layers making up the ionosphere.  There is a good explanation on this site.
• Groundwave – broadcast signals that travel horizontally across the land from the transmitter to your radio.  This is what is typical in the daylight hours.
• SW – shortwave broadcast band
• MW – mediumwave or AM radio broadcast band
• LW – longwave broadcast band – used for broadcasts in Europe, Asia and Africa.  In North America and South America it is used for navigational beacons and other specialty applications.
• Ham Radio – aka Amateur radio (wiki)

Equipment

Nothing fancy, just some portables.

• C Crane CCRadio 1 – AM/FM/WX/TV – 1st Model, first restock after initial sellout.  Distance AM reception is amazing.  AM selectivity is the greatest out of all my radios.
• C Crane CCRadio 2 – I returned this!  Selectivity was noticeably worse than CCradio 1.
• Sangean ATS-505 – AM/LW/SW/FM – very good receiver.  Features SSB mode and 1khz increment tuning.  The one downside is the limited LW tuning 153-279kHz.
• Tecsun PL-606 – AM/LW/SW/FM – although selectivity is amazing (especially on FM), its size is prohibitive because the LW/MW antenna is small.  LW tuning is full 153-512kHz however 513-519kHz is omitted from either band modes.  Three option bandwidth size selector.
• Tecsun PL-660 – AM/LW/SW/FM/AIR – very good selectivity.  Radio is a decent size so the LW/MW antenna is better than the PL-606.  Great features like separate USB and LSB modes (for LW & SW), three option antenna gain selection and a two option bandwidth size selector.  LW tuning starts low at 100kHz and all frequencies are covered up to 29999kHz.  Airband (airplane to airport tower communcation frequencies) has very good step tune-ability.  Downside is that FM tuning is not as tight and isolating as the smaller PL-606.
• Sangean PR-D5 – AM/FM/RDS – very solid mwdx radio.  It doesn’t quite replace my CCradio but it comes close.  My only wish is that  it had 1khz tuning increment option.  FM tuning and selectivity is better than average.  It does have RDS which is an added bonus.
• Sony ICF-SW7600GR – AM/LW/SW/FM – the newest addition to my collection (10/2014).  The LW/MW/SW tuning is continuous from 150-29999 kHz.  It also features SSB modes and a variable attenuator.  I think the FM tuning in a full broadcast market is terrible even with the attenuator.  However that wasn’t a deal breaker for me because I don’t use this radio for FM.  The internal antenna definitely out performs the Tecson PL-660 on LW.

All are table top portables using an internal ferrite and telescoping whip.  I have not used any added loop antennas for LW/MW.

Location

My home location is eastern Massachusetts in the United States.  I am about 10 miles west of the ocean proper, 8 miles west of downtown Boston and Boston Harbor.  My time zone is UTC -5.
