I now own five models of C.Crane receivers and after FARMERIK published a comparison of Sony receivers he owned on the Ultralight DX list, I decided to compare my C.Cranes in a similar manner using the radio's stock AM antennas.
I parked each radio in the same spot on my radio desk and in turn tuned across the AM band counting the number of stations heard. I did this between 1550 and 1655 UTC (1050 to 1155 local time/EST). My location is in Wolcott, Connecticut (41° 37' 48" N, 72° 56' 43" W) at 912 feet ASL. Radio conditions were flat.
Here are the results:
CC Radio 2E Enhanced: 60
CC Skywave: 60
CC SW Pocket: 53
CC Radio SW: 50
CC Pocket: 45
The CC Skywave and CC Radio 2E heard the same 60 stations with two exceptions: the Skywave heard a station on 850 kHz that the 2E did not and the 2E heard a station on 920 kHz that the Skywave did not.
Comparing the Skywave and the 2E, their sensitivity is similar on the AM band in my opinion, but the Skywave is more selective. 1070 kHz is a problem area at my location because the 50 kW of WTIC on 1080 kHz blasts through here 24/7. Until I added the Skywave (and an Elecraft KX3) to my radio shack, I never heard anything but QRM from WTIC on 1070 kHz. With the Skywave, I’ve logged four stations on 1070.
On the other hand, the 2E sounds much better than the Skywave. Of course, size matters and you would expect the 2E to sound better than its pint-sized cousin. The 2E is the best sounding AM radio I have ever owned.
