Many thanks to\u00a0SWLing Post<\/em>\u00a0contributor,\u00a0Rolf Snijder, who writes:<\/p>\n

I have added an external antenna capability for mediumwave on the XHData D-808.<\/p>\n

Simply add a 27 pF capacitor on the backside of the PCB on C10 to the the ferrite antenna.<\/p>\n

\"\"<\/a>\"\"<\/a><\/p>\n

The mod causes no loss on FM or shortwave!<\/p>\n

I also replaced the Ferrite antenna with a bigger one so I now have more performance on MW!<\/p>\n

\"\"<\/a><\/p>\n

Longwave is not good in my radio, even with an external antenna, it is not performing well.<\/p><\/blockquote>\n

Thanks once again, Rolf! I must assume that the Digitech AR-1780<\/a> could be modified in the same way as the radios appear to be near identical. Perhaps someone can verify this at some point!<\/p>\n","protected":false},"excerpt":{"rendered":"
