Topband: SDR radio for 160

[Pete Smith]

Readers should be aware of some complications -- the amqrp.org link is 
well out of date - like about 4 years.  For a time, 
www.softrockradio.org was the place to go for information on the 
softrock series of kits, but that site is now a mishmash of parts 
offered for sale, with no particular link to the kitter, KB9YIG.  There 
is a site, www.kb9yig.org, that purports to have prices and availability 
information, but it appears to have been static for 6 months or so, with 
almost no kits listed as available.  The softrock40 group on 
groups.yahoo.com still appears to be active, and has a lot of 
information in its files section, but nothing on availability of kits 
since last May, and nothing by or about kb9yig since then either.

I always found Tony, KB9YIG, to be the soul of conscientious service and 
reliability - it would be a shame if this effort is going offline.  I 
hope Tony is OK, but have no clue.

73, Pete N4ZR
