Why, Web? The DC receiver had a lot of short -comings, particularly with 
the needed frequency stability for modern QRSS use. A narrow IF filter 
(or audio in the case of the DC receiver) with sharp skirts is also a 
must. Save your pennies and buy an R-75 off Ebay.

The design of the transmitter is about 1000 times less critical compared 
to a good LF receiver and is simple (and fun) to construct. Then there's 
the antenna.... well, take it from me, there's one type that is 100 
times as easy to construct and maintain as the other popular type :)

    Think you meant the "Dave Curry" transceiver, which he discontinued 
selling [always at a loss by the way, it was the typical "labor of 
love"] as he began to start a family and got more responsible jobs.  I'm 
sure he'd agree with Bill's comments about it - it was intended more for 
good signal communications than anything else.  He has a new version in 
the works with a synthesized LO, but that won't overcome the sensitivity 
and selectivity problems.  He has no plans for selling the thing.  We 
get on 75 meters every Sunday morning to talk about LF stuff (and many 
other things) and Dave's current project is to get a final design for 
his 60 watt Part 5 transmitter.  Not sure if it will end up with PSK 
capability or not - we've discussed it a lot.

     The remark about the transmitter is sure true.  Building a good 
receiver is a lot of work, almost as much work to design and build one 
as to do a production design and rarely worth it!
