Non-radar transponder codes

If you're out of radar coverage, why does anybody care what you squawk?

You'll have to ask ICAO that question. It's their rule.

What should I squawk? The same question applies to coming into a
radar-controlled environment from a non-radar environment like
approaching San Juan from Bermuda. Again, what should I squawk prior
to receiving a transponder code from San Juan? I was thinking that
the answer would be 1200 but the AIM says that 1200 is for VFR traffic
in the United States. Should you know the answer, I would also like
to know from where I can find the answer.

In a non-radar environment over international waters, 2000 is the default squawk
for IFR traffic. I don't know if it extends to VFR as well. Generally, though,
the ATC controller who provides flight following should tell you what to squawk
when radar service is terminated. If he says "Squawk VFR," then squawk 1200.
If he doesn't give you a code, ask.

Back in the 70s when I flew VFR over Puerto Rico and the USVI, we squawked 1200
when we had no other assigned squawk.

If you're approaching Sweden, maybe 7000

Also, look at the International Flight Information Manual at
http://www2.faa.gov/ats/aat/ifim/index.htm. At
http://www2.faa.gov/ats/aat/ifim/ifim0110.htm, at the bottom, they reference
ICAO Document 7030-Flight Rules, Flight Plans, ATC Clearances, Transponder
Operation, Communications and Reporting Procedures. You might have to buy it to
read it, though ($55 at http://www.ariane-info.com/icao-e.htm).

If he doesn't give you a code, you still squawk 1200.

Same today. In the seventies, VFR traffic at and above 10,000 MSL squawked
1400.

The international rules (besides specifying the usual codes for emergency,
radio failure and unlawful interference) say you should squawk:

1) whatever ATC instructs you to squawk or failing that

2) whatever "regional air navigation agreements" prescribe or failing that

3) 2000

Virtually every state except the USA has an Aeronautical Information
Publication (AIP) in which, amongst many other useful pieces of info, the
procedures which come under the heading of "regional air navigation
agreements" are set out. AIPs have a standard format set out by ICAO, and
the Radar Services and Procedures are in section ENR 1.6. It might be worth
checking the AIPs of the states you intend to visit. Your Aeronautical
Information Service (AIS) should keep a library of foreign AIPs. Of course
since the US has a one-of-a-kind system, your AIS may do it differently but
http://www1.faa.gov/ats/ata/ata100/index.html
may be able to help.

Most likely, as Steven says, you'll get a discrete squawk even if some of
the route is non-radar.

FWIW, in many parts of the world including most of Europe, the conspicuity
squawk (what you squawk, VFR or IFR, if you're not assigned anything else)
is 7000.

Hey Julian, do you like the CNX-80?

It came from your discussions of wanting a VNAV.
