Al,
I cannot comment offhand about any low cost commercial signal signal
generator that would suit your requirements, but if you are prepared to
homebrew there are many low cost options. If you did
homebrew and if you needed to know the output level from the generator when
using it, you would need to measure RF voltage with good accuracy when
calibrating the generator feeding a 50 ohm load. Also I would suggest in
this case that you purchase rather than build a step attenuator capable of
introducing at least 60db of attenuation. It is possible to build a good
step attenuator, but you would require
good test equipment to check its performance, also its enclosure and its
internal shielding partitions have to be built in addition to the
'electronics'.
On the other hand if you only require a generator which can produce a stable
but tuneable unmodulated carrier in the 40 - 15m bands, and you are not
interested in the actual value of its output level (which could be adjusted
during use), a homebrewed generator can be very simple. Other than a
receiver with frequency readout test equipment is not essential, although
having a DMM is a good idea.
Please contact me off-list if you would like to discuss this further.

Good morning folks ! I am looking for a signal generator that outputs
signals across the frequencies of the 15-40 band, and does not cost an arm
and a leg. Need your advice, does such a creature exist?
Al
