Just as an aside, you know how "they" say that you should not use the
"reply-to" field for mailing lists? "They" are wrong and stupid. That
is all.
Yeah, but the EraSynth is five times the cost. I'm writing all this
down, but I don't know how much use it will be. I don't even know what
a Morpheus is, and Web searches for that term are not enlightening.
You know, I'm not all that interested in general coverage 1 MHz to 6 GHz
stuff. I would be more interested in something that did 100 kHz to 200
MHz, because it suits what I want to do better and it seems like it
would be a whole lot cheaper.

Hi Jonathan,
Be aware that the 8 bit resolution of the DAC on the HackRF means that
you get quite a bit of quantization noise in the output. You can build
a filter bank to reduce those spurs but the end result is that the
HackRF's use as a signal generator is not as high as you might like. I
ended up getting one of the EraSynth ones off CrowdSupply when they
ran their first campaign and it has much lower phase noise and (in my
case) a wider range. I have used it as an LO with a mini-circuits
mixer to tune the entire amateur band for the HackRF (it also extended
the range of my HackRF to the 10Ghz bands as I can downconvert 10Ghz
to 1Ghz that the HackRF can handle nicely. While the Minicircuits
mixer is good to at least 10dBm I have not tried trancieving with it
yet. I also picked up a Morpheus (cheap at $125) which has the mixer
built in, but it doesn't have the range that the Erasynth does.

Please allow me to introduce myself. I'm Jonathan and I just
bought a
HackRF One with the intention of turning it into a software-defined
transceiver for amateur radio use. I figure that a power
amplifier and
T/R switch can't be all that hard (yeah, I know, "famous last words")
and I'm a computer programmer at my day job so the software part
is at
least do-able. The upshot is that I'm hoping that for a little
bit (or
a lot) of sweat equity, I can get an HF transceiver that is
similar to
commercial transceivers for a fraction of the cost. That's the plan,
anyway. I'm certain it'll be educational.
By looking over the recent archives, I see that other people have
tried
to do similar things, which is good because it means that I don't
have
to start from complete scratch.
For a long time, I been using one of those TV dongles as a
software-defined receiver to receive FM broadcast, 2m FM, and some 2m
and 70cm SSB/CW signals from satellites, so I don't have to climb
(much
of) a learning curve to work with GRC.
So far, I've plugged my HackRF One in to my Linux laptop and have
listened to some FM radio, and it seems to work.
At some point, I'm probably going to get another one so I can use
it as
a signal generator. Lots of useful things you can do with a signal
generator.
Anyway, that's me. If I have any questions about how to proceed,
I'll
let you know.
