Good story Edwin, I feel the same.
I have my way with documentation and manuals,
however good they may be, you need to familiarise with new techniques and systems.
AND .... a wire cutter, screwdriver and soldering iron...... :-)

Difficult is a relative term. Perhaps we should use the term "more

I have 1 SDR-1000 and it took me about an hour and a half before I was on
the air. On the other hand I have a Yaesu FT-847 and it took me about 5
minutes to get it on the air.

9 out of 10 times when I tell a fellow ham that I'm using an SDR-1000 the
first question is "how hard was it to set that thing up?" I always respond
that it was not plug and play but it takes more time to set up. One must
follow the instructions to the letter. When I opened the box that I received
from Flex there was a warning to read the instructions or the radio can self
destruct or somesuch. I'm not sure if that was a joke or not but I took it

I never knew what phantom power was until I read the primer on the types of
mikes. Plug my mike into the sound card? What does that mean? The radio has
a mike jack on the front. Shouldn't I plug it in there? Doing that can cause
ground loops? Then why is there a mike jack on the front panel?

The paragraph above needs to be read a few times before a non flex owner
could understand what is being discussed. Terms to review:
Serial connection method
Port (what port?)

You mean I have to start building my own cables? Can't I just by one from
I've never used a separate PTT in my life. The few radios that I have always
had a mike with a PTT. Now I have to start thinking about a PTT?

Now I have to order a signal generator and then build it? How much time will
that add before I can start enjoying this radio?

My comments above reflect what I would have asked if I wasn't familiar with
the radio. I think that some folks don't realize how radically different our
SDR-1000 is from a conventional radio. One needs to get into the mindset of
what this radio actually is before he can take the plunge and buy one with
When I first started reading the reflector archives I knew that I would have
to approach this radio from a different perspective. I placed my
expectations on an extremely low level and said I am going to keep this
radio no matter what happens (within reason of course). I read that it was a
work in progress so I did not expect everything to work perfectly. I based
my decision to purchase this radio mainly on the reviews on eham.net and was
astonished at the level of satisfaction from the users who posted reviews.
I also believe that the skill level of many who answer questions on this
reflector is beyond exceptional. Highly skilled users may find the radio
easy to set up. The average joe like myself might agree that the radio is
"more involved" to set up and others may interpret that as difficult.
If my Yaesu S meter locked up I would send it back. If the receiver on my
Yaesu lost sensitivity when I discharged static on the miccrophone I would
send it back. If I had all types of audio hums that I couldn't ger rid of, I
would send it back. If I transmitted a Spur on AM, I would send it back.
If my built in auto tuner displayed and SWR of 1.1 even if I attempted to
tune a paperclip, I would have sent it back. if the panadapter on my Icom
7800 ( I wish!!) displayed a DC hump I would send it back. With the
SDR-1000 I don't feel the same way.
I'm sure there are some of us who have been unable to solve their problems
with this radio but are patient because this is cutting edge technology and
know eventually it will be fixed or they will most likely fix it themselves.
My S meter froze about 3 times. I can live with that.
As I said before, difficult is a relative term. This radio will be difficult
for some to set up. And easy for others. It is definitely "more involved" to
set up than any radio I've owned before. However, the extra involvement is
worth it, in my view.
