Default Lowe HF-235 ???

Has anyone on the list used this receiver and if so I'd like opinions as to
how it compares to other Lowes and other high end receivers. What's betterin
this price range, and how much?
tnx

had one here awhile back. OK, but a bit over priced. i brought a new
235 mil set up home from europe about 3 years ago. if i remember,
it cost me a little over $300 USD. i don't know what that comes
to in euros. they didn't sell too well. the hot one is the 150
and 150E. i tried to sell the 235 on ebay and could even get a
buy it now of $300 i paid for it. i had to pull a trade on Grove
for something else. the 235 was an odd ball. they were made for the
military, but wouldn't sell. too much over load. i only keep it
for a few months, dumped it as quick as i could. i see a lot of
them used in the SW shops all over europe and the UK. if you
have to have one for a collection, check the web. most shops over
there import to the US. i saw one on ebay, jan this year. had a buy it
now of just under $900. didn't get a single bid. so, i think that
says it all. if you want a lowe, go for the 150, great little rig.
put a post up for Lucky. he just got a 150. ask him how he likes his.

I also have a 150 and it's great fun. It's very 'minimalist' in design,
offering fewer bells and whistles--and better overall performance--than
many receivers.

Build quality is superb.

Sound quality is superb.

The tuning knob is to die for. Tuning around in SSB has a distinctly
'analogue' feel, in large part because of 8 hz tuning increments.

I'm told that the 150 has a relatively weak front end, but that's
easily (and inexpensively) fixed with a BCB rejection filter or
preselector. Using my 150 with a Wellbrook 330S antenna, I find that I
need neither of these add-ons.

Wasn't the HF-235 little more than a 19" version of the HF-225?
Whatever, at least according to Sherwood Engineering measurements even
the HF-150 provides better strong signal handling than the HF-235, at
little worse ultimate rejection and phase noise. Looks like this is more
of a middle class receiver rather than high end, though it'll certainly
have good audio.

I also have a Lowe HF-150. A good receiver. Connecting an RF generator
directly overloads the '150 at 120mV when the preamp is switched off, which
is very good when you consider that the Icom R75 overloads at 100mV, also a
very good figure. Note that I am talking about the point where the AGC "runs
out of steam" and the I.F. strip is driven into clipping.
The minimum discernable signal on the HF-150 is 0.08uV on all ranges when
the preamp is switched off, improving to .04uV when the preamp is engaged.
I just got through adding an LED backlight to my '150............a nice ruby
red color. Doing this mod is not for the faint of heart since it involves
unplugging the LCD from its socket (a very fragile component) and very
carefully peeling the reflective foil from the back of the LCD itself. After
this is done, you need to remove the glue from the rear of the display with
something such as alcohol. I used a product called Goo-Gone, but I am not
sure how this affects the soft front surface of the LCD. I ended up with
some micro scratches on the front of my display and ended up polishing it
with 0.7 micron polish.
This is just one of those "rites of passage" that I needed to go through. I
wouldn't want to do this again but would be willing to offer advice to those
would would. There is a place in Youngsville, Ohio called Lumitex that
actually makes the panels. I got ahold of a sample for possible use in the
MW receiver design and I liked it so much that I threw it into the Lowe
receiver.
What it consists of is a woven fiber optic bundle that emits light. This is
very similar to the diffusing panel that is used in the Drake SW-8 receiver.
You can actually change the color of the backlight by using a different LED
at the end of the fiber optic bundle. I have been thinking about changing
the LED color in my SW-8.
I hope this helps.

The minimum discernable signal on the HF-150 is 0.08uV on all ranges
when
the preamp is switched off, improving to .04uV when the preamp is
engaged.

Could this be the other way around? The radio should be able to
discern a weaker signal with the preamp on, n'est ce pas?

That's what he's saying. A .04uV signal is weaker than a 0.8uV,
and for the former to be noticeable, the preamp needs to be in place.

..04uV is half the signal level of .08uV..........................see what I
mean?

Thanks Pete. That's what happens when you try to read too fast
(I misread 0.04 as 0.4)
