Don't forget this link for the HF-150 service manual:

I know, this is the second posting of this link, but I feel it is important
enough for all concerned!

On topic, I hope....................Dave Z has just started a Yahoo
newsgroup that centers on Lowe receivers. The URL is:
http://groups.yahoo.com/group/lowe_hfreceivers/

Hi Steve,

You are correct in your assumption. The preselector isn't really
necessary. My statement was purely theoretical.......I think that the
only way you would see a difference would be if you would have a few
signal generators hooked through isolators and combiners, set up at
high output levels and tuned to different frequencies.
This would allow you to see the multi-tone response under very adverse
conditions. Under these conditions, a preselector would help.
Do you need to do this in the real world? Not really, unless you were
using this receiver on a ship where there were several high power
transmitters being used at the same time.

This is interesting. Have you (or anyone else in the group) actually
used a preselector and/or highpass filter with a 7030 and found it to
result in improved performance? The 7030 is said to have such a
robust
front end that additional filtering is the last thing I'd expect to
make a noticeable difference. In fact, I'd expect whatever tiny
improvement that resulted from the extra filter to be outweighed by
insertion loss.

However, I have an open mind about this--as well as a Kiwa highpass
filter, standing by.

Pete,

Of course it's on topic cause they might be discussing the antennas they
use on the 150. I was wondering why there no discussion group geared
toward the Lowe 150 and it's family members!
Thanks

Lucky




Yes

I'm fast!

Yes it is important and I didn't have it. I'll just have to start sending
you money from now on for any new info you post since I can only says thanks
so many times :)

Thanks!
Lucky

I am glad that I was able to get ahold of it...............actually, Dave Z
is the fellow who located it in those archives today. His Yahoo group should
be a good thing.
