The speaker is pretty good, although you have to cut a a ground trace in
order to bring the AGC connections out to the S-Meter. The preselector was
just ok, in my opinion. In the passive mode, the loss was between 3 and
10dB, depending on the range. With the preamp engaged, the gain varied
between -1dB to +6dB. They did a nice job on the board layout, but that
cheap plastic tuning capacitor was a turn-off for me, especially for the
price that it sold for. Looking inside of the PR-150, it appears that it was
not designed by the same engineer as the receivers. Construction quality is
nowhere near as good as the Lowe receivers.
I traded mine off towards a Lowe HF-225. I did keep the HF-150 though. As
far as the speaker, having a notch filter is a good idea but a 150 dollar
selling price would have been more in order.
Don't forget the "rack unit". Actually, it looks pretty good when you have
it loaded with all of the accessories. Do you remember the advertisement
that Popular Communications used to have for the HF-150? There was a photo
of the receiver, with a Baby Ruth candy bar sitting on top of it to show
just how small the 150 was. There was a caption that said "Baby Ruth candy
bar not included", or something like that. The 150 is still my favorite out
of the Lowe bunch. Once you install a backlight, the receiver really looks
cool.

The speaker is more interesting to me than the preselector. As I
understand it, it's not only a speaker but also a signal meter and an
audio notch.
