I think you mean Hammarlund, John.

I had two of those once. They were VERY nice receivers. I had to sell both, and, as you say, I 
got some very pretty pennies for them.

I also had three R-389s. I have one left.

Yes. It was a National design. I have a couple of those too. One here that I use periodically. It 
isn't as stable or as well built as the RAK, but it works very well.

Yes. I have an HP selective level voltmeter that tunes down to the 1 Khz range.

I also have an RBA, a couple of SRR-11s, and a few others.

And I agree with Mike, they are better receivers for MF/LF than the BC-453....

But I also insist that the BC-453 and R-23(*)/ARC-5s are the very finest single-band receivers 
ever built.

For their size and circuit design, they can't be beat...and there are lots of them still around to 
be used as monitor receivers for the 630 Meter band.

And I can put a dozen or more "ARC-5" receivers in the bench space required by one RBA.
