Greetings:

I just read about a kit called the HI-PER-MITE on another eHam.com forum.  The same blurb also mentioned the Autek audio filter.

I'm interested in the HI-PER-MITE as a possible solution to a project idea I have.

Anyone here have any experience with this kit?  How about the Autek audio filter?

'ppreciate any comments.

Hi Al, you can find tons of comments on the Hi-Per-Mite or Hipermite here and on various QRP groups. I've never read anything negative. I use a heavy power-gulping outboard timewave filter with my little QRP radio and have thought about building a Hi-per-mite into it. My Timewave cost more than the radio and uses more power! Auteks go back 30+ years.

Also an exhaustive test of the Hi-Per-mite:

Re:K8AXW

In addition to my response to your question in the other forum I failed to mention the Autek Filter. Mine is about 30 yrs. old (QF-1A) it's AC but will work off 12VDC.At the time it was a very popular SSB/CW/AM filter, still is to some hams. Due to it's 4 controls and various settings for each there is a bit of a learning curve to use it properly. If anybody picks one of these up try to get manual or copy with it. If I recall there might be instructions on the internet.

Jeff:  Thanks for the links.  I've been reading about the HI-PER-MITE and it sounds exactly like what I need.  The price is incredible and a guy couldn't replicate it for that.

JKA:  Also read some about the Autek.  Might consider that one of these days if I can find one on eBay for a reasonable price.  What I really need now is a a very small PCB to go into an existing project that has just a switch to enable/disable it. 

Thanks guys.
