In addition to our 2 olde L-Pers, our resident engineer created a 3 element Yagi out of PVC pipe and a tape measure. I used it last Wednesday on a non-distress search, and it worked great. Except I forgot about the fact my HT would only do a receive mode, not DF. And that in this mode, the strongest signal would be to my right as opposed to straight ahead. And that's where the ELT was ultimately found: 90 degrees to the right of where I was convinced it was. I didn't realize this until this morning.
Still a major after all these years.

^^^My thoughts exactly when I saw that in the Volunteer. I recently ran some homing trials. Blue Box L-Per, Cheeseblock L-Per and Sniffer had 100% finds. Pro/No-Find had 0%.

For on-airport ELT hunting, I've had my best and most consistent results with a scanner and a "rubber duck" antenna. Body shielding works!

This is where we'll be getting ours:  http://www.rdfantennas.com/products.php

Currently showing the MK4 (temp) out of stock.  What would be needed to merge a MK4 into an L-PER mast/element setup?

Figures.   We budgeted to buy one this quarter...!@#$%

No idea on the antenna, we're just going to buy the handle combo with the MK4 (assuming we can get one).

Truth! And by adjusting the frequency, you can pinpoint a shelf that the thing is sitting on....

I just bought the Mk4 Version 4 direct from the manufacturer in Australia, the price with shipping was about $170.00 as opposed to the $295.00 from rdfantennas. I'm still getting the antenna from Bob Miller, but I try to save money where I can.

Oh wow, awesome - it's not my money, so any savings are appreciated.

It also appears the manufacturer ships with newer firmware.

This may have already been posted.  Definitely a different tool from the L-Per.

I agree. I was solo on a return Mx ferry flight and had to divert for weather, and as I was landing at the airport I picked up a 121.5 signal. After I landed, since I had nothing better to do, I grabbed my portable air band radio and had the hangar where the signal was coming from pinned down in less than 5 minutes.

Goes to show how fundamental skills still need to be encouraged rather than fully depending on technology.
