Re: [IRCA] more same stations, different receiving setups



Gary -


Your original comment was that the loops required extended setup time. I hope you'll now agree the flag / corner fed loop has trivial setup times.

Thanks for your comments.

Actually a single large FSL can be set up on its PVC base (a.k.a. "Walker") within about 2 minutes, and was done so a couple of times at the cliff (Saturday and Monday mornings) resulting quick loggings of 1017-Tonga upon first arrival at the site. The FSL setup only takes serious time who you deploy four of them, complete with PVC bases, PVC radio holder frames, plastic totes, Ultralight radios, digital recorders and connecting wires. Hiroo Nakagawa was amazed at this extravaganza, and after watching it for a few minutes did the complete disassembly for all four PVC "Walkers" on the last day.

I agree about the FSL's.

The deltas / loops are really not big for the cliffs. You could put 10 of Tom's deltas in Rockworks 4 if you had supports. I could make my 18x18 flag 6 times longer if desired.


And my jury is still out on the active whip after listening to the recordings of weaker stations. Nick may have to be a big spender and go for the 6' or 10' element. I'd be curious about using the standard 102' cb whip which should mount onto the AMRAD unit.

The large (for the cliff) broadband loops used by Tom and Chuck are superior performers for relatively sensitive investigation of the entire MW band, but do require some extended setup time (in comparison to your active whip and the FSL's), and have some weather vulnerabilities (in comparison to your active whip).

Your active whip provides generally good performance in covering the entire band, and excels in quick setup and weather survivability (as we all found out on the "day of the drowned rats").

The FSL's do require manual tuning (with the related weather hassles), but they provide unexcelled low band performance, extremely quick setup and have a huge advantage in performance for the compact size (they can be set up in one square yard of flat space).

Of course, all of these antennas get a DU-DXing performance boost when they are deployed at an ocean cliff site, with its solid-rock attenuation of back-side domestic signals and transoceanic signal boost. Related to this, I hope that you will post the results of your July 11th comparison of the ocean cliff propagation with that of the sea-level campsite nearby (in which the Rockwork 4 DU-DXing results kicked those of the sea-level site "off of the cliff").
