Okay, here's one prompted by some questions from Randy.

What's your lowest-powered catch via prop mode?

For Es, I have four under 100 watts:

34w 103.5 K278AO Trinidad CO 988 miles, 6/18/2005, w RDS
40w 88.3 K202CV Breckenridge CO 842 miles, once in 2004, once in 2005
50w 92.3 KWCD Bisbee AZ 1064 miles, 5/27/2005
58w 90.9 KWRB Bisbee AZ 1064 miles, 5/27/2005, w RDS

For Ms, my lowest power is:

290w 92.7 KHWK Tonopah NV 466 miles, 7/5/2005, w RDS

For Tr, my most impressive catch is:

28w 102.5 K273AA Kamiah, Etc. ID 283 miles 11/9/2004 - May have been Au, as Au was also present at the time. Given the topography between here and there, I'd almost guarantee it - but the signal was too clear.

What are some other long-haul, low power catches on FM?

Some of my lowest powered Es FM is 93.5 WSBG Stroudsburg, PA 550 watts at 968 miles (Hi Russ!) from Aug 2, 2005 coming in at the same time as 100kw KKOT in Nebraska which took a dive just in time for call letter id, both heard in the audio. Some of the Jamaicans and other Caribbean I get may be lower though. I'm pretty sure I've had 350 watt Radio Cayman 2 on 91.9 and may have had a 50 watt New Mexico translator at around 1000 miles. In January 2006 250 watt 95.3 YNF3LL from Leon, Nicaragua at 1244 miles was in for a couple minutes on an exceptional off-season sporadic E opening and set a new record for me.


For tropo I occasionally get 38 watt W230AM Montgomery, AL on 93.9 at 132 miles which relays WKXN Greenville, AL.

most notable tropo distance / power is 1500 watt XHTVR Tuxpan, VER, Mexico on 106.9 at 936 miles heard a few times since fall 2005.

On meteors 101.7 WCCL Central City, PA 720 watts 798 miles

Hey Dave I'll bet I have you beat on the HIGHEST powered FM :D
Here's 300,000 watt 99.7 WMC Memphis, TN at 376 miles from last weekend. It was the only station from Memphis that could burn through all the MS and AL stations.

No way, Randy!

CITI-FM is 360KW on 92.1! :-)

Arggg!! You have me beat, Dave. Hands down.

My best contenders are a couple of translators via Es, both on 88.3 but heard during different openings:

K202CJ NE Deshler 1186 mi 250 watts
K202DC OK Shattuck 1361 mi 230 watts

I have a couple of other low-power Es catches but don't have the info at hand. I'll post those later - I'll have to rummage around in the shack to find the scrap of paper they're recorded on...

Es, non-translator division,

90.5 KTLN LA Thibodoux 1132 mi 200 watts
91.7 WVIJ FL Port Charlotte 988 mi 680 watts

Tr:
W219BB KY Owensboro, 92mi., 60w

Es:
K228DL CO Wray, 857mi., 70w (heard twice)
K202BP KS Bellaire, 671mi., 80w (but the antenna is lower than K228DL)
K206BN MT Ashland, 1165mi., 220w (heard twice)

Adding to this thread after it's been dormant for a bit.

I recently confirmed a logging of K232CK (//KOPB 91.5) Hood River, OR.
They are 112 miles from me and 40w directional; given their polar plot it looks like they throw around 20-25w my way.

I have had OPB on this frequency for a long time... I thought it was just an intermod product from my local KOAB mixing with someone else. However, for the past month or so KOPB Portland has been running about 5 seconds behind KOAB (weird, of course, because KOPB is the flagship station of the network). Anyway, K232CK is also running behind, in line with KOPB, so I was able to rule out intermod and add this logging.

It's amazing what you can do with a nice HAAT (K232CK has 383m/1257') and line of site reception (tower is at around 2600' ASL, I'm at around 3200' ASL, and there are zero mountains between here and there).

This is the problem I have with translators and LPFMs in this area; the FCC has handed 'em out as if a 10w or 50w signal travels 10-20 miles or so. HAH! I've had 2w (yes, two watt) KPOV-LP from close to 60 miles as I travel between here and Portland; FCC shows their primary contour as not even covering the entire city of Bend. :duh:

IBOC.

KOPB is listed as IBOC-licensed and on the air. There's a coding delay in the digital exciter, and the analog audio is run through a delay line as well. That way, HD radios can blend to analog if the digital signal fades out.

The delay happens at the transmitter, so the uplink KOAB carries isn't delayed. No Oregon station outside Portland is IBOC-authorized at this time.

Thanks Doug!

Makes perfect sense. And I don't know how I forgot the DXers golden rule: when in doubt, blame IBOC... ;-)

Not mentioned is anything low-powered via AURORA propagation.

Back in the late 60s when living in Milan MI, I once heard WSUP-90.5 Platteville WI (430 watts) via aurora.

Translator ERP's can be elusive, but I'm sure I've had at least a couple ten-watters (years ago). I once heard one from Gage NM which was on 95.3 at the time - I don't think it exists anymore. Also a Coalville UT KPCW translator (on 88.1) which I think was supposed to be 10 watts, but Ralph Strobel also heard it a few years earlier. Surprising we'd both hear a ten-watter like that. Even more astonishing, I believe it was Ralph's CATCH #1000 at the time, which made it all the more special for him.

I had 230-watt Pinedale WY 101.1 loud during an opening this year (as well as second-timer 49-watt Wadena SK 103.5), and I heard similar-powered KWUF-106.3 Pagosa Springs a few years ago, 220 watts I think. I heard WVST-91.3 (with my local off) when it was 100 watts, and WFNM-89.1 PA as well.

That 1500-watt Veracruz station at nearly 1000 miles via tropo is very impressive, wow!!!

In the late 70s, WUIC-88.1 and WHPK-88.3, Chicago ten-watters at 205 miles, were reasonably COMMON DX catches from Toledo, Ohio. I believe that WRRG-88.9 in slightly farther River Grove was my 10-watt tropo record.

After sorting out the 2006 Es season I broke my low powered Es records several times. Nothing like some of you fellas have though.
My new record is 100 watt 91.5 XHDRO SAN PEDRO, COAH, MEXICO at 1067 miles. Also 2 different KJIL translators in KS & CO at 170 and 182 watts this summer. 250-500 watt stations were rather frequent this season.

Looking back at my log from this summer, my lowest powered Es catches were....

10w 93.5 K228DK Deming NM 1093 mi 66' HAAT, 6/4/2006 w/KRWG ID
50w 100.1 CKFU Fort St John BC 692 mi (unknown HAAT) 6/15/2006 "The Moose"
100w 91.7 KGLP Gallup NM 883 mi 1043 HAAT 3 times in July
170w 93.5 K228EE Elkhart KS 1193 mi unk HAAT 7/4/2006 (Randy got 'em too)
About 15 more under 1KW, mostly translators. Nothing quite like 10w Es though!

Still the same "record" for me on Ms as below - KHWK Tonopah NV at 290w.

For Au my record is 93.5 KOZI Chelan WA at 590w and 282 mi. This was heard during an aurorally induced radio blackout while my only FM receptions were Au so I count it as Au, though I have had them one or twice via Tr as well. All of my other Au receptions are 10KW or better....

I broke my low powered Es record with 20 watt 97.1 W246AL Wellsboro, PA at 938 miles on May 9. The signal lasted an amazingly long time with very little fade.
Also 99 watt 101.7 W269BK from Horseheads, NY at 974 miles was in strong just before. Recordings attached.
