FCC runs out of LPTV callsigns (kinda)

High-VHF channels have always been popular for translators in the West. The DTV conversion bumped many to new channels and got us pretty close to the end of the alphabet in some places. K07ZR (Harlowton, Montana); K09ZB (Havre, Montana); and K13ZS (Sargents, Colorado) were assigned. I figured the re...

Re: Low resource SDR Software

I have (I think) the same hardware as Kevin -- the SDRPlay RSP1. I'm happy with it. Good strong-signal handling; with a 260-foot center-fed antenna attached, not a hint of spurious reception in either the AM BCB or shortwave. (or FM although it's clearly not an FM antenna:) )

Re: Bleed over

IMHO you need to break this down step by step. I suspect you may have more than one problem. I think what I would do... is *turn off* the 1240 transmitter. Turn up the levels on the 1240 audio and see if it still bleeds over. If it still bleeds over with the 1240 transmitter turned off... you have a...

Re: Low resource SDR Software

Well. This is going to take awhile:) There was a dramatic improvement in conditions as totality approached. At 1645z (roughly 90 minutes before totality) most of the expanded-band was empty -- there's a weak signal from Huntsville 100 miles away on 1700, and a poor signal from the TDOT TIS stations ...

Re: Low resource SDR Software

GQRX is supposed to work with either RSP unit & OS/X. I don't have a Mac available so haven't tried it.

Re: Low resource SDR Software

I've got a low 160m dipole connected to mine. (oriented east-west but at its elevation I'm not going to predict the directivity, if any!) The site is pretty quiet. Diddling around with it last night I was surprised how well it hears on *FM* -- stuff like Evansville and the Nashville Catholic LPFM 25...

Re: Low resource SDR Software

This is probably off the mark but... What are you recording to? Internal HDD? I'm doing essentially the same thing, but using a fairly beefy desktop. (HP Z400) Using HDSDR since it has a decent scheduler and I cannot be home during the eclipse. I wanted to record to an external 5TB USB HDD. Unfortun...

Re: Mounting stuff to old concrete block wall?

(It's not really mounted horizontally, the phone decided to rotate the photo & I'm too lazy to reformat it...) As you noted in that photo, the socket was mounted but there weren't any wires connected. I'm a Grade A procrastinator. Finally got around to wiring it this afternoon. The dryer cord was l...

Re: EAS Antenna Issue

Good advice from "vacuum tube", about reorienting your antenna. If you can get your hands on a HD radio, they frequently have *amazing* selectivity. Are you sure you have to monitor 104.9? It is possible the Michigan EAS plan allows for an alternate monitoring assignment that's not subject to interf...

Re: E-skip 7/27

That you do!

Some things that aren't really 6-meter antennas may work surprisingly well on 6 meters. I've made trans-Atlantic QSOs using my HF tribander and an old 2m 5/8 mag-mount.

Re: E-skip 7/27

Yeah, there was extensive tropospheric propagation being reported around the Great Lakes for a few days as well.

Re: E-skip 7/27

Ham radio reports are showing widespread sporadic-E again this morning across North America on the 50MHz band. I'm not hearing of anything in the FM band yet but "yet" may be the important word. And I still can't remember the hostname for my SDR. (despite looking it up & writing it down before leavi...

Re: E-skip 7/27

Heard a few signals on the car radio while driving from work to the gym, about a half-hour ride through West Nashville & Bellevue. - 88.5 religious - 91.9 two stations, one rock - 92.3 KQRQ Rapid City, South Dakota (legal ID @ 6pm CT) - 92.7 - 93.1 country, probably KRCS Sturgis - 93.5 - 93.9 "93.9 ...

Re: Mounting stuff to old concrete block wall?

When you're all done, you'll find the dryer's cord is 6 inches to short to reach the new outlet. Or as my wife would say, I tried to add an outlet, ended up replacing the roof. Please don't say that:( KPJL FM wrote: ↑ Thu Jul 20, 2017 8:28 am When you're all done, you'll find the dryer's cord is 6 ...
