RSP1A or better and don't look back.

0306 - some rant. S6-7, good audio, QSB

64
2349 - backsell Aerosmith - S3 but strong audio.


65
2357 S5, QSB, Sultans Of Swing. Good signal, audio punches through the noise

For $10 each you can add one of the inexpensive Distill brand AM notch filters and the FM notch filter from Amazon. I have both and they work well in addition to the onboard RSPY1A radio filters. Don't turn on the Bias Tee into them. :-)  The AM one cleans things up well enough to allow me to pick up WWVB on 60Hz with a low wire and several NDBs.




For less than $20 each you can get the NOOElec filters with the nice enclosures, from Amazon as well. I use the FM Flamingo one to kill all the residual nearby FM broadcasters so I can listen to Satcom on 260MHz with the RSPY1.

It is an amazingly good sounding vintage glam-wave radio.

Find a three prong computer power cord (IEC power cord), chop off the end that goes to the computer, strip the jacket and find the green striped wire or if there isn't a green wire, use a meter or your tongue and a 9v battery to find the ground wire, cut the other two wires back, tape them off for safety, plug into outlet and connect the remaining green striped wire to your radio ground. If it doesn't make any difference or creates more noise, throw the cord away now that you've ruined it for all intents and purposes. What were you thinking?


The thing about mag loops is their relative independence from ground plane or earth since it works in the magnetic field rather than the electrical field of signals. In other words, a true magnetic loop of good design shouldn't need to be grounded. That said, the MLA-30 is a noisy antenna due to design shortcomings. https://www.g8jnj.net/activeantennas.htm#MLA30



See this - You could actually make this or buy it here: https://airspy.com/youloop/ It's a passive antenna so no pesky amplifier to deal with. It's the same price as the MLA-30. And, if you must have an amplifier, for a few more $ you can get a wideband LNA. You could even get one that is bias tee powered and use your MLA-30 injector to run it.


Good luck! I actually did make the IEC cord ground cable thing, but not for receiving. It's  chassis ground for my Spitfire AM transmitter. Doubled the range and almost eliminated the hum.

Got the Vast V-FMT212R on the way to replace the Ramsey FM-25Aand allow me to play with RDS/RBDS, fingers crossed... Is USB powered and power adjustable through the control software from 0-200mw. Will pass the audio from RadioDJ to StereoTool to Vast using VB Cable via USB so all audio remains in the digital domain from player to transmitter. Should be interesting.


Update:  Got it last night. This thing is pretty trick.
  • has integrated antenna matcher
  • very quiet when idle. No pesky hum problems like the Ramsey xmtrs
  • Has has a minimal audio compressor/limiter (not using)
  • RDS was easy to set up. Picks up the song data from RadioDJ.
  • has web interface for controls
Too bad there's not a MW version.

10/11 meters / Re: 10M FM repeater activity

1312 UTC

Listening to some repeater on 29.620 FM S5 signal. Hope it's KQ2H. Spanish conversation, sounds Puerto Rican.


Also some traffic on 29.600 FM S3-6

Not sure I understand the need for 3.8GHz coverage for a cheap antenna analyzer unless you are doing some sort of low band satellite or whatever. If it can do HF through UHF, I'm good.

RadioDJ here. Has all the tools and ability to categorize liners, sweepers, TOH IDs, jingles, etc. You can create your own categories and really fine tune things. I like the ability to treat an internet mp3 file as a track and schedule it to play, for news, etc. Rotation functions are nice. Track import is slow, but to start, I just pointed it at the music folder and walked away while it figured things out. You can create events to fire at specific times to automate series of functions like stop, start, play, load different playlist, etc.


Rather than generate playlists, which RadioDJ can certainly do, automatically or manually, I let it free run in AutoDJ mode, which uses the rotation settings to generate the playlist hour at a time or so, and have rotation/separation rules set to keep artists and song title repetitiveness down.


I create specific rotations that include tracks from different categories, like Rock, Classic Rock, 70's, 80's, Triple A, AC, and stick the jingles and liners elements in there as well. All the different positioning elements can be put in separate categories and let RadioDJ pick the oldest to play next.


Mine is really just a jukebox for me to listen to around the house or outside, on pillow speaker at night to kill tinnitus. I do stream it for fun here http://s2.free-shoutcast.com:18594/ so I can listen on my phone or laptop in the backyard, or Sonos around the house.


The event function, for example, I use to do the news block. It is two events, one to start the newsblock and the other to come back to music. The first one stops the play, plays a liner, then loads a playlist that kicks of the news URL playback. Then at 2 minutes in, it kills that and goes to a promo or ID, then depending on what hour, either goes right back to music or plays the time announce, kicks in the AutoDJ generated playlist then Play.


It is possible to automatically create playlists that fill the hour so you can let it backtime to the TOH news or whatever. I'm still honing that. What I do know is that the news service I pull in at :55 has probably the most inept news readers I've ever run across. They can't hit the 2 minute post to save their lives, and they can't apparently read very well either. Oh well. You get what you pay for :-)




just adding to this post rather than creating a new one - other things that are useful in RadioDJ


Can edit start/stop/crossfade point/voiceover in any track in the app
Runs on MariaDB which is super light and free




Having used several different software radio automation platforms starting with AXS in the mid 90's to BE AudioVault, to Prophet Wizard for Windows, to Nexgen, this free RadioDJ is damned impressive. (actual first automation experience was with a Harris system incorporating Instacart, Carousels and Otari reels running TM Century formats, but that is ancient history)

2120 - Noisy, S4, QSB in S. Texas. - The Wall. Audio is good quality.

Part 15 AM and FM Station Operation / Re: Part 15 AM and FM

Pinole Community Radio AM1610 on the air for 4 years 24/7 with Jazz, Blues, Vintage Country, Bluegrass, & Oldies. And of course all the important stuff that entails the city of Pinole, Ca. Our distance is pretty good. 1 1/2 miles with a Procaster.

https://www.facebook.com/pinolecommunityradio/


How do you have the Procaster set up? Just curious about grounding, etc.
