 seanee | Anyone have suggestions for a mobile antenna that would be decent at HF. I understand that shortwave is problematic for mobile reception | 21:18:50 |
 sa2kng | the mini-whip is very broad band, but quite sensitive to interference. there is mobile hf antennas for tx, like ATAS-120 and the like, requires trx that is capable of tuning them. there is the manually tuned ones like the buddistick but these are narrow and tuned | 21:48:15 |
| sa2kng | for portable use I'd say light weight wire dipole | 21:48:54 |
| seanee | Sorry, I was unclear, How about car mounted ? | 22:12:27 |
| sa2kng | the basic design is a monopole with a coil/inductor that tunes the resonant frequency down. the capacitance of the element and inductance of the coil forms a resonance at the frequency of interest. these are inherently narrow band thou | 22:19:55 |
| sa2kng | you can probably get away with a CB antenna for RX at HF, it will perform a lot worse the further away from the design frequency you get. | 22:22:16 |
| seanee | Thanks | 23:38:01 |

 Sky King | Anyone know good programs for decoding digital radio? I have DSDplus but it doesn't work very well I find. | 01:35:52 |
| seanee | It really depends on what sort of digital radio you are trying to decode. Unitrunker + DSD+ works pretty well but you really have to dial in the frequency (adjust the ppm, etc.) | 15:51:01 |
| seanee | I’ve moved from unitrunker to the very awesome SDRtrunk ( https://github.com/DSheirer/sdrtrunk ) for its APCO25 Phase 1/2 support | 15:55:22 |
| seanee | It has the decoder built in so only one application to configure and no virtual cables to muck with | 15:56:54 |
| Sky King | Thanks, the virtual cables were annoying to deal with. This looks much better | 16:02:36 |

 yalekthelembine5435 | VB audio cable is actually a driver | 00:34:32 |
| yalekthelembine5435 | It also is supposed to increase decoding performance and rid of most erros | 00:35:14 |
| yalekthelembine5435 | having multiple soundcards is a pain | 00:35:24 |
| kmcdon changed their display name from notbrad to kmcdon. | 14:52:23 |
| yalekthelembine5435 | I just use vb audio cable and speakers only. Stereo mix and microphones end up mixing up outputs when recording elsewhere. | 15:00:02 |
