[digitalradio] Open wire feed line length

2008-07-02 Thread w4lde
After reading several articles both on and off the WEB regarding a center fed antenna, only one article mentioned a recommended length for the feed line. My shack is located on the second floor of a new home, (24') #8 ground wire to 8' ground stake with a further connection to the common

100 feet of ladder line is sort of a magic number for being easily tunable on all the bands. One of my friends bought a ready-made 80M dipole with 100 feet of ladder line and a tuner; and the instructions were not to cut much if any off the ladder line. I learned the reason for that later when I

This is quite off topic, but hopefully the moderators will cut some slack since even digital ops want a good antenna like anyone else:) I do have some experience with using a modified form of W6JJZ's, The Suburban Multibander. This antenna is described in the ARRL Antenna Compendium, Volume

I have used that multiband antenna configuration both at my home station (140' doublet, 450 ohm ladder line, 1500 watts) and when travelling (70' doublet, 300 ohm TV twinlead, 100 watts). My experience: 1. Balanced tuners (e.g. the Johnson Matchbox) work better than an unbalanced tuner and a

Where practical and available, instead of using a split-core ferrites, use a ferrite toroid. The split core will never achieve the level of magnetic coupling between the two halves that the toroid will, with its continuous magnetic structure, and all else being equal, that makes the toroid a

If most PSK operators are interested in rag chewing -they need to move on to a better digital mode. PSK and RTTY are the two worst modes available. And that's the problem. Too many people, groups, and leaders in the Ham Community promoting OLD and less than effective modes of communication. I

Anyone successful at Easypal (1 Jul 08) and Vista Home?? I have no problem using HRD/DM780, but EasyPal will not key my radio. I'm sure there is something I am not clicking or setting to make it happen. Thanks, Don KA5DON

On what basis do you claim that Olivia, DominoEX, and MFSK are better than PSK for ragchewing? Olivia is slow, and MFSK is difficult to tune. By design, DominoEX addresses both of these issues, but at the expense of increased bandwidth -- which makes panoramic reception less attractive. You

Its difficult to make a QSO in the newer modes because they aren't better enough than PSK or RTTY to motivate a broad-scale transition, so their use remains limited to a small number of afficianados. When someone develops and deploys a mode with significant improvements over PSK and no
