Does the O II have a back up battery that is good for seven years? Many rigs start to have troubles due to that after some years of non use. Stuart Rohre K5kVH
Failures where they do not do closer than board isolation are concerning to us hams. We all want to know what and why the failure? Sounds like you were doing most things to prevent lightning damage.
A beam or wire antenna of half wave or less CAN build up a static charge enough to do real damage to a radio left connected without protection. You need to continually discharge the antenna across th
Connie, What you are missing is you need to constantly bleed off static that is induced and charges up a dipole or other antenna like it was a capacitor. The static can come from wind vibrating your
Connie and anyone new to the list. The National Electrical Code covers safe practices for home wiring and radio hook up to antenna and/or a mast. Technically also, ALL grounds at a house must be bond
Connie, did the tower have ground rods also at its base? That is standard, to ground the tower with its own ground rods, but also Bond the tower to the station ground. See the White papers on groundi
The pay pal message copied to the reflector sounds like phising text received here in past few months. I don't have an active pay pal account, ie never put up cash to them. I suspect it is a hacker t
There are a number of diodes in the Scout concerned with SWR measurement and others for ALC. Check ALL diodes. ALC light should NOT stay on solid. Help is just a phone call away to Ten Tec beyond tha
Hi James, I have just the schematic and even those I think are partials, ie the Jones filter is a "box". Not high quality drawing, faintly printed. Ten Tec would be the source of manuals. But, have y
If the LC band filters are switched by relays as they are in many smart rigs, it could be a stuck relay, or open relay. It may be that both of these bands use a common switched filter. Stuart Rohre K
If the radio audio sounds clean at one point and is distorted once leaving the radio, I would check connecting cables for a bad ground. This if present could cause RF feedback and distort the audio.
This surface mount failure if that is it, might have been from wind building up static on the antenna. Just another reason to disconnect our rigs when not in use, from antennas. Stuart Rohre K5kVH
That is correct about grounding the shield of the coax is not enough anymore to prevent damage. Static charge can build up on either side of a dipole, and when it gets high enough has been seen to ar
All Astron supplies I, or my club have owned have had terrible quality control and really off the wall circuitry. I have had them act as lightning sinks on more than one occasion, either at the club
Certainly relays can be a failure point. Sealed relays in modern rigs may still arc or oxidize at the contacts, and I have even seen relays that were not seated to the solder pads fully, before the b
You can put outboard band pass filters to limit some of the problems of being close to other rigs. However, if you have two stations the need to be close, let one run vertical polarization and one ho
Ralph, Here in CenTEX we did a several year evaluation of loops for FD, using the 75 m loop on up at 20 meters and up. The nulls seem to fill in sufficiently to make it a good gain omni antenna, whic
Sometimes entering a part no. from the component in Goggle search, with quotation marks around it, will direct you to the manufacturer, and to the stocking distributors for it. Stuart Rohre K5KVH
