Mount it on the bulkhead grounding plate and run a phenolic rod through the wall with a handle allowing the short ground path, yet the convenience and safety of the inside actuation. I have too many
Cable leakage is easily identified by listening on 145.25 which I believe is the audio subcarrier for channel 18. What it'll sound like after they go digital? I don't know. One thing I do know. If th
MOVs are the equivalent of a clipping diode and protect from spikes. They do little if anything for filter out noise and I've never head of them being used for that purpose. They are often used to pr
Having been a project manager, I found one of the main problems is many engineers have tunnel vision even without the specialization with in their fields. It's a fine line that divides focus and tun
I don't know about you, but I want a lot of head room when running a KW when I get near the band edges. I've blown out more than one balun albeit, never a choke balun. <:-)) 73 Roger (K8RI) _________
I would think that most in the VHF - UHF range would be easily overloaded and blocked. They may not decode due to being blocked, but one being next door to a 440 system might be down most of the time
So a simple carrier at the wrong time could/would put the enter system out of commission for up to an hour? My take on a lot of these systems is they could easily be overloaded/blocked with medium to
On that is very common is some one with cable and an outside antenna not wanting to bother with an A/B switch. They just wire the to cables together at the TV, or sometimes use a combiner. This invar
There is a thin band, or very narrow range where the signal breaks up, pixelizes, pauses, or goes out of sync between the audio and video, but it is so narrow it is seldom seen. When the signal reach
BTW I've been using cheap old Radio Shack remote amps, but they were running $50 plus. I use those as they only last a couple of years with all the lightning around here. 73 Roger (K8RI) ____________
I've been following this thread for a while plus one contribution...so... When you say "out int he woods", are the stations close (strong signals), far, (weak signals) or a mix? Are they all (more or
As I mentioned in the other post, I run a KW up through 144 into the array and up to 160 watts on 144 simplex on the Diamond, side mounted vertical. Normal power is 2.5 to 5W for the repeaters http:/
I've been driving a 99 4-Runner since 2002 (After a GMC Gimmy pulled out in front of my TA on the highway. Put the right front wheel back to the seat and all the antennas pointed straight forward) I'
I asked about the rig at the dealers and they installed it for me at no extra charge. In the 4-Runner the rig is under the driver's seat with the wiring under the edge of the carpet and through the f
I wonder if that was common to the new model or just that particular unit? 73 Roger (K8RI) _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.
I don't believe there is a more effective capacitor made than that big automobile battery. 73 Roger (K8RI) _______________________________________________ RFI mailing list RFI@contesting.com http://l
How about building up one of those "doppler shift" antennas? I've seen them used on 2-meters and for close in work I'd think it could be adapted to 20. For years I've chased what at times can be an o
I've never seen the circuitry, but how did the old ADF equipment work? Might it be adaptable with a computer and display to display and overlay on a GPS moving map? 73 Roger (K8RI) __________________
I'm referring to ADF, the old set of VHF, vertically polarized dipoles on a pole that you'd see at most major airports. No loop was involved. When you keyed your radio the ADF display would show a li
