Easy fix for that, Rick, is to hard-key the amplifiers. You can gate to the right amp with a toggle switch (error prone) or come up with a band decoder to gate PTT to the amps. For that matter, you c

I don't know if others have had the issues I've had with the XV transverters, but I thought I'd report on my efforts this weekend .. I run a stack of 4 XVs driving high-power TE amps in my rover. Ant
sorry about that, accidentally hit send :) I don't know if others have had the issues I've had with the XV transverters, but I thought I'd report on my efforts this weekend .. I run a stack of 4 XVs
Well, it's been a tough spring for me .. took a new gig in NYC and getting ready to move the household back up to 1-land shortly. However, I'm in town this week and plan on taking the Jitney out this
Xtof and I will be firing up the Jitney for a run on Saturday and Sunday .. not the usual route, as I'm in the process of moving and things are pretty crazy. Proposed schedule: FM09 1400 1530 Elkins
Need 4 SPDT N-connector relays for low-band T/R in the Jitney. 12 or 28 V fine. Please email direct (john <at> sort <dot> net. tnx de w1rt/john _______________________________________________ VHFcont
I inherited a true sinewave inverter, an Exeltech 1100, and its inside of a pretty tight box along with a Jacobs Accuvolt with feedthroughs for 12V and 110V. Bill did a great job on that box, and I r
Anyone know anything about this relay? It's got N connectors, but I'm trying to determine whether it's latching or failsafe .. de w1rt/john _______________________________________________ VHFcontesti
I'm curious where you get your eleven foot figure? I've been running about 11 1/2 for a couple years now, and Bill ran even higher than that. You've got to pay attention to the bridge height signs, b
I just ignore the grid circler's scores when looking at my results .. plenty to do to reach/beat W3IY and K8ISK performances from the past The captives don't bother me as much .. though I am planning
You also can't load those pneumatic masts too heavily either, and water retention and freezing has been a problem for at least one rover I'm aware of. I adapted a 20 foot crank-up pole (army surplus
I believe the discussions so far would prohibit relayed APRS .. the fixed station would have to directly receive the rover's APRS packets .. I don't have a problem with it, but without widespread ado
I've been working on my route for the last few days, and I've been using the 'My Maps' feature of Google Maps to help. You can see the map in it's current state at: http://maps.google.com/maps?ll=42.

One way to avoid the $140 relay is to visit your local boat store and pick up the very nice rotary switches they carry for controlling batteries and generators afloat. I've got a single-pole switch b
Steve, check out IOTA chargers .. very reasonably priced, handle AGM just fine. I use a 35A version for charging the Jitney (4 T-105's in series-parallel) de w1rt/john _______________________________
Those were LiPolymer batteries, not AGM .. so it's unlikely that's what Steve has .. de w1rt/john _______________________________________________ VHFcontesting mailing list VHFcontesting@contesting.c
Matt mentioned it upthread .. look at the Jacobs Accuvolt. I've got two in the Jitney .. one runs all the time and is enclosed in an RF-tight box along with an exceltech inverter. The other runs the
Frank, using the Accuvolt to get one more db isn't the point .. many current-model radios get very flaky/unstable/weird when running much below 12.5V .. FT-100 is a good example. The Accuvolt lets me
