Don't forget to put the plastic slip cover on the line before you solder the connection...and in the right direction ;-) I would recommend stripping back say 2" or so of the outer jacket and unweaving the shielding so that you have a fair amount to neatly pull it around the center dilectric...

Anechoic generally have a suspended mesh/net floor, not hard concrete. Maybe some sort of RF absorption baffles? I was in the anechoic chamber at ATT telegraph hill. It is really weird, when the door shuts you can feel the pressure from the seal in your ears and after a second or two, you can...

To get a good idea of how heavily armed the warlords are and the people that are now free to roam with little order...check this documentary out. Ghosts of Cité Soleil (2006) It was horrible there when things were 'normal'. The prison collapsed and the ones they deemed bad enough to keep are...

That Rife link has nothing to do with transmitting on the air....don't do that mod..that's the w5jgv link. That is for a completely alternate use of RF that has nothing to do with talking to people ;-). The 510 and 520 are best not cranked up for power, but modded for loud audio. I ran a...

Just have to watch a few things....the breakover voltage rating, under power you can have 5-10kV at certain tuning ranges easy. Also the amount of time it takes to switch, which can be checked on a scope. Gotta make sure depending on where you put that relay that no RF is applied until the...

Just for laughs too, to add to the pile. You have W2IHY gear there, make an adapter, I'm curious how much audio response is passed by this radio for simplex use. The 7800R for instance rolls off pretty heavily at almost 300Hz assuming the user would always be using it with PL ENC/DEC engaged...

Wow they really put everything into this...thanks, that totally clarifies the audio muting thing I was getting at. The TX muting is even better with regard to APRS beaconing disrupting you on the other 'side' of the radio...well though out.

So for the audio ducking / muting question. More detail. So you have VFO A and VFO B, right and left side of the radio. If they are both up and running. If VFO A opens squelch, is there an option to auto mute VFO B while the squelch is open on A? So say I have public service scanning on B...

Open wire line/window line/ladder line/balanced feeder Advantages are, far lower losses in the line, particularly at high SWR condition. Great for very long runs...hundreds of feet to a distant antenna. Great for wide band tuning an antenna on multiple bands with a manual tuner. Example, a...

Yeah thanks, I was curious if it displayed the frequency at the same time...nice. Does it have a 'priority' mode so that one of the receivers will mute the other or duck the audio level when its squelch opens? I love that option in my VX7R.

Hahah modded already that rocks. Noticed it has adjustable mic gain too OMG what a novel concept that is eh? Cool. My wallet is trembling....probably another month or so before I do this one.

Did the mic actually come with yours? Initially....and very oddly, they were saying a built-in mic in the control head was the only one included. Like to see an example of a full length alpha tag displayed for a frequency too when you get a chance....had my eye on this rig for a bit now. Had...

I run a Diamond SG-7900 now and also have a Larsen 2/70B...it's been really interesting since I've been involved with a 440 repeater setup recently to experiment between the two antennas. 440 is quite a beast to figure out. I've definitely found the 7900 to be better for 2m simplex, but on...

Looks good and solid. What I've found is that if I stick an antenna on my temporary mast which is just a 5 foot piece of pole lashed to my fence and tune it for best SWR, when I put it up in the air, it just gets better. Hopefully you'll have the same results. What CDX said is true, the angle...

Keep in mind, the more gain, the 'flatter' the radiation pattern gets....it gets narrow as a razor. On flat, open ground or slight elevation advantage, this can be great. In varied terrain with rolling hills and buildings, this can actually hurt you vs a much higher angle of radiation on a no...

That's what I've seen from most of the manufacturers... "you broke it, you bought it" basically. So if you do it cleanly, they don't care, but if you cause a failure, it's on you.

I think the hardware mod comes from the "not easily modifiable" clause in the FCC regs. it's really not hard to do these mods, but if you don't have a proper iron with a fine point to get in there and out cleanly...don't do it. It should be a very fine tip 1mm or so and a nice hot iron so you...

You wouldn't likely see much benefit to actual signal efficiency using the rig's compressor after an EQPlus has already been applied. The EQPlus may not be particularly audible when it's compressor is heavily applied, but it's because it uses a really decent analog devices IC to do it...as in...

This is commonly done as part of the bargaining process to get past the zoning commissions. My employer had to bribe...errr employ the local police force 24/7 as an overtime project for a full year in order to get a few things past the local town's zoning board when they opened the site. Of...

O.k. well you should be able to use the D104 by just barely opening the gain and in turn turning down the mic gain on the radio. By barely opening, I mean taking the pot just a mm off the stop of 0 to turn the circuit on. Put the rig at 9-o'clock or lower and just barely crack the D104 gain...
