I agree... IF the radio is set up to care. Most radios only look for squelch opening. I

Rich - did you clip at just above the coil or at the tip of the whip? A shorter length should work just over the coil, or better, zo's round hat just over the coil. Good luck in any event.

HI Gang, I have purchased Inrad(Collins) CW filter and the expirimenters Collins SSB filter from Inrad. The SSb filter is the same one for the 817 with out the PC board. If the ceramic filter is

I have been hearing some rumors from some Hams in "VK Land" about the ability to increase the output of the 817 through a "hidden" menu. Anyone heard anything else about this. I'll be on a "QRP

Hi Pres, My '817 will stop 5KHz off-center every time, if the signal is good & strong. A'course, I need to send it in for birdies & noise blanker work anyway, so I guess I'll mention this as

Yea - that is curious isn't it - - I suspect that it is the same syndrome that is affecting lots of engineers these days - engineering to the edge of the envelope and not allowing for any slop -

I was just perusing my new service manual ( yay! ) and looked into the alignment menu. Seems there is a FM discriminator center alignment. Now, I don't recall any zero-center display so this leads me

The '817 doesn't consider the SWR to be "high" until it is over 3 or so bars - but that doesn't mean that it won't cut the power back before then. What would be interesting to find out is if the

I have used a 7 amp gel cell in auto cig plug and no damage to battery, but I only did this with one that is charged. I would NOT plug up my discharge 7 amp gel cell in cig plug. Also I would not

Question: What if you added a solid rod about 12 inches long on top of the coil, then put the whip on top of that. Aluminum rods are cheap and should be able to find one the right size. Then just

All in product marketing I would guess. The longer the whip, the larger the base diameter must be, right? And a larger base might not fit on the rig's BNC because it would bump against the SEL

Hi Mike, I have an Amcom Base DSP Unit, I opened it up to look at the board. It looks like it would fit in the area where the battery pack fits. Unfortunately due to work commitments, I'm not in a

Don't connect the gel cell directly to the cigarette lighter plug without some current limiting! You could blow up the gel cell!! Phil - AD5X and amp it

Hi Hans, Not in your wildest dreams is there space. The ceramic filter is small and tightly pack into the PCB, and the SSB filter is LARGE. Now if you are willing to remove the speaker then you

I didnt believe, that it will happen because I never got response from super antennas BUT this morning I got a phone call from German Custom: a big package of MP-1 antennas arrived at Frankfurt

Has anyone tried the Miracle Antenna? Not a bad price if it works - just don't want the be the first on my block. Jerry Steele K8CMI

You're right on the money with the battery life, and thanks for the tip on how far down to go on the voltage. This is what I was trying to ask: A) Will connecting the battery and the radio in

Alkaline AAs don't seem to hold up unless you are using one of the lowest power settings on the FT-817, but lithium AAs do better at the higher power settings. Sure, they are not rechargeable, but

Hi Pat... First, get rid of those duracells, anything less than a high rated NiMH cells/pack is a waste of time ( unless you just want to listen!) If I understand your question right, your asking
