Gary, I had the misfortune of getting 2 new D-808's recently, only to discover they are the new 'unimproved' model. Mine still had Micro-USB connectors, rather than a C-USB. Apparently they are transi

Hi Ola! I have both an XHdata 808 and a Skywave SSB radio, but not the newest one. They are both good radios and if you couple to a 20" PK loop or 4" FSL, they work very well and you will not notice a

I have a couple of ferrite probes that CCrane sells and that they also include with their standalone Twin Coil loop. That probe works pretty good as a pickup for my FSL's. It still needs an additional

I have worked with Guy on that design and on some of the tests to use an SDR or communications receiver with an FSL. Also, I had Andy of Wellbrook make me and Guy a special 72:1 winding FLG100LN anten

Hi Nick and all! I may be able to shed some light on the radio problem. Here In Grants Pass, OR I have two HP MW stations, 10KW and 5KW, just 2+ miles away on a river bottom. During the day and someti

Hi Gary, great comparison! To me the D-808 wins. I think the Skywave has a bit 'sharper' sound, but there is more noise getting thru the filter and in certain types of fading, the Skywave has an almos

Thanks Jay! I don't think I ever used DeOxit without a 91-99% wash afterward because of residue. However, it seemed that DeOxit might do a better job of removing oxidation if used first. The alcohol w

As far as expensive, yes DeOxit isn't cheap, but then it doesn't look like you need to buy a new capacitor at $20-$60 either and can refresh existing ones multiple times, instead of replacing. Alcohol

Hi Steve and all! I first tried DeOxit D5, with a spray alcohol rinse afterwards and lastly spray air to dry off the residue. I have also tried spray alcohol by itself, which seemed to work fine by to

DeOxit is not cheap here either! We use it here mostly for scratchy pots, with the F5 formula having more lubricant compared to the D5 formula. They both remove corrosion and protect the contact surfa

Gary and Steve, I had noticed a difference in older vs newer Oren caps also, although I saw no physical difference between them. I tried something on the 'older' ones that seems to work to freshen the

THE RADIO HAS BEEN SOLD. Thanks for looking! Hi all, I have an essentially new 7600GR for sale. I have used it very little. There is no box but the case, manual and windup antenna come with it. I am a

Hey Art! This is Dave Aichelman N7NZH formerly of 'The Villages' across from you in Dewey! We met just before moving up to Grants Pass, Oregon. Knew you liked MW DX from the AM DX group down there, bu

At Rockworks on the Oregon coast, the rock cliffs and metal mesh behind the cliff edge do act like a reflector of TP signals and somewhat of a shield to domestic noise. If the cliff areas were in prot

This is probably a question for Gary. I am trying to get a feel for how much better a 12"-15" FSL is compared to my 4 1/4: and 7" FSL's. I have used your comparative formula, but was wondering what I

Hi Michael, I have a 7" and 4 1/2" FSL that cover MW through 2Mhz + frequency. I don't have a 160M antenna to compare it with, but they seem to work well. If you wind your FSL coils so that 530Khz is

Yeah Bob, I tried to use the Yahoo email address you had a few years ago when I lived in Prescott Valley. We will be visiting the area in early May. Apparently that email address is not working anymor

By the way,, my FSL uses 200 mm rods and 1164 Lutz Dave

Hi Gary and all! I am lucky enough to have a large field behind me where I can test different antenna designs and compare ones that I have. I have run this series of tests several times and compared t

Hi Gary, On your 4 15" and 17" diameter FSL's, what length rods are you using. I was going to use your magic formula to figure out how much more signal they put out than my 6.5" X 200mm FSL (1300 rati
