the FCC & your neighbors happy. I am thinking about 1 of these amps myself. I guess CCI at least gives you schematics for the LPFs. Hi Fil, For those under the FCC rules, building the CCI amp (or

Hi Jeffrey, Your main problem is neither connector on the 817 is a type N. The front is a BNC & the rear is a UHF (SO-239). No one I know of makes an elbow adapter from UHF (SO239) to BNC. You can

CCI offers the filters for each band

Yeah, and in more ways than one, perhaps (ease of transport, cost, ease of setup...) <g> = "grin" so wd be equivalent to "hi hi" or :-) I

Pull out the telescoping section all the way, then adjust the coil for resonance. Cortland various with the the ...

A 75 ohm BNC female pin may be permanently deformed if a thicker 50 ohm BNC is inserted into it. We have seen this happen with video connections at work. Cortland BNC's

VE3XJ and N1XTR -- Yes, I'm interested in more tries with this all, and it's been an educational discussion so far -- thanks to all here and on HFPack. (Haven't heard anything from the NVIS group

Hi John, They are unfiltered & require the addition of filters to keep the FCC & your neighbors happy. I am thinking about 1 of these amps myself. I guess CCI at least gives you schematics for the

Sorry for being away so long. I came down with something this week shortly after the experiment between John (KB1FPM) and I. John, I hope that viruses can't travel by radio waves 8-). I have been

John: My best recollection is the experiment that was undertaken by one of the authors (Fielder, I think) with a point-to-point communications in south-east Asia (Thailand, I think). The link was

good The 50 Ohm and 75 Ohm BNC connectors have the same pin diameter in the mating area, so they will interchange without any damage. The pin diameter of the 75 Ohm connector is the same

BE very careful with BNC's. There are 75 ohm as well as 50ohm BNC's out there. The difference is the center conductor. One is thicker than the other. In one configuration the connection will not be

I use a PL-259 to SO-239 elbow with a PL-259 to BNC female adaptor. It works fine. These are available from just about anyone who sells wire/cable. Not sure if RS has them but their connectors are

I am fairly new to the list and I am sure this has all been covered but if someone can take the time to e-mail me [email protected] will really appreciate it. What are the best lengths

Woops: BNC. Like on the front of the 817.

Karl, Thanks. I meant to say BNC, not "N" I left B and C off. I am describing my front BNC connection. I can't get the rubber ducky to connect to the BNC elbow I successfully put onto the front

Jeffrey, I have a box full of BNC adapters including male-to-male elbows, female-to-male elbows, barrel connectors...you get the idea. And I can tell you that often times one BNC does not match

I don't believe, Jeffrey, that "N" series connectors will work on the FT-817. The front panel connector is a BNC, and the rear connector is an SO-239 ("UHF" series). Karl K - W8TIF McKinney, Texas
