RE: [Elecraft] K1 internal signal generator?
-Original Message- ... The K1 receiver operates on lower sideband for all bands. If you have properly set your CW offset to, say, 600 Hz, then your transmitter frequency will be 0.6 kHz lower than your receiver frequency. Most hams want the frequency display to show transmitter frequency rather than receiver frequency. In that case, when you are zero-beat with a signal at, say, 6999.3 kHz, you'd want the LCD display to show 6999.3 - 0.6 = 6998.7 kHz, which will be the frequency transmitted when key-down. ... The display frequency indicated above is not quite correct. When zero-beat with a signal (meaning to hear the signal at the sidetone pitch), the receiver display should indicate the frequency of the carrier. Yes it is true that under these conditions, the actual receiver frequency is offset by 600 Hz, but the frequency display should show 6999.3 (the center of the receiver passband will be 6999.9 kHz) Think of it this way - the receiver should always display the carrier frequency that will be transmitted - and that works for both CW and SSB. 73, Don W3FPR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] N fittings
Bob, G3VVT wrote: Yes, it does work. However there is a downside in that the silicon grease prevents most kinds of tape adhesive sticking to the connector for providing external weather proofing. The only exeption to this may be the greased fabric tape (Denso tape) used in waterproofing connectors on comms towers though have never tried with this. Attempts afterwards to remove excess silicon grease that reaches the outside of the connector and so allow plastic or self amalgamating rubber tape to stick were not successful. Hi Bob, When I have used Vaseline, only because there is usually some in the house, I coat the mating threads and almost fill up the space between the gasket and the cable end of the connector (N type) before inserting the nut. Some goo oozes out which I wipe off. I then cover with Scotch Super 33+ tape, starting the tape winding 4 to 6 inches along the cable from the connector. Each turn covers about 3/4 of the previous turn, and I keep going untill 4 to 6 inches along the cable from the other mating connector. I then reverse direction and keep winding back to the starting point. Pretty crude, but the shell of tape and any goo in the connector area plus the goo in the connector has so far kept the weather out. I was at one time concerned that any Vaseline that might short circuit or disturb the RF path could cause problems, but none have been detected, and no sign of gasket problems. Will be in touch about 4m off-list. 73, Geoff GM4ESD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] N fittings
I have not knowingly used silicone grease on coax connectors, but would discourage liberal use of the stuff. Silicone grease has its place, but if I were using it, I would only suggest a little dab on the center conductor. The stuff migrates everywhere and few things will stick to it, so one would have trouble putting any additional tape or coax seal over the top of things. 73, Don W3FPR -Original Message- In a message dated 15/02/05 14:33:15 GMT Standard Time, [EMAIL PROTECTED] writes: Question... has anyone ever heard of or used pure silicone grease in coax connectors to protect against moisture and corrosion? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Waterproofing coax connectors (Was: N Fittings)
I've tried different methods of waterproofing outdoor coax connectors for years, and here is my experience, for what it's worth: 1) Vinyl electrical tape by itself -- the cheap kinds unwrap themselves. The expensive Scotch brand (and possibly others) will do a good job, but you need to follow their instructions, use the proper amount of tension, and do it carefully (sometimes hard to do while standing on a ladder, etc.). 2) Vinyl electrical tape plus Liquid Electrical Tape -- I have just recently started using this method, so I don't have long term experience. But it seems to work well. You use any kind of vinyl tape, even the cheap junk, and then coat it with the liquid tape product. The liquid contains a solvent that softens the vinyl tape, and it seems to seal very well. It is easy to remove by slitting it with a knife. So far, no problems. 3) Coax Seal -- Does a good job and is easy to use. I have had connections seald for years which have stayed dry. A little hard to clean up when you take the connection apart. 4) Heat-shrink tubing -- Don't use it Here in Fresno we have lots of sunlight. Apparently the shrink tubing is attacked by UV, whereupon it splits, leaving you with no protection. I know some commercially made cables come with it, and maybe there's a kind that's UV proof, but I don't trust it. 5) Cushcraft-type boots -- I had one of these split after a few years in the sun. Again, there may be various types, but I don't trust them either. 6) Self-vulcanizing rubber tape -- I've never been able to apply it properly, but looks like it would work well (although I don't know how it would respond to UV). Tends to want to stick to itself, etc. Everything is harder when you are on a roof or tower. Just a word about what happens when you DON'T waterproof your connectors: water will corrode the joints in the connector, but worse, it will move into the coax braid by capillary action. It will invade the entire piece of coax, corrode the braid, and render it very, very lossy. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] N fittings
I would stay away of any type of silicone because some silicones if applied directly on the coax will harden the outer insulation and cause cracks if they are bent. Also silicone does not have more than 5 years of ageing before it should be removed and redone. The cushcraft boots will eventally go into a chewing gum like state after a couple of years. I would recommend a good electrical tape with selfvulcing tape over that again.

Re: [Elecraft] Waterproofing coax connectors (Was: N Fittings)
Adding to Vic's previous comments... from my own experiences... At 10:54 AM 2/15/05, Vic Rosenthal wrote: I've tried different methods of waterproofing outdoor coax connectors for years, and here is my experience, for what it's worth: 3) Coax Seal -- Does a good job and is easy to use. I have had connections sealed for years which have stayed dry. A little hard to clean up when you take the connection apart. I've found that Coax-Seal works best (for me), if I use it OVER an initial wrap of good quality plastic tape (Scotch #33 or #88), and then OVER-WRAP it with another wrap of good quality plastic tape. UV will kill coax-seal if it's not protected from UV, and coax-seal is simply MISERABLE to remove from just about ANY coax connector if you install it directly onto the connector (without an inner wrapping). For the past 5 years, I've switched to self-vulcanizing (silicone) tape... see below. 6) Self-vulcanizing rubber tape -- I've never been able to apply it properly, but looks like it would work well (although I don't know how it would respond to UV). Tends to want to stick to itself, etc. Everything is harder when you are on a roof or tower. The self-vulcanizing tape I use was purchased at Dayton over 3-4 years, from an amateur radio club in Minnesota... it is a gray silicone tape and VERY flexible and stretchy (almost a 2:1 stretch factor). I apply this tape directly to the coax connection, overlapping it about 50%. I then follow with a final overwrap of 3M #33 or #88 tape. It has, so far, kept every(!) drop of moisture from the connectors it's protected. There was no name on the rolls of tape, but I'm told that they were donated to the radio club by a 'very large' tape manufacturing company which has three similar letters in its name, and this is also located in MN. Hmmm... apparently the tape failed one or more of their QC tests, but was still good enough for most uses, just not those for which the company was willing to have its name shown on the product. Self-vulcanizing rubber tapes I've seen should work just as well. If they appear to want to really stick TO the coax connector (such as Coax-seal does), you might want to first apply a protective don't stick to me wrap of plastic tape (even the cheap stuff will work here), and then apply the self-vulcanizing rubber tape, and finally a UV protective layer of good quality plastic tape. Finally, the question of how to 'terminate' a taped wrap... some just pull it tight and then yank on the tape until it breaks, wrapping the loose end around the already-taped connection. I've found, from experience, AND from numerous suggestions from those who have done a LOT more if that I, that when terminating a wrapped connection, it is best to pullout a loose end of maybe 3-4, CUT it off, and allow it to hang free for a short period of time, to allow any previous stretch to be recovered by the loose end. Once it has returned to its UNstretched length, wrap it snuggly around the taped joint, using the larger diameter of the taped joint if possible and WITHOUT much pulling on tape as you wrap it. This allows the tape to seal against itself well, but having not been stretched, it won't want to unstretch later on when the sun comes out and heats up the taped joint, softening the adhesive. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Waterproofing coax connectors (Was: N Fittings)
Tom is very correct. In 3M presentations on their specialty tape products, they emphasized NOT yanking off the end of any tape; but to unroll as Tom says, and let it relax then CUT the tape from the roll. That way, you will not have loose ends hanging off the installation after a few weeks. This is true of any tape with stretch. 3M has a broad line of self amalgamating tapes. They are used extensively in the electric utility trade; so met a local lineman, or check with electrical wholesale houses in your vicinity. If ever you can get a 3M rep. to give a local club a presentation, they are fond of bringing samples to give out. 73, Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] N fittings
My understanding of the place to place silicon grease is NOT upon the outside of the connector, but rather in the interface between male and female connectors. The idea is to exclude moisture pooling on the insulator between the center pin and the outer shell conductor. However, if you over wrap a coax connector with a good quality electrical vinyl tape, and cut the end, rather than stretching it to break; you can then overwrap with coax seal, Dux Seal, or self amalgamating tape lapped 50 percent, and have a long lasting but recoverable seal. N connectors by their very construction do not typically need the addition of silicone grease. They have adequate fine threads and tight fitting interfaces between plug and receptacle. I prefer NOT to seal with silicone grease to enable inspection of the connectors every year. -Stuart K5KVH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

The idea is to exclude moisture pooling on the insulator between the center pin and the outer shell conductor. -- Silicon grease would only be placed on the inside of the connector, but enevitably some can be squeezed out, making it's way to the outside and in the process is transferred to your hands. Once that happens there is no way in the world that most tape adhesives or self amalgamating/self vulcanising tape would adhere to the connector or even itself for that matter. It only takes an exceeding small amount and seems impossible to remove by normal cleaning. This would be why Don, W3FPR was wisely advising caution on the amount of silicon grease used. With self amalgamating tape one has to be careful as some types are said to be attacked by UV, though did use one brand of it in waterproofing CATV connectors in the UK for a number of years without any problems. Applied the self amalgamating tape directly over the connector, then applied a layer of heavy duty plastic tape over the top for mechanical strength and protection. What one uses depends where you live and what the exposure to UV levels are. What could apply in latitudes further away from the equator would not be applicable in hotter climates. I lived for many years in the Middle East and most types of self amalgamating tape would probably not be usable there due to extremely high levels of UV. Normal plastic tape had a rather short life and such things one would use normally in cooler climates such as polypropylene rope and plastic cable ties failed very quickly. The rope was turned to dust in the space of little more than a year and plastic cable ties went brittle and snapped. Never managed to source carbon loaded cable ties, though nylon TB Tywraps did last a few more years longer. The only sealant I have seen that seems to stand most situations is the fabric/heavy grease type of tape. This is known commonly as Denso tape in the UK and was pretty well standard on professional telecom installations for external connector sealing. Have seen a similar type used in the Middle East for the same type of installation, so presume it must be resistant to the effects of UV. This tape or a very similar type is also used on small bore natural gas lines for joint sealing and protection, so this could be another source of supply. Rather messy to use, though does give extremely good protection to external connectors over many years.
