A station that is in a remote area but within easy low-power reach of one or even better two population centers can get fewer QSO's but most of them are 3-, 4-, and 5- pointers (and he may get a 1.5 multiplier on every Q if he was low power himself or a 3x multiplier if he was QRP.)

Re: Topband: 9 kHz heterodyne BCI
Lee is correct, I have had numerous times signals every 10KHZ across 160 all the way to 80 meters, the loudest being on 1810KHZ at times. The culprit turned out to be a station on 1540KHZ. the second harmonic 3080 was mixing with a station on 1270khz, ended up 3080-1270 = 1810KHZ. strange mixing problems, but there were 4 stations using the same antenna, all running 5KW. The combiner had corroded connections and bad grounds, it was finally repaired by a engineer who maintains all of the stations. This was located on Oahu which is over 40 miles across the water. So finding this stuff can take some creative thinking. I have also had mixing problems with iron wire fence on one side of my property that is corroded and making diodes, when the wind would blow it would rectify AM broadcast signals that were very strong and cause a wide band hash on 160. Even here at a extremely low noise location, no neighbors, utilities underground, etc, there is a constant battle on 160 to keep down all noise problems. It seems new ones pop up from season to season. 73 Merv K9FD/KH6 Greetings Bob, Having BC intermod on 160 meters has been a problem for a many years. It generally occurs from 2 or more of your 9KHz spaced BC signals mixing together and coming out on their spacings on 160 Meters. Mixing is the key word here and will be the key if you find the source. Mixing can occur right at the BC transmitter location from other signals coming back down the BC station antenna and mixing in their power amp. Mixing can occur in many different places between you and the BC stations. This can occur where there are fairly long conductors joined with a lousy rusted or corroded connections. This can be a line of fencing or guy wires on a power pole or many many other places where two things come together with a less than perfect connection. Mixing can occur in your own antenna if there are any bad connections or unwanted things touching the antenna. It can occur in a tower with bad joint connections. Mixing can occur in your feedline if you have bad splices or bad connector installation. Mixing can occur in a Preamp commonly used with receiving antennas. Disconnect it to see what happens. And mixing can occur in your own radio if BC signals are quite large. You were using a K3 so I suspect the mixing may not be in your radio. You can work back from the radio looking for potential problems. If you use a preamp you can eliminate it and check the levels of BCI left. If the bci is caused by the preamp the BCI should be reduced by more dB than the gain was reduced. Look around to see if there are any potential items such as a rain gutter or wire fence near your RX antenna Sometimes a portable radio can help locate the source if it is local by sniffing around any metal items in the area. Perhaps you could use a mobile radio to expand your range. Check to see how close your radio stations are to your antenna farm. Really close can easily mean overload of your system. Use a BC radio connected to your RX antenna and try to get some idea of the strength of the BC stations so you know what you are working with. Good luck, sometimes this is very difficult to find. Lee K7TJR Hi we just got QRV on 160 right before the SP and noticed AM BCI at 1800 kHz and every 9 kHZ up from there. Since 9 kHz is the BC channel spacing here I suspect two adjacent stations are mixing. Somehow somewhere. Maybe here in my station, one of the BC stations or somewhere else? Unfortunately our new HiZ 4/8 array was rendered inop before we could finish it due to rodents chewing away sections of the feedlines. We rigged up 2 2-way one wave Beverages and these heterodynes were the same strength from all 4 directions on them. Opening our tx vertical had no effect. Anyone know the likely cause/cure for these observations?

Topband: SP conditions from super-station
W3LPL is the only station I know of that has worked a major DX test accomplishing five-band DXCC 160m through 15. Frank has an exceptional station for 160m. N3QE, an excellent op, operated W3LPL for the Stew Perry, with this in his soapbox: -- Very little DX. I worked one DL, one S5, and one OK. Before EU sunrise I worked KH6LC and KH6AT just minutes apart from each other. No KL7 heard. The EU sunrise enhancement was confined solely to a little cluster of G/GM/EI and a PA who called in probably after his sunrise. -- If he couldn't get it from there, very little chance for the rest of us to work a lot of DX. I think that the real winners in this TBDC will be those CA stations who could work dozens and dozens of 12 pointers in that neat 03Z-ish opening, that must have been that quiet not-quite-dark period for left coast where they could hear very well. 73, Guy _ Topband Reflector Archives - http://www.contesting.com/_topband

The band isn't really open solidly on the left coast until around 0300Z or maybe even later like 0400Z or 0500Z. Then the trick is to then work as many stations as possible before the east coast QRT's for the night. I gave up at 0800Z because the band was worked out here and didn't get back on until 1100Z. The band was again worked out by 1300Z. I was happy to work dozens of 12 pointers as you say. Rick N6RK _ Topband Reflector Archives - http://www.contesting.com/_topband

Re: Topband: Silver solder
Hi Jorge, Very high cost silver solder isn't needed for radial connections. Any mechanically and electrically secure connection that achieves and maintains about an ohm or less of connection resistance will have an undetectable affect on the the performance of your antenna (much less than 1 dB) compared to lossless radial connections .

Re: Topband: Silver solder
Jorge, You do not need or want a high silver content. It will be too brittle. What you should ask for is a solder that has high tensile strength, is ductile, and works well with copper or whatever your radials are. That will not be a high silver content. It will probably be less than 8% silver with high tin content. Higher temperature is supposedly good for resistance to lightning, although I never had a joint unsolder even when regular electronics 60/40 soldered. - Original Message - From: Jorge Diez CX6VM cx6vm.jo...@gmail.com To: Topband topband@contesting.com Sent: Tuesday, December 30, 2014 7:27 PM Subject: Topband: Silver solder Hello I read about using silver to solder wire radials to terminals This week I decided to ask sellers about silver solder and they offered me a 2% and 30% silver bars What we need for our use?

Re: Topband: Silver solder
2% is about what the lead-free electronic solders are (they are a tin/silver/copper alloy and are mostly tin). Don't bother with the 30%. My mechanical contractor uses this stuff to fix things he can't reach well enough to braze. It's not generally used for anything normal. Coincidentally I was just out soldering more radials last night. I use 18 gauge solid copper radial wire and a 1/2 copper pipe ring to tie them together. My original 29 radials were all soldered with lead-free electronic solder and they are all fine after 2-3 years. I didn't do anything to try to protect the soldered connections -- everything is fully exposed and lying on the ground. I added 31 more radials. I soldered some the same way, but I'm trying regular lead-free plumbing solder on the others. I am finding the plumbing flux to work better than the rosin-core solder (it wets the joints more evenly). I'm not sure what the exact alloy is for the plumbing solder. If you use the solder bars remember that you'll need separate flux and brushes to apply it. I like the water soluble flux -- it cleans up way easier. -Bill KB8WYP Sent from my iPad On Dec 30, 2014, at 7:28 PM, Jorge Diez CX6VM cx6vm.jo...@gmail.com wrote: Hello I read about using silver to solder wire radials to terminals This week I decided to ask sellers about silver solder and they offered me a 2% and 30% silver bars What we need for our use?

The difference in price is extremely high! Thanks, Jorge CX6VM/CW5W The key issue is the absence of lead rather than the presence of silver. What has traditionally worked is STA-BRITE solder (2% or 3% silver, balance tin) available at any welding supply shop. Now you can get lead free solder for plumbing use, which contains no silver. There are also lead free electronic (ROHS) solders. All of these have a higher melting point than 63/37 and cost more. The silver in the STA-BRITE is mainly to reduce the melting point, rather than to do anything special to the joint. They should all be fine outdoors, where lead solder rots in the moisture. A related issue: we were all lectured never to use acid core rosin solder on electronic work. Is it safe to use acid core plumbing flux for soldering radials, etc.?
