Scott, I didn’t have “RF fratracide” problems until I started using the 400 watt TE Systems amplifiers. My stack allowed about 18” between Yagis. I toasted the front end of an Elecraft 222

I have wondered the same thing. On my antenna stack, which is not even that closely spaced, I have played it safe and disconnected the coax on the non-transmitting antennas. So far. I had a bad

That’s a good idea (amps) but I’m going to be totally barefoot. I’m thinking I’ll just keep it down to 10 watts or so, and play it by ear. -TA On Jun 1, 2019, at 9:57 PM, Keith Morehouse

I don't know the exact answer, but one thing you can do to protect yourself if you're using any kind of amplifier on the three ports is to T/R all the amps together, even though you're only using one

I have a brand-new IC-9700 that I’m itching to try out in the ARRL contest next weekend. That rig has 3 separate antenna connections, one for each of its bands (144-432-1296). I have all the

That’s so cool! Im looking for a way to help you in June. Unfortunately most projects are half done and Im distracted by microwave stuff. I have good capability on 6, 2, and 1.25 but thats

Bill, I've been dark-testing the old DEMI you loaned me for so long I figured I should just buy one of my own to continue that test. Now that I can get a confirmed 900+ watts out of my TV transmitter

Well done! Bill W7QQ

I decided to buy one of LZ5HP's 900 MHz transveters after being reminded by an earlier message on the reflector. Here's the current info on P & D. Note that the EU-USD exchange rate today is close

Hi Alden, There are two questions here: 1) What's better for the rover, fixed antenna pointing or independent antenna rotation, usually via remote controller rotor? and 2) Is there a better material

The majority of rovers use this system - it is mechanically easier and doesn't require either a 12V DC rotor system or a DC/AC inverter to run a classic rotor system. Back east, height above ground

Maybe one of the newer version M2 5 el might work. Take off the "far end" and maybe you'll have a 4 element. You'll need to look and see where the boom comes apart. The original 6M5 I have looses 2

This antenna support structure, made of pvc tubing, was on KF8QL’s vehicle at the Hamvention last week. Antennas range from 144 MHz to 3.4 GHz. My question to you is “What are the pros and cons of

Hi Bruce, The M^2 6M5 is my favorite (not the 6M5X). It’s 15 feet long but weighs only 11.5 lbs. all elements except the driven element can be folded against the boom for transport/storage. Wing

I’m looking for recommendations for a good portable 6-meter yagi. Good performer, 3 or 4 elements, preferably direct feed, easy to transport (comes apart in only 4 or 5 pieces — boom plus

Bruce I think I saw a price of $1699 Mike

I'm hoping to have 6 through 432 operational again for the June contest. It all depends on whether I have the time and weather cndx to get the temp tower up. If I have full capability, I'd love to

From the Elecraft web site: “Due to possible price increases from our suppliers, we are unable to provide you with the price of the Elecraft K4 or K4D. We anticipate that the highest price tier

Thanks for sharing that info Bob.
