    Best transciever I’ve got

    It amazes me that out of 5 hf radios, the best sounding radio I own is in my atlas 210. It is more sensitive and quieter that any others. The noise blanker actually works. Just the noise floor is much quieter than the others just idling. Blows me away considering the lack of crap packed in the...

    Triangle horz delta loop

    For fun and out of sheer boredom I strung up about 280 ft of wire in a triangle suspended about 20’ off the ground and threw a 4:1 balun at the north point for a feed. Trimmed it close enough and I’ll try it out tonight. If I like it I might consider doing a bigger loop for 160 I dunno

    Ofcd vs fan dipole. Opinions?

    I’ve been running a 80-10 off center fed dipole with the feed point at 45’ for a few years. I’ve been thinking of switching to a fan dipole. The ocfd is fine just wondering if a fan would be better. Any opinions on a difference between the two? Is one better than the other?

    Explain the differences in moving 2ft

    Imagine you’re driving down the road in your local backwoods farmland. Radios on windows are down and you’re enjoying the drive. You are on blacktop highway and other than a fence beside the road it’s open and clear of obstructions. You hear a station so you get the idea you’ll hit him up. His...

    Tower as antenna

    When I set up my tower I didn’t want to dig it in the ground so I could move it if I wanted to. So I used a plastic 55gal drum and poured in 5 bags of quiccrete. It’s anchored to the eave of the house. So it’s essentially isolated from the ground. It’s 55’ of tower I think to the top of the...

    Hustler btv5 revisited. Again

    I bought a silent keys shack and included was a hustler btv5 antenna. I tried it when I first got it and was not impressed. It’s been hanging around on the shed roof and I thought maybe I didn’t give it a fair shake. So I put it up again today. This time i thought I’d follow all the...

    Two questions. Is there a ground mounted. 10/11 meter vertical? I have a btv5 that I can’t stand for various reasons. And 2, if there is, how’s it preform

    Adding more ground elements to a ground plane

    If you took a ground plane such as a clr2 that has 3 ground radials and strung bare thin copper wire between them spaced out say every 5 inches,making a web what would that do? Would it increase preformance at all?

    Storm got it

    Storm got my ground plane. It’s not damaged it’s just lying over limp. Anyway, I’ve been thinking about fixing it. Then about replacing it. Then about just redoing everything antenna wise. So here’s my question. All things equal, some ground, same tip height on and on, all the same, is there...

    Diodes inline with antenna?

    Playing around I put two diodes inline with my antenna before the receiver. Attenuated the signal. But seemed like it did better than the rf gain with the signal to noise ratio. Is it? Or did I just imagine that it did? Or is it just an atrenuator?

    Grant xl noise blanker design

    I think I'd like to build a noise blanker like the one in the old grant xl radios. Does anyone have a good idea of figuring out the circuit? I suppose the schematic would be a place to start.

    Rm Italy low pass filter works

    I bought a rmitaly 27/586 filter looking to fix some issues. And it worked. 20m does not bleed over the surround sound anymore. The swr on all the bands have been improved and the auto atu does not have to tune near as much on my off center dipole. So the common mode currents have been handled.

    Poor ft847 receive 10m repair

    I’ve been fooling with a yaesu that’s been giving me fits over the receive sensitivity. It only affected the 10, 12, 17 bands. It still had rx but unless I ran the preamp it was super low. Figured I had blown it. Instead of looking into it I felt super lazy because I figured it was all smd...

    we have both fo these radios. both work well, however, no matter if you use the built in speaker or an external speaker they dont sound all that great on ssb. it almost sounds like theres a dsp running or the filter isnt wide enough. anyone else notice this? is there a cure? biggest downfall of...
