Equipment / Re: More Wire, Higher Wire, Longer Wire
« on: July 21, 2019, 0227 UTC »
the 6800 is odd in that it's whip works better than an external into the SO-239. The CRF-1 is just the opposite, whip is useless but on an external it really shines.

"Is it possible the 6800 has an attenuator on the external antenna plug?  My ICF-2010 goes deaf on MW if I plug the skywire into the plug."

Never considered that, it might be the case. I know that the later WA "Orange" version had a 20dB attenuator switch on the back which the earlier version did not. Perhaps giving users the option was one of the updates, though I've never heard of any reference about an external antenna attenuator on the original. The difference between external and whip is noticable on HF. I've never used the SO-239 for MW, just the internal ferrite.

The AOR-AR3030 operates from internal batteries as well but AA cells and they last only a half hour.

" :o Ouch, what's the point with that burn rate!?"

Good question! 


I'm kind of surprised that long wire doesn't cause problems on your portables.

"I have isolating transformers on both ends of the feedline and assume they aren't very efficient, introducing enough attenuation to prevent overloading.  The Tecsun does have problems with this antenna system sometimes."

Interesting discussion!
I enjoy older radios and particularly portables but more along the lines of tabletops that operate from internal batteries, they are better at handling larger wire antennas than the traditional small portable, and I enjoy old fashioned bandscanning with a tuning knob.
I have both the Sony ICF-6800W (not the WA "Orange") and CRF-1, the 6800 is odd in that it's whip works better than an external into the SO-239. The CRF-1 is just the opposite, whip is useless but on an external it really shines. The Kenwood R-300 and Bearcat DX-1000 use D cells as do the Sonys. I enjoy both especially below 2 MHz (I read that its best to use a preselector with the Bearcat but I find its still enjoyable without one). I've wanted to try Panasonic's RF-B600 and the Yaesu FRG-7 but haven't yet. You might want to give one of these a try if you find one at a good price just for fun and a change of pace. The AOR-AR3030 operates from internal batteries as well but AA cells and they last only a half hour.
I've used a T2FD in the past and highly recommend it, very low noise even in a suburban enviornment allows for weaker signals to be heard. That report about a 6' whip is something I read before, maybe proper matching is the key to the Apex 303WA-2 getting good reports.

It is fun using any radio that isn't expected to receive much but finding that you're listening to things completely unexpected with it. That's why I like my DX-1000, the bad reviews said to stay away but it's my favorite receiver (not best, just favorite).

A great receiver! I had one without the preselector (rarer than hen's teeth).  Unfortunately for me it wasn't designed for bandscanning which I love to do so I sold it, but otherwise no weaknesses.

Scott, those are inpressive LWBC catches. Can I ask your receiver/antenna setup?
Best I do here in FL is 171 Medi 1 and 252 Algeria semi-regularly. Once caught 216 Monaco as my only Euro.

Chris, I have the land to set up a 1240' true square sky loop and have a couple of questions.
Do you notice any directionality at all with regard to the balun placement, or does it seem truly omnidirectional?
Also, I have your Squid, what impedence would you expect this sky loop to be seeing?  With so many configurations of the wires on the Squid I know I can experiment but what would you recommend as a starting point?

Equipment / Re: General Coverage Comms rxer down to 20KHz?
« on: January 17, 2019, 0133 UTC »
If you don't want to spend the big money on a Watkins Johnson and government/military receivers like that, and don't mind an older design, I've been using a Bearcat DX-1000 for years. It receives very well down to 10 kHz with excellent sensitivity below 2 MHz unlike most other consumer receivers. They can be found on eBay for around $100-150 because of some bad reviews (from SWLs) and I use it with a ferrite loopstick for finding those submarine signals down to 15 kHz with no problem.
Another, albeit more pricey, receiver is the Sony CRF-1. This one tunes and receives literally down to 0 kHz. They can be found occasionally but anywhere from $600 (which is what I paid for mine) to over $1000. For that much money, might as well save up for a WJ/Racal/Cubic.
