![]() ------------------------------- I own a McKay Dymek DA5 and have compared it in a side by side test to the Palomar. Both do a credible job. However from research for a friend I think the Kiwa loop will perform much better. See the link at: http://www.kiwa.com/pktloop.html See the reviews at:http://www.kiwa.com/review.html I would love to try one of these heads up against my DA5, but based on these reviews and some others that I have read, I think the Kiwa is much better. A friend moved to central KA and wanted to listen to WHAS in Lossyville KY. He was going to buy one when he found WHAS is available via the web. Terry I own both the KIWA and a McKay/Dymek DA-7 (which is the same as the DA-5, except that it also covers longwave), and I can attest that the KIWA is eminently superior. --Guy Thurston, OR |

You might also consider the AOR LA320. Universal has them in closeout. I have had excellent luck with this one. It has 4 interchangeable loops, which cover LW, MW. 1.6 MHZ, 5-15 MHZ.

I had always thought it's main claim to fame was a longer feritte rod. TheDA5 diagram is very simple. It would be nice if it is easy to modify the DA5 to co er LF as well. Terry |

Terry:
The only diagram I have is the one that came in the "manual" (4 pages) and is labeled, "DA-5". There is no separate diagram for the DA-7. There is no difference in the length of the ferrite rods between the DA-5 and the DA-7. --Guy On 8/4/05 5:31 AM, in article , " wrote: Guy Kudlemyer I own both the KIWA and a McKay/Dymek DA-7 (which is the same as the DA-5, except that it also covers longwave), and I can attest that the KIWA is eminently superior. --Guy Thurston, OR ----------------------- Do you have a diagram of the DA7?

Thanks.
Is the band change switch on the loop or on the tuning unit. If it is on the loop then they are adding more turns, if it is on the tuner, then they are adding more capacitance. I don't know if you have ever had the loop open, but it has very few turns. Much less then one would expect on a MW feritte rod antenna. Terry |

Just what do they mean by Active? (hey,I am dumb) Does it mean it is
Active because they use a battery and the battery "Activates" it? cuhulin |

For example the AmRad active antenna uses a special FET (Field Effect Transistor) and is "as effective" as a ~100' long wire. For low frequencies, like a 60KHz signal, even a 100' antenna is short. The AmRad, DA100-E, "North County" and even the "Tiny Tenna" all use transistors to convert a small 36" or so, wire into a usefull antenna. The Tiny Tenna is the simplest, but even it will do a decent job far from any MW (AM 540~1600KHz). Loops can be passive or have amplifiers, and those with amplifiers are termed active. For RF reception from 500KHz through ~30MHz I prefer the common ~100' wire antenna. For MW DX work a loop is hard to beat. For LF work, 500KHz and lower, an active antenna is the only practical way to go. Terry |

Awwwww, forget them Tiny Tunna,s (Oooops,Tiny Tenna's) I bought one of
them from that fool about eight years ago.It arrived here dead on arrival,I will never buy anything from that mf (Massey Ferguson) b.....d ever again.Thanks anyway for the explaination about active antennas. cuhulin |

Terry:
The band change switch is on the loop. The knob on the front of the unit has MW freq's listed on one side, and LW freq's listed on the other, 180 degrees apart. The LW runs from just below 150 Khz to just over 300 Khz. The MW seems to tune all the way down to 510, and up to about 1630. --Guy On 8/4/05 2:42 PM, in article , " wrote: Thanks.

That means they are switching more windings for LF. I bet they use the exact same electronics in the tuner and all the magic is in the loop. I further bet that I can get at least 3 bands, 100~300, 300~500 and the stock MW. It would be nice to see if it will work down to 60KHz for WWVB all the way up to 1.8MHz or above. Since I have a spare feritte rod, I will have to "duplicate" the rod part and see what I can see. I won't get around to this for a few weeks or longer, but if it works I will post the number of turns I use and the results I get. Terry |
