Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
Unfortunately the MFJ-16010 is configured as an L-network tuner and will have to be rewired to work as a series or parallel trap circuit. It also may not also have enough tuning range to go down to

Re: PL-390 FM DX
Phil and others, You mention on your site that your picks are the Sony SW7600GR for SSB radios and PL-380 or PL-390 for Silicon Labs DSP-based radios. I was thinking of a PL-660 but your write-up

Yes, the qsl jpg below from Graeme is the correctone,
such as I had in mind. I´m not sure whateffect the low-Z
ouput from the long-wire balun mighthave on its tuning sharpness,
however. Fig 2A

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
Just a note:
The circuit shown in fig 2B is incorrect. I think he meant the parallel circuit to be in series with the antenna lead, not in shunt configuration as shown.

The Sony T-615 Pulls in Another New Station Here
Good Day Everyone,
The trusty T-615 shined here this morning with another new station logging. What makes this one so special to me is that the little rig was able to null our semi-lcl 50,000 watt

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
The G3 is not well suited to an external antenna...my Wellbrook ALA330S overloads it badly even in teh daytime. My PL-660 handles it much better.

I imagine that Michael is referring to a simple parallel tuned circuit which is inserted in the antenna lead.

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
Thanks for the reply Michael. What type of trap circuit do you mean? I do have a MFJ Antenna Tuner in series with the 80 Ft Balun Antenna and Zim just pointed out it needs to be grounded which it

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
Hi Jerry,
Yes, judging by the pix at http://www.mods.dk/picture.php?brandid=15&model=mfj-16010
the MFJ-16010 has coax connectors for both in and out.
The earth wire should connect to the case.

Thanks Zim, and great info on the 16010.I do have an earth ground wire connection to the cold water meter in the basement where the MFJ 16010 Antenna Tuner is located but its not connected!! Great

The MFJ 16010 is configured as a low-pass filter, so it probably won't eliminate BC overload.
Do you have a good earth ??? An ATU can't

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
Antenna Jumper around the Radio instead of clipping it to the Aerial, then it wasn't so bad.
- As Jay said, use the antenna input, that is what it is there for. Connection direct to the whip is far

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
I would suggest using the antenna input on the radio rather than clipping it to the whip. The whip antenna is typically amplified, which is obviously not what you want here.
It doesn't appear the G3

Re: Reception on Grundig G3 NOT Amazingly Improved with new 80 Ft Longwire Antenna
Not surprising, Jerry : total overload! Take care not to fry the front-end.
You could try a trap circuit between the longwire and the receiver
to null out the 680kHz local to some degree.

Well after DXing late last night I am dissappointed. The Antenna seems to be way too strong!! One local 50.000 watt station here was overriding ALL the Shortwave Bands. AM reception wasn't as bad, in

Re: Sony SRF-T615 noise-cut
I'm no tech expert on radios, but I believe it would be considered an attenuator not an RF modifier.
