Dear all. There's been some discussion about filters etc recently which reminded me of a question I wanted to ask the group... What receivers/tranceivers work well on LF? and possibly.. What receiver

However, I recently asked if anyone knew of a Level Meter D2155 made by Siemens that I recently aquired. I got no response so I assume that no one knows about it.......... Peter (and anyone else int

From HB9ASB, JN36PT Another one for the list: ICOM IC765: on 136 kHz as good as commercial LF receivers after removing the internal LF attenuator! Very good selection with cascaded 250 Hz filters. Ca
de DK1AG: I am evaluationg, if I am to design a front-end crystal filter with a bandwidth just equal to the width of the 136 kHz LF band. It will be a four-pole filter with an ultimate attenuation of
Hello Dave Thank you for responding to my enquiry. I was quite supprised to get the response from ZL - I expected the response to come from just across the water in DL. I can scan the 1988 Siemens ca
Hello Bernd, someone here already used an x-tal filter at the input of RX as far as I remember. I do not know his experiencies. Anyway, I would be thankful for such a filter, but shifted by 10 MHz, t
Hallo to You all from DJ2LF About receivers/transceivers for lf: I use the the IC729 (=IC728+6m) with 500Hz filter. I think it`s rather good for big antenna, not for loops. My location in a small vil
Most receivers around are adequate for 136 khz reception of radio amateur signals. Basically all that is required is a narrow IF filter especially at the the last IF normally 455 khz to avoid adjacen
Greetings, A couple of months ago the "which receiver?" thing came up over here, too. The attached below is a message I sent one of the guys (he was toying with getting a TS-440S, with which he is re
I am compiling a list of receivers and transceivers suitable for 136kHz. I know most of the older radios already but does anyone use a radio made in, say, the last five years that they use sucessfull
Mike, I'm using a Kenwood TS440. Sensitivity is very good at 136kHz. A small loop (1x1m) can be used without pre-amp, if I am using the TX antenna for receiving I need at least 30dB attenuation befor
Hi Mike AOL 7030 But as this was at the recommendation of Alan G3NYK he would be the best one to comment and his opinions would do for me as well. All in all I think it's a hell of a Rx at any freq i
Tentec RX-320 with AMRAD mod CUBIC R3030 and R3090 a bit older than 5 years but a very good receiver down to at least 16KHz. see http://www.amrad.org/projects/lf/rx/index.htm <x-tab> </x-tab><x-tab>
I run my TS 440 on 1750 meters and noticed it has similar sensitivity as my HP 3586C Selective Level Meter. Good to hear another person using it even lower and still having good sensitivity. Mike WE0
My HF-225 is sufficently sensitive at 136 kHz to be operated on its own without preamps and its 200 Hz CW filter is good enough. Have never noticed intermods etc even putting a big antenna on it. Hav
Hello Jay, Hello all, i was just looking for more information about the Harris RF-590 and found this page : http://www3.ctktv.ne.jp/~tadashi/RF590/RF590.PDF Its a Block Diagam... greetings Arthur Har
I used in the past the TS-850 which is an excellent receivers in the LF range. What I am using now is the JRC NRD-525, a very good receiver indeed on any band. It is factory fitted with a TCXO with a
