Thanks Marco 

For the enouragement and advice ! 

Yes we all would like to be on the sea shore . If there is some contest I will apply for some special permission and call sign too !

Then find a good spot on the sea shore . 

The Antenna is a vertical of 12m and top loading wire of 20m 

As suggested by Stefan I will tune it up for 630 with a bottom loading coil .

Also will make a loops as you and John suggest to combat the noise .

I also have an NRD 72 , NRD 75 and an NRD 535 will have do some repair works and get them working on 137 and 475 Khz band . 

I do hope to be able to hear your sigs soon 

Best regards to all

Hi Kumar,

Stefan already pointed out the main topics ;-)
I know other MF/LF operators are using TS590 both for RX or generator with suitable PA on LF and MF so you have already the first brick.
If you are coming from 160m activity you are already half way :-) - you wrote about small roof antenna for 160m is that a vertical or a dipole? As pointed out from Stefan a vertical could be retuned for MF/LF txing. Due to high noise both from city and geographic area again the suggestion of Stefan for a tuned RX loop is probably the best solution, but a try with a PA0RDT active antenna could be worth.

I guess we all would like to live close to the seaside :-)) this my dream too ;-) could share a lovely QTH for HAM radio and easy for scuba diving :-))

I will keep on still for some days transmitting on WSPR2 on 137 kHz then reverse to 475 kHz with my small beacon: I have all days reports within 3000km (EA8ARZ is my best DX) but my opinion is that there is lack of RX stations between 3 and 6000 km in some direction.

CU later,

Hi Kumar,

What is your locator? And the locator of the new QTH?

WSPR: Just have a look at http://wsprnet.org/drupal/wsprnet/map (Select MF and 24 hours) to see who is active. There are chances to pick up stations from VK but also from Europe. FR5DH is a real station and he managed regular decodes from Europe. This is a similar distance, also with a significant land path component. So you can do it too.
There are different RX antenna solutions of course. Your RX will have a low input impedance and maybe it is a bit deaf on this band (?). So a preamp can be helpful. If you want to avoid building one, you will need a large antenna. But if you are active on 160m then maybe you have a large vertical antenna. This can be tuned and resonated to the new band. It will help to prevent overloading the RX and gives you enough signal.
Or, build a tuned loop! This will also help to reduce QRN from uninteresting directions and some gain in the direction of interest.

What types of antenna will you have on the new QTH?

Hi Stefan and freinds 

Merry Xmas and a happy new year .

I am active on 160m meters with a TS590s and the IC7300 . 

The TS590s is probably good for 630M .

I am moving out of the city in a months time and  will have more place .

it would be good to start receiving first , will have to  build some LF antennas for receive .

I will try to leave the RX on WSPR mode each night , after local midnight ,

What are the chances of listening  ? who are the active stations in Asia ?

would also like to set up a remote RX in some rural low noise area . 

Thanks again 

Best regards 

Kumar

Hello Kumar and welcome!

What kind of help do you need? What is your rig at the moment? Some photos?
