Re: Topband: Wednesday CW DX Activity Night

2022-01-18 Thread David Olean
Hello Roger Well, Monday night had very good conditions. There were hardly any stations on, but those that were  sounded great. I worked a DL station who was QRP, and he was peaking at 559. Then ON4WW called me and said he was running 1 watt. He was 559 also! He was over S9 when he ran his KW!

I gather there's been a lot QRN across North America over the past week . . . But from QSOs and RBN reports it seems that conditions on 160 have improved the last few days. So hopefully we will see a lot more QSOs tomorrow night ! 73 Roger G3YRO _ Searchable Archives: http:/

Topband: Preamp Placement?

2022-01-18 Thread Roger Kennedy
I use a 6ft diameter 4-turn loop as my 160m DX Receive antenna . . . If it's only used on receive, you can easily make a tiny transformer between the Loop and the coax . . . so Common Mode pickup wouldn't be a problem. I have a pre-amp in the shack on the Loop . . . that's set so that local sig

My loop has an amp located at the loop but the sig at the radio was waaay down.I added a DXE broadband amp at the operating desk to get the sigs back to parity with my vertical.An internal preamp in a modern radio might do the trick but even though I have a TS-890 I have not tried the preamp wi

Haven't seen much in the way of public replies to this, so hope that you've got some private ones. For a small mag loop, I'd use the preamp at the loop, especially if your feed line is coax. 73 Nick VE7DXR At 15:09 2022-01-16, Chris Maness wrote: Do preamps need to be close to electric
