Re: Topband: PSK31 etc

What are recommended frequencies for PSK31 and FT8 (and others if applicable) on 160m? I don't know of digital activity on 160M other than WSJT modes. It's mostly FT8 and WSPR, very occasionally FST4 and FT4. Default frequencies are in WSJT-X. Study the manual to activate them. 73, Jim K9YC

Topband: Measurements before and after connecting radials

I plan to install a "significant" number of additional radials in my lawn to connect eventually to my shunt-fed tower on 160M.  Currently I have 7 18AWG radials connected to the tower and plan to add more from two reels of 500M long mil surplus twisted pair wire I bought in 2020.  I'll keep

Re: Topband: PSK31 etc

For FT8, 1840 USB has lots of activity every night, domestic and DX. DXpeditions sometimes operate on 1836 USB or other frequencies to avoid QRM -Original Message- From: Topband [mailto:topband-bounces+lloydberg=tds@contesting.com] On Behalf Of Michael Rutkaus Sent: Monday, February

Re: Topband: Series LC to notch AM broadcast ?

Hi Jim, When I lived in Melbourne Florida, I had an 920 KHz AM station with a four tower array a short distance from my house (I forget the exact distance, it was probably on order of 1/2 mile). The daytime pattern beamed toward my house with a TPO of 5KW. At the time I was using a Ten-Tec

Re: Topband: RG6 coax

Hello,  I'm using an RG-6 (F660BVF) gel filled cable to connect the shack and remote beverage switch. This  cable can be directly buried in the ground (no need to use a pipe or slive) and remains as good as new for many years. Several times this cable was broken by metal seekers with shovels.

Topband: RG6 coax

Jeff, I have been using Satellite TV RG6 for years with my different RX antenna schemes. It has a solid copper center conductor and is swept to 3 GHz not that it matters for low band reception. I also have been using compression connectors which are far better than the crimps I used well

Re: Topband: TV coax + F-connectors

Good luck with that voltage breakdown rating for foam RG6 running high power through it and other than a flat line. As to the milliwatt loss on transmit, okay FB but on rx with microvolts, I'm already deaf and don't need for it to be any worse than it is. 73 Rob K5UJ _ Searchable
