Topband: JT-modes power levels on 160

Hello Pete, Exactly!!! On the higher bands, low power generally gets the job done. But digital folks on 160 need to rethink a few things. Ideally, we should ALL just bump our output up to 100 watts. But that's just not gonna happen. :-) I don't have the time right now to add more, but I hope

I have to disagree with some of what has been said about how much power to run using JT65. JT65 is a LOW SIGNAL mode, NOT a LOW POWER mode. We run 1500 watts into 20+ dB gain antennas on 2 meters for EME. Signals coming back from the moon vary between –10 and –29 dB Why limit yourself on

Re: Topband: JT65 on 160

"Overloading everyone's RX front end" is not correct. The problem is that these narrow digital modes are received using the full bandwith of the SSB filter. 73, Mike www.w0btu.com On Mar 17, 2017 1:19 PM, "Wes Stewart" wrote: Do you guys use lousy receivers for these

Do you guys use lousy receivers for these modes? Why would the mode affect the abilities of a receiver? Wes N7WS On 3/17/2017 11:06 AM, Jim Jim wrote: ...if you use high power you are going to start overloading everyone RX front end and you will be the only one able to use the band.

Jorge, I use only 35-50w on TB. A few years ago I worked VKs and Zls using only 35watts then went down the band a bit and worked one of the same stations on CW only moments later BUT it took over 900w to do it. That is just over 14db advantage over CW. Two other things to remember 1. JT65 is

While watching the waterfall for "spreading" on 160 and 80, Lee I've seen similar "results." My operating "mode"now is: 160: 25 to 30 watts set wid no ALC "ficker" 80: 30 to 50 watts set wid no 'flicker' Note: I run the 'mike input' control to a high enuff input I'll need to "back of"

JT-65 is a QRP mode, like WSPR where I use10W. High power can ruin it for everyone else. Read the documentation. On 3/17/2017 8:36 AM, Lennart m wrote: I do not agree with you Pedro. More is not always better. Use no more than you need. JT65 allows more noise than does CW, thus one doesn’t

I've used 100 watts on 160 - by accident, as I forgot to turn down the drive - I discovered that decoding can be a real problem at high power levels. I've seen signals from a station 30 miles (50 km) away that wouldn't decode because of spreading. I believe the main goal is to have little or

I do not agree with you Pedro. More is not always better. Use no more than you need. JT65 allows more noise than does CW, thus one doesn’t need as much power. 73 Len SM7BIC -Ursprungligt meddelande- Från: Topband [mailto:topband-boun...@contesting.com] För CT1EKD Skickat: den 17 mars

Hi Jorge Hi Jorge JT65 is no diferent from CW or SSB, more power is better...use no more than 50% of your amplifier power, if you have an extra fan use it on top of your amplifier.. Pedro - ct1ekd   Citando Jorge Diez - CX6VM : Hello so how much power to use in
