Frame and Start


"Don"
 

I'm a newbie on WSPR. What is the most common number for Frame and Start? I just completed the Ultimate2 QRSS kit. I plan to beacon on 30 meters. Thanks.

I run mine on START =0 FRAME =4

This means the kit is transmitting for 50% of the time it is on.

People using using standard PC TCEIVER setups, often have much larger frame values which produce a transmission for ten percent of the time while receiving spots for ninety percent of the time.

I am actually waiting for the general WSPR users to question the use of TX only beacons where users don't reciprocate by setting up a receiver to return the favour of being spotted by people who make the whole WSPR system work - the people who run receivers. A kit like the UQ2 doesn't actually make it that easy to run a receiver since the timing of TX and RX would be done by independent devices, unlike the situation where an operator uses a PC and the WSPR program which coordinates everything.?

I have been experimenting with running a UQ2 kit on say 20 meters and an RX on say 15 meters or maybe 40. That way I could repay the favour of being spotted. There is some receiver desensing on 15 meters when my UQ2 is transmitting on 20. I could run a receiver with an active antenna or a non optimal long wire, at a different location - a relative's house. That way, I could operate both setups on one band if desired.

73s?

I just looked at the charts and they are in the Photos section (since they are graphic files... and they display better there than in the Files area...) under "WSPR TX Times".

On 30 meters, the recommendation is 20% or less transmitting time according to Joe Taylor, the guy that invented WSPR.
