Feature Request: Add option for Disable PA on each Xvtr Band
|
I connect my HL2 to and HF antenna with PA enabled on the ANT jack and VHF transverter(s) using split IF at 28Mhz at about 0dBm using the new IOBoard Aux Rx and RF1 for the output. The PA needs to be disabled to make it work right on VHF.? The IO board with my customized firmware is handling the J9/J10 switch and band decoder output OK.??
I can disable it (and have Disable T/R in low power = true) in the Config menu but it would nice if it was automatically configured on Xvtr band change for seamless operation.? ?An example of this is the Thetis XVTR setup.? ?Not all transverters use low power IF drive so controlling it per band is most effective.? ?Along with that , per band, is option to set drive level as each can be different. Regards, - Mike K7MDL |

Hello Mike,
I can program this feature, but I think is is not optimal. The correct approach with Quisk is to create two radios, one for HF and one for transverters. Then select the correct radio when Quisk starts. The HF radio shows only HF bands and the power amp is enabled. The transverter radio shows only VHF and UHF bands, and the power amp is off. If you have transverters that need the power amp, there is a third radio. One problem with controlling the power amp from the band screen is that you probably need to control the RF input on the IO board too. This clutters up the band screen. Is there something wrong with using separate radios? Jim N2ADR |
¿ªÔÆÌåÓýThat is a reasonable no coding solution.? The main limitation is a program like WSJT-X cannot change bands from, say, HF to 6M or other VHF bands without first stopping the radio and WSJT-X, and restarting each.? I know you have a settings to start WSJT-X on RX0, have not tried it as I often run multiple instances for multiple radios.? ? I am used to my K3 with the 6M and HF antennas and the xvtr interface for the VHF Xvtrs, I just hit the band button or memory and instant change for all bands 160M through 1296.? ?Running a program like WSJT-X can jump between any band like 6M, HF and VHF seamlessly.? In the case of the 5-band Xvtr it switches bands fast and silently with no relays for when I manually scan for contacts during VHF contests. ? The HL2+IOBoard is capable of the same seamless coverage with the RF1 and Aux RF connected to the Xvtr(s) and HF on the ANT jack.? I have the DB9 wired so that I can just swing the Xvtr control cable and the IF coax lines between the K3 and HL2s, one can replace the other now. ? I am a complicated user scenario ?. ?
