I hope that it is possible, an that the frequency counts the right direction, not the other way, reason is then the oscillator frequency of the transverter(s) Sorry that I can not help you right away, Someone else on the list? happy experimenting 73 peter pa0pvn groeten Peter petervn(a)hetnet.nl <mailto:[EMAIL PROTECTED]> ; pa0pvn(a)hetnet.nl <mailto:[EMAIL PROTECTED]> ; pa0pvn(a)gmail.com ; pa0pvn(a)amsat.org . ________________________________ Van: [EMAIL PROTECTED] namens David Hilton-Jones Verzonden: zo 1-4-2007 14:11 Aan: flexradio Onderwerp: [Flexradio] Transverters I have been used to getting a reply to my queries within seconds from the ever-helpful Flexers. The fact I haven't had a reply to my last query makes me fear I've asked a very stupid question! I'd appreciate a comment in response to the following: Having had fun playing with my SDR-1000 with 1 watt on HF, it's now time to get it tamed for VHF work, which was the object of my purchase. I have the 144MHz DEM transverter installed. I will be using that to drive transverters for other VHF/UHF bands. If, for example, I am using a 144-1296 transverter, I presume I have to click on the 2 metre button and with the 144-1296 transverter connected to the 144 connections will be QRV on 1296. is it possible to get the display to show 1296 rather than 144? As far as I can tell, the XVTR Setup only works when using an HF signal to drive the transverter from the HF output of the SDR, or am I missing something? 73 David, G4YTL David your thinking is correct regarding transverters to cover other bands beyond 2 meters. The HF block is used as the IF so we only require the card for the band of our choice. With the basic SDR 1000 trx hardware which I think it's a basic 160 to 10 meter standard for amateur use. >From 2 m and up we just add another converter card to suit the band of our choice. For transmitting on vhf to uhf it gets a little complicated. The design of the transverter card caters for the transmitter and the receiver. The hardware switching and the software upgrade is the challenge. It's normal that the frequency readout will read the IF frequency which in most cases the 10 meter band say 28 to 30 mhz. cheers, Aisea, 3D2AA -- No virus found in this outgoing message.
