Re: [Flexradio] [SPAM] Parallel port cards?

Any parallel port interface card will work. The critical requirement is to make sure it is putting out the max voltage as specified by IEEE 1284, which is 5.5 volts because the parallel interface bit bangs the SDR-1K and uses no other of the printer based protocols. I have used one from Lava

Re: [Flexradio] FlexRadio Digest, Vol 45, Issue 4

Pete, I use a USB port for the SDR1000 USB/Parallel cable and another one (on a separate USB 2.0 Card) to run the HPSDR with two separate instances of PowerSDR running. So you may not need the parallel port. I have a parallel port on my old Dell but I only use it to connect a JTAG programmer up

Re: [Flexradio] Parallel port cards?

Thanks for the various recomendations. I'll give the dual USB port option as suggested by Bill a try first. Time to get the Delta44 out of the old pc, get Mercury configured in the HPSDR setup - so much to do, and the holidays are almost over and it's back to work tomorrow! Pete, N3EVL

[Flexradio] Parallel port cards?

Does anyone have any recomendations for parallel port cards (PCI) since my new pc did not come with one as standard. I was previously using the USB port for my SDR-1000 via the usb - parallel cable then switched to using HPSDR Ozy directly via USB but now I want to use the USB for HPSDR with

Re: [Flexradio] Parallel port cards?

Yes I bought a SIIG single LPT card via eBay. I use it with DDUt to control my Quadra Amp. I found that SIIG com port and lpt boards work well and drivers are easily obtainable. But generally add-on cards do NOT have the stock parameters that moboard Lpt ports used to have so you may have to

Re: [Flexradio] separate VAC's

At 01:49 1/4/2009, you wrote: It is not now possible. This and many other things of similar ilk are going to be much easier in the new code. OK, I know I cannot have two pairs VAC channels. I still have a way around this. I am using the actual speaker output jack on my SDR-5000, choosing

Re: [Flexradio] carrier on ssb

It is not actually a carrier but LO leakage from the commutator ic FST3253 and there is no adjustment you can make to null it on this implementation. I use sdr1k with the 100w PA and I have measured this leakage to be -20dbm @ 160m (70db below 100w)and 0dbm @ 10 m (50 db below 100w but only 30

[Flexradio] vac glitches?

I am running the vac at MME 512 buffer and 8000 Hz sample rate on PowerSDR (several versions including the latest) and an sdr1000. I am receiving the output in a spectrum analyser from virtual cable 1 running at 8000 Hz sample rate and doing 4096 point ffts. ABout every five seconds I get a

Re: [Flexradio] vac glitches?

What sound card are you using for the SDR-1000 and what is the audio sampling rate and buffer size you are using? What version of VAC are you using too? As per the VAC configuration article in the Knowledge Center, you should set the VAC sampling rate to 48 KHz rather than the 8 KHz you have

[Flexradio] Using the 100watt amp

I have a spare SDR100 with a 100watt amplifier, I would like to try that with my HPSDR setup, can someone please give me some info as to how to set up the 100watt amplifier to act as a stand alone 100watt brick. I assume that there are some pins on the RFE connection that need sorting out.
