SDR 1000 issue

KF5FWU — Sun, 04 Dec 2011 10:49:56 GMT

I've been useing the sdr 1000 for a little over a year now and I LOVE IT. I have recieved 2 reports from the same guy that i am transmitting on 2 frequency. For example i was transmitting on 29.050 and he said i was also transmitting on 29.028. So i tuned in with another reciever and i cant find where its xmitting on another frequency.

I've been really paying attention today and i do recieve on 2 frequencys. For example ,, im listenin to a couple guys on 29.030 with a signal of -77.0 dbm. I also see the same signal on 29.058 with a signal of -125.0 dbm,, so the signal is much lower than the transmitted frequency but it does show up.

My qeustion is,, does anyone have any idea what might be goin on and what i can do to fix it.

Thanks , Billy.

Flex Radio demo and W7 64 bit

vk5cp — Sun, 13 Dec 2009 08:09:49 GMT

What's my chances of getting the demo software to run under w7-64. It wants to install .net (which won't run under W7).

Invalid Sampe Rate

jlsxe — Sun, 25 Jan 2009 19:19:14 GMT

I just got a Flex 1000. As soon as I click on the "Start" I get PORT AUDIO ERROR "Invalid Sample Rate"

Could anyone tell me what I need to do to fix this error?

Is anyone successfully running on a 64 bit system. All looks ready to go (using fa-66) but I can't get the radio to turn on. I have tried two PCI express parallel adapter ports in new Gateway SX-2800 but I cannot bring the Flex to life. It worked fine in an older Dell with a regular PCI/parallel card from SIIG. Wonder if problem is PCI express? So I'm not sure it's the card or the 64 bit vs 32 bit system.

SDR-1000 Transmit Frequency Limitations

G4HUP — Mon, 16 Mar 2009 11:03:12 GMT

Having just acquired my SDR-1000 I want to modify the allowable transmit frequencies to align with my microwave transverters - but I can't find any information on where this is set. Looked through the handbook/userguides, and I may be missing something somewhere, but any help would be appreciated!

Thanks for any help!

Deaf SDR-1000

VE1DAS — Sun, 15 Feb 2009 09:34:58 GMT

I bought a used SDR-1000 (basic QRP with no ATU) and it worked great for a few days. It had all the updates including better preamp on the RFE and overload protection diodes installed at the factory. After a day or two of fun, I tuned to the Broadcast Band and was listening to a local AM station. After listening for a half hour or so I heard a sort of "hiss" in the audio that lasted a second or two. The audio dropped out and came back on. I thought the station had gone off the air temporarily and paid little attention to it. When I came back to the screen later, I noticed the signal was S-9 instead of the 40 over that it was before. BTW, I had the preamp set to low because the signal was very strong even though the station is 10mi away. When I switched back to the Ham Bands or any HF frequency, there were no signals. I can still hear strong Broadcast stations on the AM band though. Otherwise, there's lots of "noise" in the Panadapter but no signals. I have tried another Delta 44 card and no change. With my old tranceiver on dummy load, I can transmit and hear the signal on the Flex. Changing the preamp settings on the Flex does seem to affect the level of the weak received signal from my other rig, so I'm thinking it may not be the preamp. Also, when I connect and disconnect the antenna from the Flex, there is no noticable difference in noise. I have even tried using a signal generator to inject a weak signal after the bandpass board and the receiver is still almost deaf.

Help anyone?

15 meter High SWR faults .. fixed

K0VM — Sat, 19 Apr 2008 18:03:07 GMT

For some time PSDR has been giving indications of HIGH SWR on 15 meter band even though external indications were < 1.5: 1. These occurred on voice peaks, or High output CW (tune) > 80 watts. Readings were normal a low power and then suddenly indications of High SWR and several hundred watts output on PSDR with normal readings on external meter.
After some debugging I discovered the that the readings were caused by RF pickup on the digital line running between the PA and the TRX board. This signal is routed in a multiconductor shielded cable between the PA and the RFE board and then a single unshielded wire from the RFE board (J3) to the TRX board. Replacing the unshielded wire with a shielded wire grounded at the RFE J3 connector solved my problem.

SDR-1000 No TR transition on RFE J2

n2rd — Fri, 29 Feb 2008 20:06:24 GMT

I have a weird problem with either my RFE board or software setup.

As you know, the J2 connector on the RFE board is used for the internal or the external transverter.

RF wise, the port is working. I fed in a signal from a generator to this port and it receives well. Measured the output during transmit and got 0.8dBm on this port. All within spec.

The problem is with the TTL TR signal that is supposed to be with the RF on this connector. If I set it up with Positive TR Logic, then the DC voltage on this connector stays at 0v whether I am transmitting or not. If I set it up with Negative TR Logic, then the voltage stays at 5V whether I am transmitting or not. The problem is that it is not making a transition from 0 to 5V or vice-versa.

This has me baffled.

Any help appreciated.

Thanks,

Noise generated from Parallel Port

wa3gfz — Sun, 06 Jan 2008 12:24:58 GMT

The problem is most prevalent on 28 Mhz (also downconverted
144 Mhz). When I drag the tuning, the parallel input port on the radio
causes noise in the audio and spectrum. It does this even when the radio is
off. Everything is grounded well and I tried an entirely different
computer and parallel cable. I tried grounding different points with the radio off. I found that grounding the 5volt line near the connector helped some. I bypassed the 5 volt line at that point, but that did not cure the problem. This noise also causes the XVTR Tx relay to clatter when that option is checked on the XVTR screen. HELP! Paul WA3GFZ

Clicking relay during tuning in transverter mode

wa3gfz — Wed, 02 Jan 2008 00:30:54 GMT

Hello all, Just got the 2 meter unit hooked up. This is a factory built unit. The keying polarity is opposite of what it says it should be. When I tune using the mouse wheel, a relay clicks proportional to the mouse wheel's motion. I tried changing the polarity as well as TX enable in the transverter screen, but nothing cured it. Thanks for any help. Paul WA3GFZ

I subsequently found that the TX RX B+ lines were wired backwards at the DEMI factory. So much for testing before shipping. But the relay is still clicking due to noise induced by the parallel port.

sdr pc board

just came across the ac5og's excellent articles about SDR on 2002 QEX,
relating to pc board(s), so here to ask where are available.
Spotted the Linux gnu software and planning to give it a try .

Fan Noise

Has anyone disabled the fan or otherwise limited the noise via a resistor, rheostat or some sort of thermistor?

Frequency problem with my new bought SDR-1000

OE8CCQ — Sat, 23 Jun 2007 17:26:46 GMT

Hello to all.

I'm new with the SDR and a think there is a problem.

Equipment: SDR-100 + ATU + 100W PA + 2m XVTR

When i check the receive frequency it changes from time to time. The difference to a reference transceiver is up to -120kHz and it's not possible to calibrate over this wide range.

Please have anyone an idea what's going wrong????

HI ALL

I AM NEW TO SDR

SO I AM THINKING OF GETING THE SDR 100 TO START WITH

CAN ANY ONE TELL ME WHY EVEN WITH THE 100W VERSION THE OUTPUT ON THE 6M BAND IS IS ONLY 500MW

IS THERE ANY WAY TO BOOST IT ON 6M TO GET 100W

SDR-1000 RFE board schematics

dk9nw — Mon, 09 Apr 2007 07:50:01 GMT

Hi,

Just bought a SDR-1000.
Now try to find out how all schematics fit together.

I found all that and downloaded it:
SDR-1000_schematics.pdf containing PIO,TRX and BPF
100WPA_v1.3B_Schematics.pdf containing PA
RFE_v1.4a_Schematics.pdf containing RFE

but that RFE laylout is not up to date. It contains the SGA-4586
This schould be the SGA-8286 and the resistor R2 should be different.
(see ECO025-RFE_Preamplifier_Upgrade.pdf)

Where can I find the scematic of the RFE board, that I have bought ?

I am new to all this SDR but it seems to me that the solution to the problem of how much energy is being wasted lays with the owner who could switch it off if he thinks he can not afford a few pence on the electricity bill. I am sure Flex-radio are aware of this issue and feel that it is something that does not need addressing.

There are only two alternatives to this problem. Either stick with it or go back to the whistles and bells and the multitude of never used usless buttons on a conventional rig.

SDR-1000 for sale

Paul Ermisch — Fri, 08 Dec 2006 23:08:35 GMT

Basic 1W system with RFE board. NO CASE, NO CABLES, NO PS. $450 PayPal or MO only.

I picked this up from a previous owner who (I believe) purchased it new in 2004. No mods that I can see although it does appear to have a factory-installed daughterboard installed. I seem to remember something about an upgraded oscillator/clock - anyway, it has that as well. I played with it for awhile but never used it for transmit.

ATU overpriced!

sm0jzt — Sun, 29 Oct 2006 12:08:39 GMT

The LDG Z100 has a suggested price from LDG of USD149.... Looking at the Flex-Radio pricinginfo
I fint that this option comes for USD235 from Flex-Radio.

That is quite some difference for the same unit. Iám not impressed and awaiting
a good reason for the pricedifference.

Until then I feel that Flex-Radio are selling a fairly overpriced unit with teh SDR1000.

High stand by current - A fault?

sm0jzt — Sun, 29 Oct 2006 11:33:27 GMT

Hi there
I have a brand new SDR-1000 her at home for evaluation.

I have found that the unit pulls 840mA from the 13.8 supply during stand by (big switch off).
When Switch on the unit pulls 930mA.

I´m sure there must be something wrong with the unit. This as I can not get any power out
of the 100W PA. I have not yet tried the exiter-part to veryfy if there something wrong
with this to start with.

Anyway. Any other of you having the experience of a very high current drawn in standby ?

(the PA heatsink gets warm during stand by of course )
