Re: LimeSDR

Deff not complaining about black box op's at all. Hence my comment in between the quotation marks. 

Indeed one of my favourite tests is a Chuck test named after a very good friend who is 100% black box. How would this work and perform if I gave it to Chuck and said set this up. That means more to me than all the Lab Rat tests as it is a real world test.


I got an early 1.4 and all I did was break the inductors off with a pair of tweezers.  

The word "choke" "inductor" and "filter" seem to be getting transposed. 


All I did was remove the inductors. 

Remember Lime did not say how good it is on 100kHz to 3.8GHz just that is covers those frequencies.


My TS2K comments were based on comparing what I saw on beacons with my TS2k/Funcube Pro+ (my benchmark) and ANAN 10e and prob my 2m Kuhne but I do not recall.  The FCD+ far beats the TS2k on weak signal RX on VHF. But I saw little difference between the Lime and the TS2k on the VHF beacons or on MS.  I prob checked it on 222 too but do not remember. On all bands, including my quick HF test, I added band pass filters which obviously you need to do with the lime as it is a wide band TX/RX. No way I would want or expect Lime to design filters into the lime as they do not know what I want to do with the lime. 


Hopefully that makes my comments a little clearer.

Re: LimeSDR

Rob Ram
 

Thank you Allan for your reply. I have not modified my LimeSDR. It is in original condition. It seems fairly obvious, that some form of modification is necessary to get it to work for ham radio use.

My engineering experience tells me to modify only when you have proven, analytically, that the modification will work. This is especially true with tiny iti biti SMD� PCB parts. The Linear LTSpice is a very helpful SPICE simulator; its easy to use and provides a wealth of insightful simulation results and is free from http://www.linear.com/designtools/software/. The alternative is to use the SWAG method ;-)

As I mentioned before I hope that I can get the LimeSDR to really work. I am most interested in using the LimeDSR as a VNA; but first the RF stages must be modified. Just need to modify one TX and one RX path. Wide band is the goal. There are methods of using simple resistors for the sampling bridge; no need for directional couplers.

Any one have data useful to create a SPICE model(s) for the RF transformers?

I decided on tuning 50 to 80MHz because that band is relatively free from signals here and the Lime minus its tiny shunt coil receives that band really well.

I�m using a low pass filter with a sharp cut off about 31MHz and a band pass filter 50-80MHz and with these the local FM broadcast stations are almost eliminated from the converter output if I tune it to say 88.5MHz I see only -102dBm.

Around here 125MHz to 155MHz has lots of very strong aircraft signals so any converters using that band would need a decent filter.

�

Is your Lime RX-L input still fitted with coil MN34, 8.2nH. The Lime site has details for removing it. If it�s still in place you�ll get poor results because it represents a shunt of around 1.5 ohms at 30MHz. The two filter capacitors are 510pF so at 7MHz are about 90 ohms. The input has a 470pF in series with the connector and at 7MHz, 50 ohms this will halve the signal. Adding 100nF chips across these will help but I haven�t done this yet.

Hi Allan,

What is your up-conversion frequency? I have used the Noolelec up-convertor which shifts the HF spectrum up to 125 Mhz. However; according to the LimeSDR input ranges, the starting range is 700 MHz. While the up-convertor does work, its not really up to the performance of a high performance HF receiver. Not only receive, but transmit is also a workaround problem for HF.

I think the best solution is to design the input and out put filters for HF and VHF use, regardless if direct or transvertor use. Need SPICE models primarily for the transformers, to design the i/o filters. While direct connection may work, a transvertor scheme may work better. The blip in the middle is eliminated. The spectrum is shifted to avoid the zero image of a direct conversion scheme. The LimeSDR phase correction does not really work well, especially for weak signal communication. On VHF I see the blip in the middle which is indicative of IQ phase and amplitude anomalies.

Hi Numeric

There�s lots of information and grumbles from buyers re the Lime SDR on the Net and I�ve added a discourse to my website.

It seems the designers and advertisers mustn�t have been in sync during the period from inception to manufacture.

I assume it�s that, otherwise it would seem to be a confidence trick to release a piece of HF kit that is 80dB down on expected performance.

After its release the Lime people suggested some modifications and indeed carried these out before supplying later examples.

Performance at HF is way down on what is generally acceptable but the thing is certainly tunable from below 100KHz.

I�ve been testing the thing and I�ve decided that the obvious way forward, other than selling it, is to add an upconverter.

My idea was to make such a device which could be easily reproduced by anyone armed with a soldering iron and a few pounds (or dollars etc). Yesterday I finished the construction of a simple prototype which allows one to hear signals down to a microvolt or two from a few KHz to 30MHz.

There are advantages of using the Lime, or any other SDR, this way because spurious responses can be minimised.

I haven�t tried it on transmit, but again a converter may be the best solution for users in the HF bands.

Essentially the Lime is OK if you�re a radio ham and prepared to experiment, but not if you�re a black box user.

Barry,

Thanks. I read that too. I do have the original fuse. I looked at digikey and found a replacement that is 2amp hold and 3.5amp trip instead of 4 amp trip. For now I will jump it out. I may leave it jumped out and add an ordinary fuse on the output of the 5v supply board. The hermes board itself has a dedicated fan going in (the case is still a work in progress). I never thought to heat sink the other on board regulators. I will likely do that. I will be on the sdr computer hopefully in the next hour. I will post my log.

Re: LimeSDR

paul newcombe <G6YZC@...>
 

I am with Mike on this one. My Lime does exactly what Lime said it would do TX and RX from 100kHz to 3.8GHz, or at least to the best of my knowledge as I have not tried it all the way up to 3.8GHz.


It is by far the best 100kHz to 3.8GHz tx rx SDR on the market especially for the price.


Once SDR Console has TX support for the Lime it will make a very nice 2m weak signal EME SDR rig. Again the best out there at the moment I would say. I certainly am looking forward to using it on the uW bands. 


I therefore do not see what the problem is? What band pass filters are you putting in front of it on HF? Although I have no interest in HF myself I did try it on HF RX once I did the simple mod and even using some very wide band filters I was more than happy with what I saw. Obviously if I were a 20m contest guy then I would use better filters than I grabbed for the test. On 6m and 2m it seemed to be as good as a TS2k on RX by eye. Supporting pics are posted on the lime support web pages. 


The main complaint that I am reading is not about the lime but about the buyers about themselves. Most seem to be saying "I am a black box operator" (which is great) "and the lime is not a black box therefore the lime is at fault so fix it!"   The lime is what it said it would be.

I've been thinking of getting a LimeSDR, and this thread has made me think maybe not. Your screenshot shows an impressive bandscan, with a large 2MHz wide chunk that seems to be a lot quieter than the rest of the signals starting about 1.8MHz and 2.8MHz. Is this a performance issue? or do you have a filter for that part of the band inline or is the band just quieter for you at that point in time?

Hello,

I started playing around with the LimeSDR. So, far not really
impressive. I Tried using the Noolelec up convertor but has poor
performance compared with the QSR1 16 bit A/D direct sampling SDR
receiver. The specifications state a frequency range of 100 kHz – 3.8
GHz for the LimeSDR with an application for ham radio use. However; the
RF input range is broken into three bands:

1. Low 700 MHz - 900 MHz. That is 700 MHz not 70MHz!!!

2. Wide: 700 MHz - 2.6 GHz

3. High: 2 GHz - 2.6 GHz

What the hell happened to 100KHz to 700 MHZ?

The transmit mode does not even match the receive bands.

Transmit provides two bands:

1. 30 MHz - 1.9 GHz

2. 2 GHz - 2.6 GHz

Obviously the LimeSDR does not serve the HF and the VHF ham bands. OK
for the 900 MHz ham and micro wave ham bands. I was hoping to use the
LimeSDR as a wide band VNA (Vector Network Analyzer); but the filters
screw up my plans.

At least the LimeSDR builders could provide SPICE models for the
transformers and the LMS7002M RF input and output ports. I suspect that
the LimeSDR could easily provide broadband continuous coverage if the
current RF stage were replaced. Hoping for a positive outcome, but at
currently the LimeSDR is a POS!

Also, the LimeSDR gets HOT!! May be about 110 degrees F.

Rant:

Why the 700 MHZ coverage, unless the evil telcos out there want to steel
the 700 TV broadcast band for their own profit. Best part of steeling
public spectrum is that you can get cell phone users to pay to access
their own spectrum. I know about the FCC auctions; should have been
halted from the very start. Recently many TV broadcasters have elected
to give up their spectrum, they are going off air. The FCC fcc.gov has
identified the broadcasters going off-air.
