Tiny for HF radio alignment
Hello,
?Although I have not still got a TinySA device yet I would like to get one in order to align some radios that are waiting, but before doing nothing I would like to know your advices since I have some doubts. Thanks in advance. I have some HF receivers that nedds some IF alignment and since the Tiny can be used as a signal generator I would like to know if this device is reliable in this aspect. Right now I would like to do a full alignment to a Panasonic RF2200 receiver, as described in the service manual I would have to do the indicated procedure? in pages 10 11 and 12: Could be used the Tiny?? Another question, I have a pair of Drake HF receivers but according to the manual nedds a 50 Khz-30 Mhz signal generator and the Tiny starts from 100 Khz, Any trick in order to down to 50 Khz. And last question, any reliable seller on aliexpress or amazon? Thanks again for your valuable help. Any thoughs and advice are greatly welcomed ! ? |

Thanks again for your valuable help. Any thoughs and advice are greatly welcomed !If you are interested in radio, construction and antennas, then a VNA may be of more use than a Spectrum Analyser. Ideally you could own both, but I think for your purposes something like a cheap NanoVNA may be worth considering. There are plenty of on-line tutorials and other overviews, that can maybe help you decide. Regards, Martin |
Hi there, Enrique & Martin. I strongly suggest the possession of both, Nano-VNA & TinnySa, recommending the Ultra one. Have a good midsummer all of you, provided you are located on the northern hemisphere!

They are instruments or tools, designed for different purposes, but there is some overlap between their individual functionalities, and they tend to complement each other quite nicely. Regards, Martin |
Martin yup! As VNA is a vector network analyzer and TinySA is a spectrum analyzer with signal generator function as a bonus. 73's de OH7TI ti 18. kes?k. 2024 klo 15.20 Martin via <martin_ehrenfried=[email protected]> kirjoitti: On Tue, Jun 18, 2024 at 12:02 PM, Ilkka Sysila wrote: |
Although I have yet to use the Tiny SA to align receivers, it should be an acceptable tool for that purpose.
I have the Tiny sa APP installed on my PC that has a great remote GUI for the Tiny, I recommend that also. It will generate CW signals by setting the span to zero Hz. As far as below 100 KHz, that I don't know. There are a great many youtubes showing all of the functions, operation, limitations and many applications for the Tiny. I keep a list of those for reference. As mentioned, another tool is the Nano VNA and an ideal complement for the Tiny. Do your research so as to avoid bad clones, buy from approved sellers. My devices are the Nano VNA H4 and the Tiny SA ultra. Not perfect but for the price, the closest thing to my bench full of HP/Agilent. And here on groups io if you have questions. 73s |

It is a very useful device but not for this application. I read the alignment pages in the manual that you posted.? It is a very involved calibration procedure.? The tinySA Ultra will do the job for you when in signal generator mode.? I checked mine this morning and it will generate the 455 kHz. with 40% mod at 400 Hz.? It will easily generate the HF carrier frequencies specified in the procedure.? And as Erik (the product developer) stated it will output 50 kHz. for you? (I checked this on mine). So just buy from an approved vendor.? Do not be tempted to buy elsewhere unless you want a counterfeit clone with poor performance and no support in this group. Roger |
Hello Roger,
?Thanks a lot for your useful advice, in my country there is an approved vendor, I will buy the small tinySA Basic and an analog multimeter, a Sanwa EM7000.? You say with the Ultra version, cannot be made with the Basic one? The only difference I notice is the frequency coverage. This canadian guy has made an alignment with the Tiny: I do not know if I will able to align the Drake R4B tube? receiver is more complicated or send it to be serviced: (pages 31 to 43) ? ? And a Drake SPR-4 transistorized but the alignment seems a bit complicated too, (page 22): ?https://www.wb4hfn.com/DRAKE/DrakeManuals/PDFDOCS/SPR-4_Manual.pdf Kind Regards. |
The basic NanoVNA is probably sufficient to your needs. My NanoVNA H4 goes to 1500 MHz. I also have a TinySA Ultra. It goes past 10 GHz. I do need that since I am a microwaver, but I doubt you need that frequency coverage, Zack W9SZ On Wed, Jun 19, 2024 at 9:10?AM enriqueeeeee2001 via <enriqueeeeee2001=[email protected]> wrote: Then, I would get the Ultra or with the Basic should be more than enough for my purposes? |
You can use a simple flip/flop to divide? by two. Dave - W?LEV On Mon, Jun 17, 2024 at 11:15?PM enriqueeeeee2001 via <enriqueeeeee2001=[email protected]> wrote: Hello, -- Dave - W?LEV |
enrique,
? I just received my new TinySA Ultra today and have already done a full alignment on a 1960's vintage Japanese 6 Band radio.? Easiest alignment I've ever done.? The radio sounds so much better now. ? If you haven't already received your TinySA I am sure that you will be pleased with it when you do. Terry |
¿ªÔÆÌåÓýWould appreciate some details of exactly how you went about that, Terry.Did you use a wideband noise generator? Mike - M0MLM From:

Hello,
Just to say that I have ordered a TinySA Ultra, some bnc/SMA adapters a DC blocker and a Sanwa em7000 multimeter. I bit late I have realized that I had a HP 400EL AC multimeter that also read dB's, I have already got a swith step attenuator. I hope that with all these instruments I will be able to make the alignments, I do not understand some alignment stpes? in the Drake's. First of all I am seeing videos and reading about electronics, decibels, attenuation..sRF IF's in order to understand what I am doing.,and of course knowing how a signal generator works. Regards. |
enrique
? Good luck with the alignment.? As others have noted, the Drake alignment is rather involved.? Another good place for questions regarding the Drake would be the Drake Radio group.? There maybe somebody there that has the expertise to answer your questions. Terry |
¿ªÔÆÌåÓýAh, OK.? I was thinking you were looking at the IF response on the SA.Mike - M0MLM From:
