How to Calibrate frequency of the Tecsun PL-990x to have perfect SSB frequency readout

[@TheAx504]

Thanks for the correct instructions. Always useful to know. Cheers!

Thank you very much! Appreciate it a lot 👍 Greets from the Netherlands, T.

Just a shout out to you to say TY! Appreciate the info!🤓

Well ...in this case that you are discussing the S S B is used in a completely different way & the impression I'm getting is that fit perfectly alright because it gets you there in a very short time since simplifying the matter instead of using the old traditional method moving off a little bit at the time & playing around until find the zero spot I think is a simple & straight forward operation & that count when one have to manage a situation of piles of signals .

A mystery no more! Thank you!

Very interesting sr I like shortwawes radio for many years to captar lot world stationes

[@LovyDuga]

Thanks for the video. I wasted lots of time to unsuccessful calibration.

[@bubbaschwartz]

Thanks for your help, you really know a lot.

these days here we got overheat, outside 38C, at room did not switched on the air condition so 31C inside ... pl-990 was need to calibrate again by - 9Hz ... example was at 13, now is 4 ... or if was 0 it needs -9 ... when heat go away will need again calibration

[@stephank.8453]

In my case, the deviation is more than 1khz and the described method does not work. Any idea ? Thank you.

[@OfficialSWLchannel]

make sure you did not get a early test model from China rather than the latest firmware, this works with all 990 and 990X

[@kenmcfarlane226]

Great video.Thanks.Do you need to re calibrate when radio is switched off or does calibration hold?

[@babisglykiotis2723]

calibration hold even if turned off

[@christophersteer505]

You begin by saying " once you've tuned" well, how do you tune, we are novices that's why we're watching you and like videos,please from the beginning., thankyou , all the best Rs London boy

[@wu2u]

An easier way is to tune into an SSB amateur station and adjust the fine tuning until the signal is perfect, then calibrate. 99% of all transceivers on the air today are spot on and are usually tuned to a 1mHz increment. After this process you can test it out on a few other SSB signals and with the majority being tuned in correctly tuned in will confirm accurate calibration.

Does this radio have air band?

[@OfficialSWLchannel]

no

[@CanadianPrairiesShortwave]

great info

[@malmonmalmon1794]

Is it the same procedure for PL-990?

[@OfficialSWLchannel]

yes

[@hanny-c6m]

How to uncalibrate in case you mess up?

[@OfficialSWLchannel]

you just re calibrate

[@hanny-c6m]

@@OfficialSWLchannel Can't go back to factory reset before calibration by pressing the reset button on the bottom of PL-990X?

[@scottbelcher9026]

Thank you! I at least understand more what synchronizing is now!!!

[@babisglykiotis2723]

Hi, Thanks for info, just got my 990x ... here my case, ssb was by 13,14 hz off ... reset the radio (underneath) just for testing was spot to 0 ... video with 13 hz off at channel, will upload with reset & there after, sometime later, 73 ... EDIT anybody know how to calibrate the actual frequency at LW? it seems by 1 khz off, example medi radio 171, seems getting better at 170 (no video yet)

[@OfficialSWLchannel]

you simply tune to make zero beat and hold the LSB or USB button until the display flashes

[@babisglykiotis2723]

@@OfficialSWLchannel many thanks for fast reply to help, i done it, is easy indeed, but this seems does not help the freqs at MW & LW in normal operation (no synch, no ssb in use) which may be off by about 1 khz ... will try again

[@salimchiadf4ifb60]

Hi thanks for this video, Can you tell me if a same procedure for the xhdata d808 is existing please? Best regard Salim F4IFB

Good aural training 😁
