You seem to have calibrated everything except the FX773 ! There is a calibration menu to fine tune the FX773. It would then mirror the output from your fine-tuned test equipment
Have you ever worked on an FT-100D. I have looked at some modifications but haven't touched it in fear of letting out the magic smoke. 73 Thanks for the videos, they are very well made and informative. I worked for a German company in the US and your accent brings back memories of former colleagues.
Like we say here in Portugal “too much straw”. Meaning that the unit has too many information and bad accuracy. Too much toy for my taste. Thank you Peter for the nice video. 73 Victor
This definitely is a sharp looking piece of equipment, but I wonder if the FX773 was designed to be a calibrated piece of test equipment or just a high-end relative watt and SWR meter. Nice job in pointing everything out.
In my comparison test I didn’t recalibrated the fx773 unit, it’s so as arrived from MetroPWR, if u want i can send the link of the comparison video from FX773 vs R&S NRVS URY-Z4
IMHO the FX773 screens are far too cluttered with rarely needed infos. Bigger fonts are certainly needed - even if some information must be omitted. The only other option would be to output the screen information to a big computer monitor. However, even if the readability is fixed, unstable and incorrect readings do NOT inspire any confidence in the meter's accuracy.
Really a nice looking meter, however looks do not solve the internal issues. Shame that the quality is not as good as the looks. Why they put such small font's is crazy. Thanks for sharing Peter.
I wrote to the owner of MetroPwr but he reacts little bit angry about my question. The manual is also incomplete and some indicators are not really discribed. I think it will be more a "Schätzeisen" But thank you for your great videos and this review.
@@ronnymang2360 Ich denke auch, dass es nur schön ausschaut, aber eben nicht zuverlässig misst. Leider ist mit einem geschicktem Layout, Farbwahl und der Tatsache, dass es digital gebaut ist, of ausreichend bei Kunden , sich sowas anzuschauen und zu kaufen. Das LP500 war wohl eines der ersten Geräte die sich Monitor nannten und andere machen es nach. Digital bedeutetet eben nicht immer auch gleich akkurat.
@@DD4DA Da hast du recht. Metropwr stellt ja auch VNA's her und ich ging davon aus dass es auch vernünftig misst. Aber nachdem ich mal einen Bird-Leistungsmesser angeschlossen habe konnte ich beträchtliche Abweichungen feststellen. Die Bedienung ist auch nicht wirklich intuitiv und man benötigt gute Augen. Werde mich nun doch für das LPA-500 oder Microham SMORF entscheiden. Aber das SMORF kostet natürlich einiges mit den Richtkopplern. Aber mir ist die Anzeige von Impedanz und auch Blindwiderstand usw. wichtig. Das macht das Metropwr FX-77# auch, doch wie genau ist das Ganze!? Beim LPA-500 konnte ich dieses leider nicht finden, sonst hätte ich es längst bestellt. Da ich einige Microham Geräte nutze ist das SMORF sicher eine gute Ergänzung. Mal schauen was der Weihnachtsmann so bringt 😄 ((73))
While I understand the genuine negative feedback, this should go to the vendor. Give them an opportunity to correct. If they don't show interest in correcting then sure, give them a public wrap. This looks like a very featured unit with great ideas. Just needs to get the accuracy right. Once they do this will be a far better meter than most.
Looks very nice, but I do like my NISSI DG-503. Maybe you can give your thoughts on this unit. I have 2 units and they both read the same. I don't know about calibrating this unit.
Seems to me the unit spends more time reading the temperature and humidity than it does reading RF power. After that showing of not being accurate and it also drifts, I would not trust the time, temperature or humidity ether.
Hi Peter, I told a lot of time to Antonio that some fonts are too little for this nice big display… at the beginning they were smaller than latest firmware, the units i sold to my customers worked well, they are stable in reading swr and watt, the factory tuning is not the best but it’s very simple to adjust yourself and compare to your r&s, my advice is to contact Antonio about the issues you found, he will send the new one i think it’s defective, last period for Antonio was bad, he stayed in hospital. However the comparison with LP-500 it’s not honest because it cost more than double here in Europe, (the FX773 price with 3kw coupler and italian vat included is about 430€) so the comparison with laboratory instruments, its target is amateur hobbyists use, like could be a daiwa cn-901….
Comparable to CN901??? What??? Amateur hobbyist use but you’re paying a whole lot of money for it and you should recalibrate it yourslef out of the box???? Sorry but this is bs. I agree 100% with Peter.
@@IZ0MTW Difona sell the LP500 at 949€, the FX773 costs less than half, you didn’t understand what I meant, if you want a nice tool very fast responsive with a lot of features but with the precision like a modern daiwa or similar instruments an FX773 could be you choice, but if you want spend more than double of its price you could obtain for LP500 or used professional millivoltmeters like r&s or hp, about the calibration: you can do it if u want or you can use it as it is with its declared tolerance
@@IZ0MTW Calibration is optional also LP100 can be recalibrated if the sensor is replaced. Nobody forces you to calibrate anything, spend a lot of money maybe you are referring to other products. 430 Euro for a digital wattmeter with 5 "display + 3kWatt sensor including VAT 22% and taxes to date is the lowest price on the web.
I thought the reason I bought it was I was told it was calibrated and accurate. How is average ham gonna calibrate it? That is why they bought it was to measure. As far as being defective should not that have been checked before a professional like Peter get ahold of one? The LP-500 cost more but at least when you do buy it it is accurate.
@@ANTONIOFERRULLI 5” display and you can’t read it. Could be the best bargain out there as you say but 430€ is still a whole lot of money and if I find the unit to have that inaccurate behavior out of the box I’d go mad. A cheap 10 euro multimeter would read voltage stable. Wanna believe that was a defective unit otherwise is just scary
Given that I had difficulty understanding the video in English, in any case the "following problems" emerged, and I'll try to answer point to point: - Small fonts (dBm table menu) answer: the fonts of the numerical values are large, only the descriptions are small (compatibly with the size of the 5 "display) - Voltmeter with 13.1V / 13.3V variation answer: a variation of 0.3V I do not find a problem and in any case in the tolerance of the instrument. - Frequency meter with about 50 / 70Hz error answer: the FX773 does not have an internal thermostated quartz and the accuracy is in line with the tolerance of the instrument.
- Measure power with error about 1.8 / 2 Watt on 3kW full scale response: improved with new calibration from the user menu. - SWR measurement 1: 1.11 / 1: 1.12 / 1: 1.13 answer: the measurements are in real time, no average is applied, and in any case it is negligible as an error. The price range of the Wattmeter is around 300 / 350usd + Vat. Making a comparison with LP500 / R & S (cost about 1200usd + vat) is like comparing apples to pears.

Thank you Antonio, but you are not answering to the most important issue. Why is the power reading so much fluctuating and why is it not possible to reproduce the reading with the next PTT if anything else don't change? According to your SWR statement we don't need to build an average in this test set up as even under real time reading the SWR value should not change connected to a professional Dummy load.
Antonio, I'm not here to talk your product down and you have my respect for your commitment to improve your product! I would really love to recommend your product as it is on a good price point. May be with the next firmware we are very close to what the amateur radio world want...
If someone want to look at my comparison test from FX773 (not recalibrated) vs R&S NRVS URY-Z4 and how it works well i could send the link of the video
Hi, I did not block a video by my self there is an automatic YT container. As I'm already said I'm not here to talk a product down. I'm as you very much interested in facts. Your video which I have released from the YT container has finally made clear that a test value is reproduceable. That is an important fact because a fluctuation in a reading can't get fixed by calibration. So I'm happy to have your video here available. Thank you!
I have to agree Peter for the money they're asking the quality is just not there. The poor user interface and inconsistent readings mean I will never buy one. Their web site is very poor as well. It's a shame as it had potential.
Hi Peter Great videos, very helpful, I also fix radios, I know this meter is not yours , Did your friend get another one ? Was there a fix or outcome to this meter, Thanks Dave 2E0DMB
A great shame, it is too easy with "computer" power meters to indicate too many decimal points when the detector accuracy does not match. My own Arduino power meter has already taught me these lessons! The Telepost will take some catching up to. 73
Watching this video I became more and more convinced that something was very wrong with the design of this unit so I watched another video featuring it. The other unit exhibited the same issues. Not only was the incoming voltage reading fluctuating but also other information on the screen. In the other review the reported temperature varied by over 10c during a 10 minute review. It behaves as though an internal reference voltage is unstable. Unfortunately this is not a prototype, the FX773 is available from a number of outlets here in the UK. It is quite disturbing to see such a poor product being sold and it begs the question why no-one seems to have noticed that it cannot measure any parameter with reasonable accuracy. Peter in your video at least the unit displayed the correct date, I suspect that was the only correct information on the entire display. If a manufacturer cannot spot such glaring defects in their products it is probably a relief that they don't make cars or parachutes....
@@ANTONIOFERRULLI, it is great looking product, it would be fantastic with a little more development. Your website suggests power accuracy as being within 5%, this example is clearly outside of that specification. EDIT Antonio has uploaded a new video, it shows an FX773 and an LP500 with very good correlation. Unfortunately comments are disabled on it so I cannot ask any questions. 73
That is really critical as I thought it is only a fault of this unit but if other units really showing the same fluctuating readings that makes me thinking
Friend of mine has one these and it's a complete pos. Half of the screen went into scrambled garbage. Turned it off and after an hour it came back to normal screen but after 20 minutes the screen scrambled again. Even free I would not have it. Maybe they will work the bugs out in the future.
How is the average ham gonna calibrate it? I think the point was that it is calibrated from the factory. That is why it was bought was to measure. It can't do that right
Thanks TRX lab, a fault perfectly explains the symptoms. Now, if other Metropwr users are seeing similar, wow, I guess I'll steer well away from it & still budget for an LP-100 which I feel is an amazing & well designed/thought out meter. I agree, for older hams & folk with not such great eyesight anymore the screen font sizes are way too small especially when it's likely to be mounted 1-2m away on a bench shelf. The layout reminds me a little of the IC-705/7300/9700 which I have nil issues viewing even in bright sunlight. Thanks for sharing & God bless!
@@TRXLab vom Optischen gut gemacht nur die Software sollte angepasst werden weil das große Display und dann die kleinen Parameter Daten ins Eck rein gepatscht schade aber mit weng was vom LP 100 oder 500 wäre das Teil nicht schlecht !
Sehe ich auch so. Es muss ja nicht so akkurat sein wie ein R&S - aber selbst wenn ich mit einem billigen CB-Gerät ein Signal produziere, sollte dessen Leistung zumindest immer gleich angezeigt sein. Leistungsanzeigen a la Zufallszahlengenerator kann ich nicht gebrauchen. Gleiches gilt auch für die Spannungsanzeige.
It would be better to reduce the digits on the screen as they pretend to be a very accurate meter..It is more important to see on which frequency you are in general
I've never seen that meter before but judging by the cluttered screen layout, small font sizes and general lack of attention to detail, I'd say this is just some cheap Chinese meter. Probably uses low resolution ADCs. I'd take the LP500 any day instead of that! 👍
na ja 450€ ist eine Menge Geld und dafür möchte man sich auf ein Gerät verlassen können. Natürlich können solche Geräte nie gegen proffesionelle Messgeräte antreten..
Also bei einer konstant gleich bleibenden Leistung so springende Anzeigen und Abweichungen von mehr als 2 Watt? Das macht ja jedes CB-Messgerät besser. Entweder das Teil auf der Bank hatte ´nen gewaltigen Schuss oder das Preis-/Leistungsverhältnis des FX773 ist unter aller Sau. Für mich gegenwärtig kein Kauf.
Hello all hams.I think this test by peter is a little unfair.First of all you can not compare a swr meter with lab equipent worth 100 thosends and second he did not show how you connected the unit to a computer screen yes most hams today have a computer for logging and other software.And third he did nor show you the page in the meter were you can calibrate swr voltage freq mm so that is why i think itis litte unfar.
Lennart I don't agree as I have not compared it with lab equipment. I used the R&S for reference to have something accurate to be able to build a up a valid statement. We all know that it would be unfair trying to compare lab equipment with amateur stuff. That was never meant
You seem to have calibrated everything except the FX773 ! There is a calibration menu to fine tune the FX773. It would then mirror the output from your fine-tuned test equipment

was kann man für rund 600EUR verlangen - es ist nun mal kein RACAL . . .
na ja 450€ ist eine Menge Geld und dafür möchte man sich auf ein Gerät verlassen können. Natürlich können solche Geräte nie gegen proffesionelle Messgeräte antreten..
Also bei einer konstant gleich bleibenden Leistung so springende Anzeigen und Abweichungen von mehr als 2 Watt? Das macht ja jedes CB-Messgerät besser. Entweder das Teil auf der Bank hatte ´nen gewaltigen Schuss oder das Preis-/Leistungsverhältnis des FX773 ist unter aller Sau. Für mich gegenwärtig kein Kauf.
1200 euro for the lp500,lots off money for a poor ham
That is true
Hello all hams.I think this test by peter is a little unfair.First of all you can not compare a swr meter with lab equipent worth 100 thosends and second he did not show how you connected the unit to a computer screen yes most hams today have a computer for logging and other software.And third he did nor show you the page in the meter were you can calibrate swr voltage freq mm so that is why i think itis litte unfar.
Lennart I don't agree as I have not compared it with lab equipment. I used the R&S for reference to have something accurate to be able to build a up a valid statement. We all know that it would be unfair trying to compare lab equipment with amateur stuff. That was never meant
This instrument is not for real users, crap!!
Thanks Peter.
looks like
Swing and a miss
Seems like a piece of rubbish. And, by the way, "anyway" is always singular.
Thank you we never stop learning
Correct, but it´s his station identifier ;-)
