Thank you Sir, I have received my 2955 (30watt in) back yesterday. Only 3 of self test passed before, now all passes. I am so great full for Deon (rf engineer with 2 BSc degrees) that fixed it for me. I am back fixing cb radios again. Thanks for your video it helped a lot.
@@TonyAlbus Hi Tony, I also used to work with them around 25 years ago and that's what kept me interested. I have repaired a number of 2955s over the years as they are very serviceable. Keep up the good work I am looking forward to your up and coming videos.
Hi Tony, Just bought one of these for aligning CB Radios . I was lucky to get it with a brand new screen fitted. Just now getting to know it. Your explanation is very good Thank you
SSB ON YOUR 2955, Hi Today i got a mini-circuits SBL-1 Frequency mixer and have wired the IF out of the mixer to the AF input of the 2955 test set, and setting the test set sig gen to 0DBM output on the bnc to the LO in on the mixer and the ssb radio to the rf in on the mixer using a power tap/ attenuator so you don't overdrive the mixer, set the test set/ signal gen to the same frequency as the radio is set to,with the modulation on the signal gen switched off, you can now hear your SSB audio clear and also use the 0-scope on the test set, You don't need a test set to do this only a audio amplifier, and a signal gen, but i wanted to use my 2955 to hear my SSB signal, without switching on another radio or RX, I got this Idea from Peter TRX LAB on youtube, as he made a SSB Monitor , yes they are long videos but he is very interesting Thanks Dave 2E0DMB
@@TonyAlbus yes looking into it it is a nice project to try. I did buy a 2955 so within a week or so will have one here. This is just for my radio bench but do hope to keep it working properly.
It is a property of sticker i think, the guy in the parking lot said it was no problem, then he quickly drove off with his old BMW, it is prob. fine :)))
Hi Tony, Very interesting vidoe indeed! I have one of these sets but unfortunatly it has a lot of problms because all of the self tests fail! it also needed a replacement 10MHZ standard to even iniitiialize. I am determined to fix it though I hope that none of the problems relate to any philips hybrid devices! OM345 , etc.
Hi Mich, yes first the 10MHz, the whole system runs on it, i have even heared stories of people corrupting the memory becouse of unstable 10MHz. for the OM345 are replacemnets kits with MAR-3SM OpAmps that are also reaseneble flat in that range. i hope the 10MHz is already good for you to fix it, but just that you know its not lost if you need OM345
achter mijn gosdo heb ik de bg7tbl distributie FDIS-5. deze heeft 1, 5 en 10 mhz. ik heb er wel een paar videos van. in de omschrijving vind je de items
Hi Tony, Ik zag hem natuurlijk al in elke video maar die Marconi tester is echt een bijzonder stuk equipment. Als radio amateur zal het vast je trots zijn. Ik vermoed ook zomaar dat dit destijds een kostbaar apparaat was. Ben zelf geen radioamateur maar vind het wel interessant om te volgen. Hij zal vast vaker figureren in je video's ;-)
Hallo Marcel, Bedankt voor je bericht, zeker ben ik er trots op, ik heb hem vorig jaar aangeschaft via marktplaats.. 200KM ver weg, maar de volgende dag stond ik voor de deur... ik heb er 25 jaar geleden professioneel mee gewerkt en sinds dien op zoek, het vinden is al lastig(niemand doet hem weg), maar de prijs ook.. die ik vorig jaar vond, was netjes en goed en de prijs ook, dus meteen geregeld. aardige verkoper ook. je zeker voor de zendammateur een heeel leuk speeltje. toen ter tijd nieuw kan je er een auto van komen denk ik, maar dat is wel 30-40 jaar terug.
@@TonyAlbus haha, ja dat dacht ik al. Maar ja, spreekwoord is nog steeds: goed gereedschap is het halve werk:) In welk gedeelte van het land woon je? Ik in NH, even boven H’lem
@@malster181 They are CB from the 80, but in The Netherlands they are/were FM... CB is now more active again and now is also allowed AM and SSB, but in that time it was only FM
I had one in my shop during the infancy of AMPS cellular phones. It was a great monitor but every other tech in my region used Cushman, IFR and Motorola. The AMPS option soon went by the wayside with the onset of CDMA and TDMA digital cellular.
Yes the start of cellular.. actualy just before :) .. yes i used that too, but mostly for Taxis and Construction sites who still use Walky Talky ..but professional.. fun to work with it then 25 years ago, fun to have it now as a hobby :))
Hi, yes I was struggling with that too. you have to set the modulation to 50% and then confirm with AM Hola, sí, yo también estaba luchando con eso. tienes que configurar la modulación al 50% y luego confirmar con AM

Yeah!! great to hear that, yes it is an amazing machine.. congrats!!
The 2955 is really useful bit of kit I'm glad to see that you are enjoying it. Keep up the good work.
Thank you John... yes have worked with it 25 years ago, i started looking for it sins i left that job.. last year i got lucky and found it :)

@@M0XFXUK Thanks you very much! and i hope mine does not need repairs any time soon :)))
Hi Tony,
Just bought one of these for aligning CB Radios . I was lucky to get it with a brand new screen fitted. Just now getting to know it. Your explanation is very good Thank you
Hello Nigel, that is amazing, congratulations!.. may you have lots of fun with it, thanks for sharing!.
looking for a backup service monitor. how does the marconi compare to the hp 8921a?
Hi, i like the Marconi a lot but have no experiance with the HP
SSB ON YOUR 2955, Hi Today i got a mini-circuits SBL-1 Frequency mixer and have wired the IF out of the mixer to the AF input of the 2955 test set, and setting the test set sig gen to 0DBM output on the bnc to the LO in on the mixer and the ssb radio to the rf in on the mixer using a power tap/ attenuator so you don't overdrive the mixer, set the test set/ signal gen to the same frequency as the radio is set to,with the modulation on the signal gen switched off, you can now hear your SSB audio clear and also use the 0-scope on the test set,
You don't need a test set to do this only a audio amplifier, and a signal gen, but i wanted to use my 2955 to hear my SSB signal, without switching on another radio or RX,
I got this Idea from Peter TRX LAB on youtube, as he made a SSB Monitor , yes they are long videos but he is very interesting
Thanks Dave 2E0DMB
Thank you David, that is indeed very interesting, great you got it to work also, i will have a look at Peters video about this. Great Tip! thanks!
Hi Tony, seeing your 2955 has me looking at them, have you seen the LCD upgrade?
Yes i have, but will only do it if needed to keep my Marconi alive.. it is not cheep also
@@TonyAlbus yes looking into it it is a nice project to try. I did buy a 2955 so within a week or so will have one here. This is just for my radio bench but do hope to keep it working properly.
@@jimwolsiffer4397 Nice catch!
Now you got me wondering what the blacked out label/plate is on the top center of your Marconi...?
It is a property of sticker i think, the guy in the parking lot said it was no problem, then he quickly drove off with his old BMW, it is prob. fine :)))

Good show Tony, but probably better to check and AM radio with 2955 set to AM modulation not FM..
Yes AM radios check on AM setting and FM radios on FM, these are FM radios. thank you for your question.
Ah ok, they are the 10m rigs. All good.. Great vid

Hola buenas tardes,en RX.
Como se hace para hacer
Cambio de AM A FM
En rx no responde en tx
Si normal!!
Saludos cordiales
Gracias!!

Hi..nice video...
do you have a b&K 1040? If so could you show us how to do a two-tone test within oscilloscope ??
Hello Kevin, i have not a B&K , i only have the Marconi as a test-set.. i checked, the B&K looks nice too!
tony,,how do you do the self test,,checking for errors ? thanks
Hi Dennis, [HELP], select [Change parameter], then [TX], now the SELF TEST menu is displayed.
@@TonyAlbus thanks,,have one coming wednesday
