Your HV warnings are spot on...hams today who want to experience the boat anchor days have to be very careful. I was building a Novice transmitter in high school electronics shop and one day got across the B+ and found myself half-way across the room; one hand in back pocket rule learned the hard way! And the MOX "fault" has caught me at least once myself when working on both tube and solid state HF rigs. A tech who admits their mistakes is ok in my book, good job Stefan! 73 - Dino KLØS (PS - in the U.S. Army it was RTFM, you can imagine the letter meanings!)
Stefan, I have been learning how to use the FT-101zd I got from my father just before he died. I got a good EE to look it over. He recapped and aligned it. Another EE friend, recently a SK, taught me how to tune it. I normally use an FT-891 in my station. I am learning CW and want to use the FT-101 for it. Your example of tuning the transceiver has helped me understand the manual much better. I am keen to watch your video on the details of tuning the rig. Thank you. Bob KA6REL
Excellent video. Informative and educational. The details of isolating voltage and earthing the PA circuits particularly useful and something in over 50 years of working on radio equipment I have not come across. Al GM4ENF.
Thank you very much for this video I enjoyed it very much. I have just acquired the MKiii version of this and it still catches me out sometimes and as you say read read read the manual and practice.
Good video. To quote two Korean Drs after they made a mistake “even the monkeys fall out of the trees”. I have a 101zd and a 901dm. I enjoyed Your video, thanks, W7gnv
Page 14 of the OM speaks to the Proc & Drive interaction. Interesting and unexpected. RTFM. I did see some nice tips in this vid. Never thought of using a tube to isolate a removed wire. 👍
Good day. Very interesting video. The processor on my 101zD does not work. It’s not this problem though. More importantly the CW transmit seems to only give me a full key down when I am sending CW or trying to like something is stuck. Radio loads up fine and output power is good. SSB works fine ( except processor and I can live with that )
Those voltages make me very nervous. When I was at university, I saw the result of an electrocution when doing vacation work. I’ve never forgotten the scene, and gained a real respect for HV … actually not really respect. More like fear 😊
Yes, it has a power output settable down to nearly zero. But to achieve constant and non drifting 10W in SSB and CW, this unit isn´t designed for! The output will vary with temperature of the components, so you have to measure and control the output permanently. The ALC is set to 100W, with 10W you are below the ALC threshold and have no stabilisation.
Hello Stefan, Thank you for this nice video. I have an FT-101ZD since 1985. What I see in this moment, it some small frequency shifting of the VFO which is unstable even after 30 minutes warm up. It desappears when I push one time from the VFO to the CH1 switch for example (switch bloc located under the VFO). Did you already hear about this unstable frequency on the FT-101ZD ? It seems that this issue is known..... Thanks a lot. 73's. Stephane.
@@dl7majstefan753 Yes, I also assume it. Because the switch connects only the 6V to the VFO, if I'm right. I have tried to spray TUNER contact product into the switch but I am not sure that the product goes completely into the switch. The best would be to check the 6V after the switch when it happens...... I keep you informed...🙂 Stephane.
Hello Stefan, just to keep you informed or others OM's who could have the same issue.... I checked the VFO output and sometimes, the level and frequency were jumping...I have re-soldered the main points on the VFO PCB are the VFO became very stable since a few days now... I hope that it will stay as it is 😀- Kind 73's. Stephane (FR) . Thanks again for great videos!
@@stephane-710 Hello Stephane, yes, the problem of bad solder connections is known - not only for this YAESU rig, also kenwood suffers this topic. Tnx!
Hi Stefan, I am new on old radios restoring and I am thinking about to be a radio amateur also. Do you think that a Yaesu Ft-101 Mk1 could be a good start? There is one on sale here in Brazil at 1.000 Euros. What do you think? Thanks.
Don´t know the price level in Brazil, but 1000,.- are definitely too much! Depending upon condition and extras (CW-filter?), i wouldn´t pay more than 300,- to 400,- for it. Don´t forget: Old equipment, old tubes, etc ...
@@dl7majstefan753 Many thanks Stefan. I will think twice before the acquisition of an old equipment like that. I will keep following your channel and will make my mind about a more modern transceiver. The prices in Brazil are always much more than in Europe or North America. The taxes for electronic imports were always sky high (and we were a much poorer country back then, not too many people to make an acquisition like that). Nowadays, the taxes for the electronics goods are around 100%, including the cost of the shipment...
@@rádiosantigos1958 Ah! OK, understood. So we have here a bigger EU market including also US market (+VAT 19% only for electronic imports). Hope you find a good TRX.
Hallo Stefan. Ich habe einen 101z mit nachgerüstetem Zähler vom Vorbesitzer. Leider ist der Zähler so angekoppelt, dass er bei ssb nicht die Kernfrequenz zeigt. Das Gerät war vormals nur im cw Einsatz. Dazu wollte er diese Anzeige so haben. Für ssb untragbar. Kannst Du helfen? Interesse hätte ich auch an einem 902dm. 73 DL6NLI WIELAND
Hallo Wieland, welche Frequenz zeigt denn der Zähler bei SSB, also USB und LSB an? Ist es die Frequenz des unterdrückten Trägers? Das wäre üblich - also immer ein Versatz von ca. +/- 1,5kHz zum SSB-Signal.
@@dl7majstefan753 Hallo Stefan. Danke für Deine schnelle Antwort. hier was er anzeigt in der jeweiligen Schaltetstellung: AM 14.100.0 CWN 14.100.0 CWW 14.100.0 TUNE 14.100.0 USB 14.102.3/4 spingt zwischen 3 u 4 LSB 14.099.3/4 "
@@wielandfischer5851 Die Differenz zwischen USB und LSB ist fast exakt 3kHz (+/- 1,5kHz); ich hätte nur erwartet, dass er bei LSB die höhere Trägerfrequenz und bei USB die geringerer Trägerfrequenz anzeigt. Irgendwie scheint da die Erfassung der BFO-Frequenz und deren Abgleich nicht zu stimmen. Auch ist verdächtig, dass bei CW exakt14.000.0 angezeigt wird. Irgendwie scheint sich der Vorbesitzer da etwas zurecht gebogen zu haben....
@@dl7majstefan753 ja, laut seiner Aussage damals in den späten 80ern wollte er die tatsächliche Sendefrequenz angezeigt haben. ..."man müsse den Zähler nur anders ankoppeln" meinte er damals. Ich habe die Anzeige damals nicht genutzt, da mein Transverter einen eigenen Zähler hatte. Die 1400000hab ich auf cw eingestellt und dann durchgeschalten. Möcht den halt nun gerne für KW nutzen. 73 DL6NLI
@@wielandfischer5851 Hallo Wieland, da kann ich Dir leider aus der Ferne nicht helfen. Als Projekt für meinen Kanal ist so ein Gerät ungeeignet, weil ich aus Erfahrung sagen kann, dass diese oft stark verbastelt sind und ohne Dokumentation der Änderungen den Aufwand für eine Restauration nicht lohnen - sri. So etwas endet im Frust.
