Yaesu FT-790RII 70cm radio way off frequency.

[@boldford]

The mono-band ham transceivers were, in many ways, far better than many of the modern rigs that operate between DC and daylight.

JP3 had glue on the connector. Nice job. Thanks sir.

[@jeffadams5510]

Sure do still miss ya on here Mike!!!!!!!!

[@BoB4jjjjs]

That had been a nice little set in its day. I would have liked to see you work a bit more on it, but then most maybe wouldn't as it takes a long time and it also slows you down a lot. Thanks for showing us the radio and explaining what you had to do to it.

[@thestranger2749]

Yeah you know those caps were probably getting dried out. But having two boards in that thing would have made a capacitor replacement a very expensive job for the customer and a very slow process for mike.

[@BoB4jjjjs]

@@thestranger2749 Yes, they are not cheap these days, but the little is!

[@thestranger2749]

@@BoB4jjjjs I can only imagine that in the future cheap surface mount boards will be the only boards that exist. It's going to be practically pointless to work on surface mount stuff, no one will pay you to repair it when they can just go out and buy another. Hopefully people in the CB and ham community will keep through hole boards alive. I know I'm keeping my CB collection for the rest of my days. Just think, in the future we'll have to explain to the new generation of illiterate thumbsuckers that people used to be smart enough to repair their own devices. They'll say "What a stupid imagination grandpa has"

[@BoB4jjjjs]

@@thestranger2749 Ham gear will always be repaired, it is just to expensive at the moment to throw away, except Chinese hand held sets. I would repair my own CB even if it were surface mount devices, but I am just like that, I just don't throw anything out that will fix. If it does not fix or not worth fixing, bits are taken off, and it gets the heave. They are trying to reduce waste, but really, it can cost more to repair something these days than buy a new one. The cost of parts is bad enough (if you can get any) but the amount they charge for labour!!!!

[@thestranger2749]

@@BoB4jjjjs Seems like skilled repair technicians are becoming a rare breed. With all the expensive proprietary parts and Apple threatening to sue every time you fix one of their devices no wonder repair costs have gone up. I'm trying to fix a CB I picked up yesterday, it's a sidebander with no modulation. I'm currently checking for shorted capacitors around the AF amplifier, the caps definitely needed to be changed, considering they are over 30 years old. So far no luck, and I'm looking forward to getting a signal tracer shipped in to save myself some sanity. Sure I could throw it away, but thats not very fun.

Whats ur opinion . Atv==> transmitt/reciever radio antenna. 109 stainless whip that csn take a beating or a fiberglass 3 footer with load that cant take vibrations let alone smacking a tree limb. No I did not answer myself, because that wipe hits airplanes lol. And in the heavy woods I need to tx/receive. Better. Dose a whip transmit from the bottom of the antenna?

[@skipperskipper2936]

Could you modify every female connector to out side horizontally with case.? Objective is to stop breaking off circuit board. / make damage out side where it can be seen& fixed quickly. I hate these jacks. Only problem I ever have in anything is those dam jacks. (Hard wire to outside radio case.)

[@twoheart7813]

I've got an old ic-3220 that is 3kc off and I can't get it to adjust any closer to real freq adjusting the reference freq for that band so figure caps have changed value in the circuit.

[@jonka1]

Please update us on what happened to the severe drifting after your alignment.

[@mikesradiorepair]

It still drifts. That's the nature of the radio. That's why you have to wait 15 to 30 minutes for radios to warm up before alignment. You need to let oscillator circuits stabilize.

Hi I have a yeasuft840 and it's off frequency let's say I want to transmit on 27.385 I have to tune it to 27.384.76 could you help 73s from Trinidad.

[@mikesradiorepair]

Perform a transceiver alignment as documented in the service manual linked here: www.radiomanual.info/schemi/YAESU_HF/FT-840_serv.pdf

Thanks for the new videos! Oh by the way I'm not one of those bots! LOL Here's the weird part, I only got notified you had just posted only 3 new videos! HMMMMM!

[@samiam5557]

nice old rig

[@w.rustylane5650]

They use a BNC connector for the antenna?

[@loctite222ms]

Doesn't have the amplifier section on the back.

[@skipperskipper2936]

Why cant I buy a Quality radio that will be water proff shock proff that transmits & recieves 50 miles strsight line unobstructed ? Turn it on and press talk. Absolutely no buttons switches gagits chrome lipstick sex etc. Jjust a useful piece of equipment that stays out of the repair shop.

[@loctite222ms]

Let's take the example of using a hand held radio at both ends of the path. Antenna is about five feet of the ground, line of sight propagation is around five miles. Even TV stations with tens of kilowatts of power and tall antennas often are hard to receive 75-100 miles away. Find a loophole in the physics and you can build your radio... I can talk to people across the sound in long Island with maybe 5-25 watts, but I'm about 400 feet above sea level and from the top of my TV tower I can SEE Long Island.
