Re: Another look at the Yaesu FT 857D
I follow several groups and when I see the same name, title, wording and links I tend to think that they are spam. When I say the same, I literally mean word for word. 73, Joe / AJ3O

Same here. I turn it on and the most I have to do is change frequency and hit the tune button when on HF. I haven't seen the video yet so I don't know what it says, but once the 857 is set up, it's pretty much turn it on, go to frequency, hit tune (if on hf), and enjoy nice QSO's. 73, --Hank KB4MTO / TA5ZC https://www.hamradio.hanklambert.com ---

Amateur radio, which is also known as ham radio, is a popular hobby worldwide, but choosing the perfect model for your needs can often seem impossible. You typically need to try out a radio so that you can get an idea of whether or not it’s worth your money, but we’re going to try and do the next best thing.

In this article, we’re going to present our in-depth review of the FT-857D from Yaesu, so you can figure out whether or not it will get the job done.

Replacement of 2sc5374 50mhz pre rx
i suspect that I have the problem of low sensivity in rx in 50 mhz band. I tried to order one 2sc5374 transistor q3034, in the usual sites of electronic components ( mouser, digikey, etc. ) but it appears as a obsolete part.
Any other cross reference as replacement? Or, I find in ebay sellers that have this part in stock, but it can be are "fiable" original parts? 73S |

开云体育Im confused. I turn mine on, its on the last freq, mode,power, etc that I used. Change bands, same thing.?? , what checklist are you talking about? Can you clarify your comment?

Re: no AM TX

[Edited Message Follows] TNX for the ideas so far.Even in the lowest setting there must be some TX output to be measured by a power meter. That's not the cause. I already went through all menu settings. Meanwhile I found out there must be some mW output which my power meter does not display. With another RX I can detect a carrier and hear the modulation. May there be a problem with the ALC? The meter doesn't show any ALC on AM but on FM.? I think on AM there also should be almost some ALC be displayed. Could anyone please verify this? 73, Michael |
Re: Zebra Stripes fixed in my 857D
No improvement. I'm going to try one more technique using a soldering iron. meanwhile, the replacement I ordered from Radioworld in the UK is "dispatched" to quote them! This was a very good deal as i stated before due to current exchange rates. I fear these displays will become scarce soon. Sending the display back to Yaesu for repair would likely have cost double what I paid factoring in including shipping each way to Yaesu. The link to the replacement is in my previous post - I'll let all know how that turns out.

Re: problem with pkt mode in 9600 baud
I have one variant similar to signalink. Is a Cat/data interface Sm4xiu.?
Yes, is a possiblity that the isolation transformers, can be a source of problems. But now I jumpered it. I have made new tests, and I obtained connections ok, at speed of 7200 bauds in the UZ7HO highspeed sound modem ( with the rig in 9600 mode ). But no at 9600.?
I have good rx, but no TX.
?
Caution: the 857 rig have two rx outputs in pkt mode: One pin? for rx in 1200 and other pin rx pin 9600, in data connector. And only one pin for tx in 9600 and 1200. Yes I put a swtich for switching audio 9k6 to 1k2.
?
I suspect that the problem is that my usb sound cards (? I? am trying two models ) have a line level output sufficient for 1k2, but? with very low level of signal for 9k6. In fact one of the two have a little more high level than the other.
?
I see in the rig with mod indicator at the display, the better sound card, only comes to 1/4 of the modulation scale of the meter.?
?
Looking the cat port radio specs. I see the tx input of the rig, have a signal of 1Vpp 10k Zin. I suspect that in general the usb sound cards line level don't have this level of signal. I will measure later, with a oscilloscope the level of signals.
?
If this suspect is correct I will contruct a little preamplifer for example with operational amplifer ( non inverter amplifier with single power supply with variable gain).?
