Re: CAT update blocked during TX
Peter: This behavior for several Yaesu radios (857, 817, 897) is mentioned in the SatPC32 documentation.? (Hints->Yaesu, see the Reame(Yaesu).txt file).? Manual tuning (front panel) works, but CAT-controlled Doppler correction disabled when PTT pressed. Recommendation is to keep transmissions short, especially when Doppler shift changing rapidly.

Re: CAT update blocked during TX
Hello Yono,
I tried it here, and indeed, the 857 will not accept frequency change commands by CAT during transmit. I am pretty sure the CAT interface itself functions, as I use CAT command to switch between transmit and receive. So I guess it is designed this way. 73 Peter/PA3FQH |

CAT update blocked during TX
Dear all,
While qso with a friend that uses a FT-857 thru a linear satellite, I noticed he always drifts upwards. He said GQRX was not updating the freq while TX and he has to release the PTT button between syllables so the radio catches up. Is this a known bug (CAT port is disabled during TX), or the CT-62 cable got RF interference during TX. Let me know your thoughts, 73 de Yono - YD0NXX |

Quickly change power levels
Michael Dannhardt
Hi. My Dad has a FT-857d and has recently installed an external amplifier which needs a drive level of around 20W. So we are looking for a convient? (fast) way to switch the rig from full power out (100w) to a lower level.
I thought the A/B stacked VFO would work but it doesn't seem to save the power level per VFO. Any ideas? FWIW - he has the fancy mic with all the buttons. Tnxs for any thoughts, Mike / KA4CDN |

I must be losing my mind.... I've got this thread being started by VK2DHV (who according to the ACMA database is David). All good - Stay safe. Cameron?

Re: Another newbie question - programming frequencies
I guess I was just commenting that you can store any frequency in memory via CHIRP. If the radio is receive-only on non-ham frequencies, it will still store it but for receive only. If you do the all-frequency transmit mod, it's your responsibility to not transmit on unauthorized frequencies. But there are uses for this mod. I have a couple VHF transverters that use oddball IF's outside a ham band. I can attenuate the transmit power to what is needed for the transverter. 73, Zack W9SZ On Wed, Jul 7, 2021 at 9:39 AM Cameron McKay <cjmckay@...> wrote:

? This legal situation is actually much more onerous than it appears on the surface - hence why my response included specific reference to the Act (an Australian legislative document found https://www.legislation.gov.au/Details/C2021C00046) and the applicable clauses.? Even being in possession, especially if the rig was made capable of transmission on those frequencies (even if only programmed as 'receive only') would like be deemed as 'with intent to operate'. If the radio was found to be functional (and especially given that the question has been asked in a pseudo-public forum) then there would be little in the way of a 'defence' (I can think of one but I'm not placing it into the public domain).? This is a specific issue I have asked our National Representative Body to have addressed in future revisions of the legislative instruments. 73, Cameron

Re: FT-857 power connector
I don't understand how the plug that came with the FT857 and two others on cables I have purchased elsewhere can all have faults. As I mentioned, all these plugs fit just fine on the FT897D and the Kenwood TS850SAT I have but none of them fully seat in the connector on the FT857D. I would have to assume a fault with the FT857D connector. I don't know what the problem is, though. What I ended up doing was unsoldering the power cable inside the FT857D and replacing it with another 3 foot length of # 12 gauge cable pair (with red and black insulation). I did this because, if I choose to sell the radio at some time, I want to be able to restore it to its original state as I got it. I put an automotive fuse holder with a 30A fuse in each lead. I put an Anderson Powerpole on the other end (which is what I wanted in the first place). It works fine. Voltage drop displayed by the radio is about 0.2 volts under hard key-down under full power. This is acceptable to me. It was recommended that I do not use a soldering gun with a loop-type heating element because it produces magnetic fields that could affect components in the radio. I have a Weller GT soldering gun that does not produce magnetic fields. It is a 150W soldering gun with a ceramic type heating element. I have used it to solder pipe cap filters onto pc boards. 73, Zack W9SZ On Tue, Jul 6, 2021 at 1:10 PM VA7OTC John Erskine <va7otc@...> wrote: On 2021-06-27 07:13, Zack Widup wrote: |

Re: Another newbie question - programming frequencies
Thanks everyone. There is no value in me doing this if I can't transmit and receive on those frequencies.
I understood that in an "emergency" situation (which in reality is the only time I would do this) all the normal constraints like type approval went out the window? |

Re: Another newbie question - programming frequencies
¿ªÔÆÌåÓýHi Zack, ? Agreed, however, Stewart was also mentioning about transmitting using the radio hence Compton¡¯s, and my, comments about its none type approval here in Australia. One of the requirements for type approval here for non amateur band equipment is that it not be programmable, on transmit, from the front panel. ? 73¡.Eric VK2VE. ?

Yes, but if he wants to listen to various frequencies? without having to tune to them each time, the rig will accept any frequency in its range for receive only. I am never going to transmit on LF NDB frequencies or AM BCB frequencies, but I have quite a few of those programmed into the radio with CHIRP. ? 73, Zack W9SZ ?
