Re: PAT board and FT818

 

Hi Dick
Thanks for help.
I did some search over the internet, but didn't get across this page. One thing that didn't came across my mind yesterday, was that you can calculate new values by multiplying lpf component values with freq(a)/freq(b). Thus the multiplier in this case is 50/75=0.67
The page you linked verifies that i am on the ballpark with calculations.

Re: Power bank questions

 

I have a 12V 24 aH (13.8V 24,000 maH) LiFePo as the largest practical size pack. I have two sets of Anderson Power Poles for 12V gear and two 12V to USB-C plug 5V 3A step-down inverters (for raspberry Pi + QHD screen or whatever). I got it to power my FTdx10, but of course it's fine for my FT817ND (and optionally PAs). It's charged by 2 x "100 W" solar panels easy enough to put in a small car. I mean to get a car charger and mains charger. The MPPT controller is a Victron (cheap model with no BT, so I had to interface the TTL serial to change it from Lead Acid to LiFePO4.)

Lives in a carry-case with shoulder strap along with LED meters.

The LiFePO4 has 3000+ full cycles rating (down to 10%) and a 1/3rd of weight of Lead Acid. Safer than LiPoly/LiIon. The cheap Lead Acid Gel / SLA for emergency backup (UPS, lights, Alarms) don't even quote cycles. The more expensive ones (more expensive now than LiFePO4) are about 100 to 200 cycles, but only if not fully discharged. The 200 cycles is about 70% usage.


Re: Power bank questions

 

Also, note - the power bank you linked to claims 20,000 mA, but at what voltage? I suspect at 3.7 volts, the voltage of the internal cells - 20,000 mA at 3.7 volts will be closer to 5,000 - 6,000 mA at 12 volts, maybe less. That may or may not meet your needs - that is something to consider when choosing power source.

?I’d stick with a 12 volt lifepo4 battery and use converters to power/charge 5 volt usb devices. I recently added the Windcamp battery kit?designed for the 817/818, it’s about $75. Also 3 18650 batteries in a 3 battery case work well and can be recharged with a 4 cell charger. Don’t risk messing with alternative power sources.?

The connected device controls the output voltage, you would use a cable configured to "tell" the power bank to supply it with 12v.

I don't think anything 'guarantees' the power bank won't provide a different voltage, just the presumption/expectation that the devices will work as designed.

To power an FT-817 type of radio with 12 volts, you would use a cable designed to priced the desired voltage, like this:

Re: Power bank questions

 

One more thing regarding USB-C: , for instance, states outputs of 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A. What does garantee it will output the 12V the FT-817ND needs and not the 15V or 20V and fry the radio?

Hi guys:

I have a question about my ft817.

Yesterday, I was on 28336 on ten meter usb mode.

When I attempted to answer a buddy, and I key up the mic,

The frequency would shift upwards to transmit on 283445.

I looked up the menus to see if repeater shift was on, and I got the following:

?

Menu Item 42 [RPT SHIFT]

Function: Set the magnitude of the Repeater Shift.

Available Values: 0 ~ 99.99 MHz

Default: Depends on transceiver version, and the band in use.

Each band’s repeater shift (HF/50/144/430 MHz) may be set independently.

?

The thing is, when I enter menu 42 and turn the tuning knob to the left to try to get it to 0, then hit hold the function button to get out of the menu,

The voice box I have reports nothing.

Has anyone else ever encountered this problem?

?

Please advise as you like.

Hi there:

First, I have tried on other bands and do not get the split; it is only on ten meters.

Second on ten meters whether cw or phone, it moves up by nearly 9 khz.

Again, on other bands, whether cw or phone, it stays on same frequency.

Hi Mike,

?

That doesn’t sound like a repeater shift problem as repeater shift is only operational on FM.

?

The shift is only 8.5 kHz so it may, in fact be that the radio is in split mode. Try changing your receive frequency to, say 28.340 and then see what the transmit frequency does when you transmit.

?

Also, see if you get the same sort of result on other bands.

?

I have an FT857 which has a fault (which I haven’t yet fully diagnosed) whereby it transmits 13 kHz away from the receive frequency. This occurs on all bands and modes.

?

Let us know the results of those tests and we can try to diagnose further.

?

Thanks everyone for your advice. I will do as K6AEF suggested and advertise the radio and filters together in the first instance.

Re: Advice on selling

 

I would suggest putting the rig up for a fair price which includes the filters in the sale. Likely someone will be very excited to purchase the rig with those filters.
?
If someone wanted to buy the rig and wasn't interested in the filters then you could sell it to them at a reduced price and remove the filters to sell separately.
?
If I didn't already have an 817 and hadn't modded with the SotaBeams chip I would jump at the chance to buy your rig with the filters installed.


Re: Advice on selling

 

It may make it easier to sell and to get a bit more for it. What would you do with them if you pulled them out??? Sell them? Use them?
