radio is weird

 

开云体育

Hi guys:

?

Before I send my radio off to Yaesu, I thought I’d run the problem by the group.

?

My radio shows running all modes on each of the top buttons. In other words, instead on selecting the bands, all buttons do the modes. I’m sorry that I cannot put this in a simpler text. I did a total reset, but to no avail.

?

I believe it is a problem with the processor. I do not know how to get into the hidden menu and would like to avoid that. I would be willing to do that if someone would show me how.

?

Any ideas?

?

Thanks.

Re: ACC and DATA plugs for FT-818?

I used a similar connector (forget where I got it) and simply didn't push the outer cover all the way up to the end.? Ran some tape around the outside to keep it from moving, and it's worked ok in my 818 since.? I think the use of some heat shrink tubing (the kind with glue on the inside) might be better than the tape.

Does anyone have a preferred source for plugs, or for plugs with integrated shielded cables, to fit the ACC and DATA jacks on the FT-818?

I discovered on Friday that the plugs sold by the local Sayal Electronics store (from Mode Electronics) have outer shells that are too large in diameter to fit in the recesses in the rear panel of my FT-818.? These appear to be identical to this more widely available plug, which apparently fits the FT-817 but would certainly not work with my FT-818:



I managed to make the Sayal/Mode plug fit, since I had no time before the Microwave Sprint to procure an alternative, by whittling down the outer plastic shell, but it was rather tedious work!? The shell diameter on the Sayal/Mode connectors is 14.1 mm (0.555" - measured by me, 0.551" per the Digi-Key-linked datasheet) and I measured the chassis hole diameter at 12.9 mm (0.508").??

From photos I found on the web it looks like there was a change of the rear panel casting from the 817 to the 817ND, but the pictures of the 817ND and 818 look the same.

Suggestions?

Re: Power pole adapter

 

Hi all,

A number of you who own our Kx33 power supply asked us for this adapter for use with the stock Yaesu charger, so we are now stocking a 4.0mm x 1.7mm female DC power jack to Anderson PowerPole adapter.? You can find it on our website here:



And to also answer the queries, yes we are still running the group special of a Kx33 Low-RFI power supply plus the proper adapter at no extra charge.? It must be ordered through this link:



I hope to meets some of you at Xenia, we will be in booth 1610. We now return you to your non-commercial content, undoubtedly in progress...

Hi Randy:

Nice find! ? However, the barrel connector is not the size for the FT-817. ? Works with many other rigs, however.

Re: FT-818ND new UHF filter performance?

 

FYI

HobbyPCB makes low-cost filters for the 144, 220 and 440MHz bands. They aren't anywhere near as high performance as the OCI cavity filters but they are only $20 each, handle 10W, have low insertion loss and can greatly improve the FT-818's ability to reject out-of-band signals.

File - FT817 Group Guidelines.txt

 

The FT817 Group averages over 500 (+/-130 one-sigma) messages
per month. Because the volume of messages is rather large, I would
like to remind everyone of a few long-standing FT817 guidelines to
follow. Most of you do so already.

1. Civility. (This is practiced well by our members!)

2. Please sign your messages with name and call sign, e.g.,
Fred - W1XYZ.

3. When replying to a posting (message), kindly delete all
unnecessary text including the trailing text. Only leave the text
from the prior message to which you are replying ... <snip> the
rest. If one desires to read the entire thread, the command [Up
Thread] at the top of the message can be used to read the entire
discussion. Remember also that a lot of members have slow
connections and some even pay connect time or characters rx/tx. This
also helps the clarity of your message.

4. When replying to a post, please decide if your comment should be
to the entire group of about 10,000 or directly to the author of the
post. When you click on "Reply," it goes to everyone. To reply
direct (simplex), you should click on the email address following the
user ID line at the top of the post. Notice that only a part is
shown for privacy. Also, please think about if what you are about to
post in reply to the group really should be to the group ... replies
like "I sure do agree with that" doesn't add much to the group. Send
thoughts like those direct to the poster please.

5. It is fine for members to post something for sale or wanted to
buy ... once per item(s). All questions and offers to buy/sell
should be made directly to the poster, not to the Group. The member
posting the FS or WTB may post that the item(s) was/were
sold/purchased.

6. Posting of commercial items for sale by manufacturers or dealers
is also fine, but should be done on an infrequent basis. The FT817
members benefit by learning of hardware, software, sales, etc. before
it appears in magazines, etc.

7. New members are all moderated until their first posting. If it
follows the guidelines, it is approved and the member is change to
unmoderated status. This list is a partially moderated list, i.e.,
only first message is moderated while later messages are monitored
after posting. If an unmoderated posting is found by the moderators
to have a problem, then the poster is contacted directly to resolve.
Actions are taken against those that chronically violate the rules.
The reason for this form of moderation is to block spammers from the
list and it has been working.

8. Do not add disclaimers to your posts that (1) restrict the ability
of other members to use the information you post, (2) claim a copyright
to your post, or (3) to claim any type of "rights" as a consequence of
another member replying to your post either directly to you or to the group.

Thanks to all es 73,

Re: FT-818ND new UHF filter performance?

Mike Olbrisch
 

This is interesting. I’ve often said YAESU should not make the new FT-817 (now FT-818 I guess) into another scanner. We don’t need a worked all pagers award. What we need is tight filtering for weak signal work without intermod creeping in. The FT-817ND could be better, but wasn’t too bad as it was.



So it sounds like they left the 2m section alone (not great, but not as bad as it could be), but made the 70cm band worse. Too bad. It seems like every other radio out there has a V/UHF front end as broad as a barn door. The 817ND was one of the few not plagued too badly with RX issues.



I look forward to hearing more about the 818. And I may want to pick up a third clean FT-817ND if the 818 does have a weaker front end on 70cm. I don’t need a stinkin scanner, but I do value the 817 for what it is, a very nice weak signal radio for hilltops and rover operations.

I had my FT-818 running for a couple of hours on CW/SSB in the 432 MHz Spring Sprint recently. I was portable in a hilltop park with an 11 element horizontally polarized Yagi. All went fine, but I did notice a number of narrow-band digital-sounding non-amateur signals which I don't recall hearing before at that location with my old Microwave modules transverter and a rather broad bandpass filter. There was no RF source outside my car for a couple of hundred metres, but several radio towers line-of-site within 2 km, and several small cities, also line-of-sight, at greater distances. The car is a new one since I last operated there on 432, as well...so that's another uncontrolled RFI factor.



I don't know if those signals were in-band spurious emissions or if, as you suggest, they could have been on image (or other out-of-band) frequencies. It would be an interesting experiment to try a bandpass filter at that site and see if those signals disappear. Unfortunately I don't own a good one for 432 MHz.



Thanks for pointing out the image rejection issue...perhaps I should invest in a better bandpass filter if I plan to use the '818 for more serious endeavours on 70 cm.

FT-818ND new UHF filter performance?

Simon Gale
 

Hi, I'm considering purchase of a FT-818ND but have some concerns about the UHF performance of the 818 compared to the 817 and would be grateful if anyone has experience of the 818 70cms performance, particularly image rejection.

The original 817 had a 3 section helical RF filter for 70cms but it looks like this has been replaced with a two section(?) lumped element filter as seen from the photos in http://radioaficion.com/cms/ft-818-review-and-disassemble/.?? If anyone has seen the schematic I would be interested to know any more details of the new filter arrangement. ?

The 817 looked to meet or well exceed the 70cms image rejection spec of 60dB, however the recent review in the Jan QST reported only 38dB for this on the 818 sample they measured (https://static.dxengineering.com/global/images/technicalarticles/ysu-ft-818_gi.pdf).? Perhaps the filter was misaligned in this test sample?

Any feedback much appreciated as 70cms is important to me and only 38dB of image rejection is not wonderful.

Many thanks

Re: FT-818 Odd SWR Readings on 70 cm

 

Thanks, Eric.? Assuming the menu is the same in the FT-818 as in the FT-817, it appears that the parameters available there are for the sensitivity of the power foldback (high SWR protection) to the SWR reading, rather than the calibration of the SWR meter itself, but the details I found are a bit sparse.

KA7OEI did point out that on his FT-817 (original) a perfect load gave 2 bars of SWR reading at 5 W on a perfect load.? He found the adjustment instructions for this in the service manual, but it didn't actually work without circuit modifications.? It may be that my FT-818 is just a bit worse!

FT-818 new UHF filter?

 

Hi,? I'm considering purchase of an FT-818 but have? some potential concerns over the capability of the new 70cms RF filter design in the 818 vs the 817.?

The 817 had a 3 section helical filter that resulted in very good image rejection performance, mostly exceeding the 60dB spec by a significant amount.? Looking at the 817 vs 818 teardown at it looks like the 818 has replaced the helical filter with something that looks like a 2 section lumped filter (has anyone seen the schematic to confirm please?).


I noticed the 818 review in the Jan QST ( ) reported that the ARRL measured a 70cms image rejection of only 38dB, well below the 60dB spec.


Perhaps the ARRL sample unit was not correctly aligned, I would be most grateful if anyone has noticed this performance aspect please as 70cms performance is quite important to me.


Many thanks


Simon
