Highlight of this report: "HI" "Hiker?" CW Morse beacon at 7998 kHz
Report

7998.08 kHz CW, Morse beacon, "HI", "Hiker?", weak readable, -122 dBm.

Haven't heard HI in several days. Hearing a short dasher, about every 4-5 sec, ~7998 kc at 2315 UTC.

Here's the big question: "Is the HI beacon the new incarnation of Hiker (https://www.hfunderground.com/board/index.php/topic,27043.msg146374.html#msg146374)?"
And yes, that 7998 kHz dasher or ditter is also logged here, weak readable.
But the timing seems somewhat irregular.
Makes one wonder if it is a beacon or not.
It could be one of the other mystery signals, because is very very much like many of the similar slow communication signals logged just like it in western USA, but on various other frequencies.

Ask and ye shall receive. HI with a nice 569 signal at 0035 UTC.

I have not had
much any luck with these beacons lately. The problem is I don't know when the short window of propagation to my QTH currently is. I'll need to leave the SDR running today and see if I can figure out when they turn up here (if at all).

Am hearing HI this morning at 1745 utc. Good signal.

Is the HI beacon the new incarnation of Hiker?

Hearing HI here in Pinal County AZ fairly strong with some fading. 1/26/2019 23:15z 7998.120 KHz

HI was not around earlier today but is very strong now with minimal fading. 22:35 UTC 03MAR2019. 7998.07 KHz.
-
HI fading up to 559 around 0015 UTC Mar 04. Lots of QRM from OTHR. Faded out completely around 0030.

Good catch!

Great catch!
"HI" beacon sometimes seems to be elusive.

Extremely! I have yet to catch it here, I need to figure out when the (probably brief) window of propagation is, if there is one. I've tried mornings without success, I need to try evenings next.

Hearing HI off and on this morning here in UT. 1630 utc

HI has appeared for the first time today here in central AZ. 19:56z 09MAR2019.

Logged it here also.
Then it distinctively went off the air while monitoring it.
It seems to transmit on an irregular basis.
When checked 2 hours ago, negative copy.

I agree, I do not think it is on the air continually. I as well have seen it just appear all of a sudden as well as disappear. Does not always seem to coincide with changes in propagation.
-
Just bounced back over to 7998 and HI has now returned.
09MAR2019 23:36z 7998.07 KHz, fairly strong then fades out for a transmission or two.

Has anyone copied HI recently?

I've tried off and on a few times and not heard any of the 7-8 MHz beacons. Nothing but A and Windy here.

I've yet to catch any of the 6 MHz beacons here in SoCal and am wondering if they are even maintained any more. It takes time and effort to drive/hike to remote locations, diagnose problems and effect repairs in austere conditions.

I can imagine it does. I did hear some of the circa 8 MHz beacons a few years ago, but nothing recently. I don't think the circa 6600/6700 kHz ones ever made it here. I expect that solar powered beacons are mostly a southwest desert phenomena where you have lots of sunshine, they probably would not do well in our cloudy/rainy/snowy weather here in the northeast.

From what I have gathered some of the beacons in California started out operation equipped with batteries but once the batteries went bad the system was left in place to operate as daytime only
