HM01 log, April 2019

To see what this is all about, go here: https://www.hfunderground.com/board/index.php/topic,32334.0.html

All transmissions received in Denver, CO, USA using an SDRplay RSP2pro and a W6LVP active loop antenna on the dates, times and frequencies noted.

Date (DDMMYYYY):   Numbers:    File name or repeat:  Frequency (kHz) and time(UTC):
01/04/2019              18253         50631825.f1c *          11435   1600
                               65311         74016531.txt *
                               55104         04445510.txt *
                               83886         22748388.txt *
                               28556         76652855.txt *
                               23037         47352303.txt *
* This particular set of numbers and files was first sent on 22 FEBRUARY 2019. HM01 has been repeating them every day since then. In recent months they will broadcast the same number sets and files for weeks or even months on end, then on some random date they'll transmit an entirely new set. Sometimes that new set will progress normally for a few days and then begin to repeat daily, other times the repetitions begin the very next day. 
A link to download these files can be found in the February log posting. They will not be included with any new files that will be transmitted in March.

I'm going to do something a bit different. Since HM01 has spent most days resending the same number groups and files for at least a year now, I'm only going to note the date, time, and frequency that I observed these repeats. If they happen to send new numbers and files, or even if they simply start advancing the final digit of the number groups as they used to, I will post the full information on that date. Until then, I'm keeping it simple.
