该台被短波追踪者命名为 V32，为约 25 年来首个被辨识、以波斯语播出的此类电台；先例之一是在 2001 年美军入侵阿富汗期间短暂出现的波斯语数字电台，因其数字模式而被部分观察者怀疑可能由俄罗斯操作。V32 目前依伊朗时间每日两次播出：上午 5:30 与晚上 9:30，各持续约 1.5 小时；其讯号曾在数日内被电子「哔啾」声短暂淹没，被推测为伊朗干扰，但随后迅速改频续播。
由于短波可被任何接收者收听，外界无法确定听众与发信方；然而这正是 number station 的优势：除非操作失误或特工被当场抓获，反情报单位通常只能尝试干扰频率。监听组织 Priyom 以到达时间差粗略三角定位，指向西欧；评论者亦提出替代解释，包括 Robert Gorelick 所称伊朗异议者可能借此通联，或用以加剧德黑兰反情报疑惧。此现象虽自冷战后式微仍未消失，波兰、俄罗斯、台湾与北韩等仍被认为持续运作规律数字电台。
A Farsi-speaking shortwave “number station” began broadcasting from somewhere in western Europe in the hours after the first US and Israeli strikes on Iran on February 28, featuring repeated calls of “Tavajjoh” and spoken number strings (for example, “6, 4, 0, 9, 3, 9”). Former CIA officials such as John Sipher assess it is likely an emergency fallback channel to keep one-way contact with agents inside Iran if internet links or phone services are cut.
The station, dubbed V32 by shortwave trackers, is the first identified number station broadcasting in Farsi in about 25 years; one earlier Farsi numbers service briefly appeared during the 2001 US invasion of Afghanistan and was suspected by some watchers—based on number patterns—of possible Russian operation. V32 now runs twice daily at 5:30am and 9:30pm Iranian time, for roughly 1.5 hours each session; after apparent jamming sounds briefly drowned it out within days, it shifted frequency and resumed.
Because any shortwave listener can receive the signal, the operator and audience cannot be confirmed, but that openness is a core advantage: absent mistakes or an arrest caught in transcription, counter-intelligence can do little beyond jamming. Priyom members used time-of-arrival triangulation to place the source roughly in western Europe; alternative hypotheses include Robert Gorelick’s suggestion of Iranian dissidents using it, or a psychological ploy to increase Tehran’s counter-intelligence pressure. Although the phenomenon has declined since the cold war, it persists, with Poland, Russia, Taiwan, and North Korea among countries thought to run scheduled number stations.
